Weight........................................................4.84 lbs
OVERVIEW:
Special Features
The KDM110 has a number of special features. The unit is
designed to power both the pneumatic drill/polisher and the
vacuum base using a single airline. The Venturi vacuum base
was designed to deliver powerful suction to hold the unit
securely in place even on rough and textured materials such
as the underside of granite and ceramic surfaces in wet or
dry conditions. The vacuum base allows the unit to be
operated in a vertical or horizontal positions, provided
sufficient air pressure and volume is available. The vacuum
base also has a convenient quick release system to allow the
user to quickly reposition the unit without shutting off the
air line. Simply cover the small circular opening located on
the front of the Venturi block (19) with your finger and the
suction will be temporarily disengaged. The front of the unit
has a slot to accept a wrench allowing the user to change
drill bits without removing the polisher from the base. Simply
slide the included wrench into the slide and engage the
spindle on the Alpha Air-680C. This will prevent the spindle
from rotating. You can then use the appropriate wrench to
attach/remove your drill bit. Lastly the KDM110 has an
integrated depth stop that allows a predetermined depth
to be set for repeatable, accurate drilling.

DRILLING MACHINE MANUAL
Air Pressure & Volume
The recommended air pressure for this tool is 85 PSI. The most
important factor in running this tool is the volume of air being
supplied to the tool. The volume is the air consumption needed
to run this tool at a constant speed under light downward hand
pressure. The volume is measured in CFM (cubic foot per
minute (ft3/min). You need a minimum of 16 CFM per tool to
power both the tool and the vacuum base effectively.
When choosing a compressor to run an KDM110 we recommend
a rotary screw type with a minimum of a 5 hp motor/15-20 CFM
and a 60-gallon tank, per tool. (I.E. if you want to run four tools,
you will need a compressor with a 20 hp motor capability of
80+ CFM and an 80 to 100-gallon storage tank.) It is also very
important to keep your air cool, dry, and clean, so look for a
compressor with a refrigerated dryer and high-efficiency filter
built in or purchase a separate air dryer and filter unit rated for
your compressors CFM. Also ensure that the hose feeding the
KDM110 is of sufficient diameter to provide the required volume.
½” Hose is recommended.
Tool Set-up Information
Unpack the tool carefully and study the manual. Set the tool on a
level surface and inspect for damage.
Before use, ensure that the Alpha AIR-680C is securely clamped
into the clamping block (15), using a ⁵/₃₂” Allen wrench. If the
drill is not clamped securely in the clamping block the drill
may come loose during use. Excessive force and/or insufficient
air pressure/volume may also force the polisher from the
clamping block.

Drill Bits
This machine is compatible with a variety of ⅝” x 11 threaded
drill bits. Specially designed drill compatible with the Keep-nut
anchoring system are available for this unit. The standard bit
included in the box is recommended for marble, granite, quartzite
and other natural stone surfaces. We recommend specialized bits
for drilling ceramic/porcelain and specialized drill bits for glass.
A variety of core bits are available for this machine as well for
drilling faucet holes and other applications where core-bits are
used. The max drilling depth on this unit is approximately 1¼” (3CM).
See below for a chart showing average drilling time to drill a ¼”
depth hole using the included drill bit.
For optimum drilling of porcelain, sintered and ceramic materials,
a higher RPM tool is recommended. The KDM110 can be used to
drill accurate holes in these surfaces when using a bit designed
for these materials, but drilling times will be considerably longer
compared to granite and marble.

If the unit looses suction and the vacuum is
unable to securely adhere to the surface the
most likely cause is a blockage in the venturi.
Debris can become lodged in the venturi
which prevents the unit from creating enough
suction. To correct this, the venturi needs to be
disassembled and the blockage removed.
Once the obstruction is removed the unit
should return to full functionality.
Follow the steps below:
1. Using a hex key loosen the screws (4) that
secure the venturi block (19), and remove
the venturi block from the base.
2. Using the appropriately sized wrench
remove the ¼” NPT fitting (12) on the
venturi block.
3. Remove the value (13) inside the
Venturi block.
4. Visually inspect for any debris
trapped in the Venturi block; Use a
blow gun to clear out any debris
lodged in the cavity.
5. Reassemble parts as shown in the
parts diagram on page 5 & 6; Check
for proper suction.

KEEP-NUT™
DRILLING MACHINE MANUAL
If the vacuum is unable to securely adhere to
the surface while drilling it is likely that the
Venturi has insufficient air pressure/volume.
With proper air flow the vacuum base should
have plenty of suction to stay in position during
use even while applying moderate force to the
handle while drilling. Check your air supply for
pressure and volume and make sure your airlines
are of sufficient diameter to supply the machine.
If proper air pressure is being supplied make
sure that the bit is properly dressed and cutting
freely. Do not apply excess pressure to the
handle during use. Excess pressure can damage
the Alpha Air-680C polisher and cause the
vacuum base to lose suction.
If the KDM110 is drilling holes that are too large
for the keep-nut anchors, ensure the correct
bit is being used. If the correct bit is in use, you
may need to add a ⅝” washer between the
drill bit and the polisher to insure that the bit is
seated exactly 90° from the polisher. If the bit
has insufficient thread depth this can cause a
misalignment which will affect the final diameter
of the hole produced.

The recommended air pressure for this tool is 85 PSI. The most
important factor in running this tool is the volume of air being sup-
plied to the tool. The volume is the air consumption needed to run
this tool at a constant speed under light downward hand pressure.
ThevolumeismeasuredinCFM(cