Safety Instructions
•WARNING! Read and understand all instructions. Failure to follow all instructions
listed may result in electric shock, re and/or serious injury.
Installation/Assembly
Carefully unpack the sharpener. Check to see that no damage has occurred in shipment. Check
all packing materials to be sure that all parts are present. Refer to the packing list.
•DANGER! Electrical shock can kill! Read, understand and follow ALL safety instructions.
•WARNING! Connect to properly wired (110V or 230V, as applicable) outlet, or
electrical shock may occur.
•CAUTION! Do not operate the sharpener without the vacuum system running.
Grinding dust inhaled/ingested can be harmful to your health. Grinding particles will cause
damage to the internal machine components.
Work Area Safety:
• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating the sharpener. Distractions can
cause you to lose control. Do not let persons not involved in the work touch the sharpener or
power cord.
• Make workshop kid proof with padlocks, master switches or by removing starter keys.
Electrical Safety:
•WARNING! Do not expose power tools to rain or wet conditions.
Water entering the sharpener will increase the risk of electric shock.
• Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodied plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
sharpener. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
• Disconnect tools. Always disconnect your power tool when cleaning, inspecting, and
changing attachments. When not in use, disconnect from the power supply. Never touch
internal parts of the sharpener when it is turned on or plugged in. The rotating diamond
wheel can cause injury.
• Grounding instructions. In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to reduce risk of electric shock.
This sharpener is equipped with an electric cord having an equipment-grounding conductor
and grounding plug. Do not modify the plug provided. The plug must be plugged into a
matching outlet that is properly installed and grounded (110V or 230V) in accordance with
all codes and ordinances. Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with a qualied electrician or serviceman if the
grounding instructions are not completely understood, or if in doubt as to whether the tool is
properly grounded. Do not use an extension cord.

• Replace damaged or worn cord immediately. Call Darex® Technical Support for assistance.
• Grounded, cord-connected tools intended for use on a supply circuit having a nominal
rating less than 150 volts: This sharpener is intended for use on a circuit that has an outlet
that looks like the one illustrated in Figure B, below. The tool has a grounding plug that
looks like the plug illustrated in Figure A. A temporary adapter which looks like the adapter
illustrated in Figures C and D, may be used (except in Canada) to connect this plug to a
2-pole receptacle as shown in Figure B if a properly grounded outlet is not available. The
temporary adapter should be used only until a qualied electrician can install a properly
grounded outlet. The green colored rigid ear lug, Figure D, extending from the adapter must
be connected to a permanent ground such as a properly grounded outlet.
Personal Safety:
•WARNING! Sharpening operations can create hot sparks and metal debris, loud
noises and dust!
• Stay alert - watch what you are doing and use common sense when operating a power tool.
• Do not use a power tool while you are tired or under the inuence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
• Use Personal Protective Equipment (PPE). Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions will reduce personal
injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to
a power source.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the sharpener may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better
control when using the sharpener. Nonslip footwear is recommended.
• Dress properly. Wear closed, non-ammable protective clothing. Do not wear loose
clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in moving parts.
• Secure work. Use clamps or a vise to hold work when practical. It’s safer than using your
hand and it frees both hands to operate tool.
• Never leave tool running unattended. Turn power off.
• Do not touch internal parts of the sharpener when it is on. The rotating wheel can cause injury.
Sharpening Tool Use And Care:
•WARNING! Use recommended accessories. Use the power tool, accessories, abrasives,

•CAUTION! Keep power tools and work space clean for best performance and safety.
• Maintain sharpener with care. Many accidents are caused by poorly maintained power
tools. Follow instructions for lubricating and changing accessories. Check for misalignment
or binding of moving parts, breakage of parts and any other condition that may affect the
sharpener’s operation. If damaged, have the sharpener repaired before use. Keep unit dry,
clean and free from oil and grease.
• Do not let sharpening debris accumulate on, in, or around the tool. Accumulated ne
metal sharpening debris can be very hot and may present a re danger if the machine or your
workspace is not properly cleaned and maintained. Accumulated sharpening debris can also
degrade the life of the tool and cause premature wear on some components. If sharpening
debris has accumulated, do not immediately throw it into a trash receptacle without ensuring
the debris is completely cool and free of heat. Improperly disposing of the accumulated
sharpening debris may present a re risk. Do not collect the sharpening debris during
sharpening. This increases the risk of heat build-up in the debris and the potential for re.
•CAUTION! When maintenance is performed on the sharpener follow the instructions.
• Press the emergency stop button, unplug unit from power source and use a “Lock Out/
Tag Out” procedure.
• Do not force the sharpener or an attachment. It will do the job better and safer at the rate
for which it was designed.
• Do not use the sharpener if the switch does not turn it on or off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments, changing
attachments, or storing the sharpener. Such preventative safety measures reduce the risk
of starting the sharpener accidentally.
• Store idle power tools out of reach of children and do not allow persons unfamiliar with
the sharpener or these operating instructions to operate the power tool. Power tools are
dangerous in the hands of untrained users.
• Keep guards in place and in working order. A guard or other part that is damaged should
be properly repaired or replaced by an authorized SERVICE CENTER unless otherwise
indicated in the operating instructions.
• Never stand on the sharpener. Serious injury could occur if the tool is tipped or if the
sharpening edge is unintentionally contacted.
• Check damaged parts. Before further use of the tool, a guard or other part that is damaged
should be carefully inspected to determine that it will operate properly and perform its
intended function. Check for alignment of moving parts, binding of moving parts, breakage
of parts, mounting and any other conditions that may affect its operation. A guard, defective
switch, or other part that is damaged should be properly repaired or replaced by an
authorized SERVICE CENTER unless otherwise indicated in these operating instructions.
• Do not use if the grinding wheel is damaged. Use only grinding wheels recommended by
Darex®. Follow instructions provided in this operating manual for changing the wheel. The
wheel must be removed in order to clean it. Do not over-tighten wheel nut. Use only anges
(or washers) furnished with the grinding wheel.

XPS-16+ Specifications
XPS-16+ Automatic Measurement Features
Your XPS-16+ has many features so carefully designed and engineered that you may not even
be aware of their uniqueness. Once the cycle start button has been pressed, your Darex XPS-
16+ begins taking measurements of the drill on the way to the grinding wheel. It locates the end
of the drill, calculates diameter, locates and positions the cutting edge, determines web thick-
ness, identies initial contact point of drill to the wheel and then sharpens. After sharpening
and before splitting the drill, the sharpener again measures and re-locates the end of the drill,
ensuring an accurate split.

12
Diameter Icon
The [AUTO] mode is the factory default setting. In this mode, ‘auto’ will appear
under the Diameter Detect graphic. In the event the drill diameter is different than
the work holding diameter, it will be necessary to enter the actual drill diameter.
To do so:
1. Press the Drill Diameter icon.
2. A keypad will appear.
3. Type in the drill diameter including
the decimal point.
4. Press the [CHECK] icon to enter the
value and return to the main menu
5. Notice the [AUTO] has now been
replaced with the value just entered
Note: If the XPS-16+is in the [AUTO] mode and the drill diameter is measured
at less than .115”, the XPS-16+ will automatically return to the home position
and prompt the operator for additional information (Single Point Alignment or
Manual Align). The programming of these features will be covered in the Web
Detection section of the User Guide.
Tip: The machine can be operated in either inches or millimeters. To change
between them, press the INCH/MM icon. The value displayed on top in the bolder
font is the current selection for all the applicable icons.

Tip: Use “MIN” when cleaning up a dull drill bit.
Tip: Use “MID” or “MAX” when changing point angle or repairing damaged drill bit.
Range
.000 - .010”
Range
.005 - .015”
Range
.015 - .020”
(conic only)
Note: If the point angle entered is beyond the machines limits, the XPS-16+ will default to the
nearest value the machine is capable of grinding.
If the desired grind angle is less than 115°, the XPS-16+ will automatically prompt the op-
erator for additional information. The programming of the [Web Thickness] and [Advance]
features will be covered in the [Web Detection] section of the User Guide.

13
Manual Align Icon
This mode bypasses the Automatic Align mode and
proceeds directly to sharpening the drill. In this
mode, the operator is responsible for placing the drill
in the chuck with 1 cutting edge vertical (12 0’clock)
• Press the [ALIGNMENT] icon. A key will appear. Press the [AUTO]
icon to toggle to the [MANUAL] mode on the lower left corner of the
touch screen. Press the [CHECK] to return to the main operating
screen. Notice the ‘auto’ has been replaced with ‘align’ in the icon.
Tip: Because the drill alignment operation is not executed, the Manual Align mode
it is faster than Auto or Single Point Alignment modes. However, because the op-
erator is responsible for cutting edge alignment, there may be variation in results.
Tip: This feature is benecial for very small drills or in the event there is an issue
with the ber optic system.
Vertical
Cutting Edge
Automatic Alignment Icon
The [AUTO] mode is the factory default setting. This enables the XPS-16+ to perform
several calculations necessary to correctly align the drill prior to sharpening with the
pre-programmed drill geometry. There are some instances previously mentioned in
the User Guide where the machine cannot make these calculations. If these conditions
occur, the XPS-16+ will interrupt the grind operation, return to the home position and
prompt the operator for the necessary information. Press the [OK] icon on the touch
screen to enter this feature or press the [Alignment] icon
Web Thickness (manual input)
In order to activate the Radius Split or Single Point Alignment feature, it is necessary to measure
and enter the web thickness of the drill. To do so:
• Press the [ALIGNMENT] icon - a keypad will
appear.
• Measure the Web thickness of the drill with
calipers and enter this value on the touch screen
including the decimal point. Press the [CHECK]
icon to return to the main operating screen.
Tip: Notice the [AUTO] in the Web Detection icon has been replaced with the web thickness
value just entered
Web Thickness
There are 3 different modes of drill bit cutting edge alignment available with the XPS-
16+. In order to sharpen the different drill types and sizes, one mode may be better
suited than another mode. All 3 modes are accessed via the Web Thickness/Alignment
Icon on the Main Sharpening screen.
Tip: Remember, sharpening begins with the drill alignment and the nal
sharpening result depends on how accurate the cutting edge is oriented.

14
Hone Icon
Normally only used for edge preparation on carbide drills.
There are 3 different hone modes on the XPS-16+. Press the [HONE ICON] to toggle through
the hone options including turning the hone option off. The duration the drill edge is honed and
the position of the drill as it enters the hone is controlled in the [TOOLS] icon. This will be
covered later in the user guide.
Advance Icon
When the [Advance] feature is used, the XPS-16+ is nding the cutting edge using a single
point of alignment. The [Advance] feature is located in the upper right hand corner of the
Alignment icon and is activated by entering any value other than zero.
There are several drill types that will require an [Advance] value to be entered by the operator.
They are:
• Drills with ‘hooked’ cutting edges
• Drills smaller than .115” (3mm)
• Drills with a point angle of less than 115°
• Facet sharpened drills where the intersect line separating the primary and secondary facets are not
parallel to the cutting edge.
Tip: See “Creating a Conic-Style Drill, Set-by-Step” and “Creating a Facet-Style Drill, Set-by- Step”
for more detail on how to utilize the [ADV] function.
Tip: To align the cutting edges vertical for a standard web drill, the [ADV] is usually +15 to +22
degrees. For a thick web drill, the [ADV] is usually +2 to +8 degrees.
To conrm position, press cycle start [Green Button].
After the diameter detect routine, make sure the cutting edge of the drill is positioned
at 12:00 o’clock (vertical) just prior to the drill touching the grind wheel to conrm
position. Upon approaching the grinding wheel, a facet-style drill will rotate slightly
counter-clockwise — this is normal. If the cutting edge orientation is not correct, press
the cycle interrupt (yellow) button to halt the process. Either press the cycle interrupt button again
or press the [HOME] icon on the touch screen to return the XPS-16+ to the home position.
Using the [C] axis decal on the back of the chuck as a reference, return to the Advance [ADV]
feature in the [ALIGNMENT] icon and make a calculated estimate as to the direction and
amount of correction.
Tip: If this drill is to be ground on a continued basis, it is recommended that this information
be saved as a Drill le. This feature will be covered in the [FILE MANAGEMENT] portion of
the User Guide.
[NO HONE] is the
factory default mode..
[HONE SINGLE] – Applicable for
honing the drill cutting edges only.
[HONE DOUBLE] –
Applicable for honing both the
drill primary cutting and the
secondary cutting edge that are
created when the drill is split.
[HONE ROTATE] – The drill is
continuously rotated during the
hone process. Enter hone times in
even numbers to avoid asymmetric
honing.

15
Split Point Icon
There are 3 split options with the XPS-16+. They are:
Tip: If the user wishes to only split the drill and skip the sharpening funtion, turn off the hone
and point style icons by pressing both until an “X” comes across the image.
The XPS-16+ can be used as a HONE ONLY machine. This is accomplished by deactivating
the [SHARPEN ICON] and the [SPLIT ICON]. This feature is benecial for new carbide
drills that have not received a cutting edge treatment. Hone times vary depending on the drill
size and the type of hone being used. When using the provided Silicone Carbide Hone, use 6,
12 & 18 seconds for small, medium and large drill bits respectively. If using a Diamond Hone
(option), reduce those times by 50% for the different drill sizes.
Tip: Honing the cutting edge of a carbide drill prolongs drill life and results in better hole-size
consistency between sharpening.
Tip: A longer hone time produces a larger cutting edge radius. Trial and error is needed to
determine the best cutting edge radius for each individual drill application. Factory default is 1
second for each mode.
Drill Style Icon
The XPS-16+ can sharpen 2 different drill point styles: Conic and
Facet. Step by step instructions to sharpen each point style are on
pages 20 and 21.
Relief Adjustment
Press the [RELIEF ADJUSTMENT] icon to
adjust relief from 5°-18° (accurate to +/- 2°). If
the relief value specied is beyond the allow-
able range, the XPS-16+ with automatically
default to its allowable range prior to sharpen-
ing. Press the [CHECK] icon to accept the
value or the [X] icon to exit to the Main user
interface screen.
[NO SPLIT] – disables the split feature if that is desired
[X SPLIT] – This is the factory default mode with several settings predetermined by
the manufacturer; including X and Z axis offset settings, the Fan Angle and the Split
Angle. All of these settings can be altered by the user. These settings will be covered
under the [POINT SPLIT OFFSET] screen in the [TOOLS] menu later in the User
Guide.
[RADIUS SPLIT] – This feature is only available by pressing the [ALIGNMENT]
icon. Measure the web thickness with calipers as shown and using the keypad, enter this
value including the decimal point. Press the [CHECK] icon to return to the Main Menu
screen. Return to the [POINT SPLIT] icon. You will notice that the [R SPLIT] feature
is now an option when you continue to press the [POINT SPLIT] icon. All geometric
parameters for the Radius Split Point are controlled using the [POINT SPLIT OFF-
SET] screen in the [TOOLS] menu to be covered later in the User Guide.

Darex Representative for customer service.
Drill Material Icon
Pressing this icon will prompt the user to execute a grind wheel change, CBN for HSS/
Cobalt and Diamond for carbide drills. Changing to the correct icon internally adjusts
some of the grind stock removal and grind speed rates.
Tip: Even though the XPS-16+ prompts the operator for a grind
wheel change, the machine does not know if that grind wheel
change has been executed. Using the incorrect grind wheel will
have a negative effect on grind wheel life.
Tip: After a grind wheel change, it may be necessary to make an offset adjustment to
the grind wheel face and/or the grind wheel edge. Those adjustments will be covered in
the Wheel Position Adjustment portion of the User Guide.

Point Split Offset Icon
Select the point split type you wish to grind using the Point Split icon already covered in the user
guide. Any split geometry you wish to alter can be adjusted using this menu. The user adjustments
are:
Pressing the Z axis offsets (plus
and minus) which will control
split depth.
X axis offsets (plus and minus)
which will control the center of
the split.
Tip: Each axis is dened by a
decal applied to the Base Casting
showing direction of movement.
Reference these decals when
making offset adjustments to either the Xor Zaxis. Movement increments are in 1/1000th’s of an
inch or .025MM if the utilized in the metric mode.
Radius Split
In order to create a radius split, the user must rst measure the web thickness and
manually enter the gure into web thickness screen. Press the split icon until the
R-Split option appears. When the R-Split is selected, the point split offset icon will
display an R-Split option. When the R-Split is selected, the Point Split Offset page
will have all the X Split offset adjustments plus some additional ones. In the upper
right hand corner of the Point Split Offset menu will have [R-Split] icon. Press
this icon to allow you to make adjustments to the amount of radius [OFFSET] and
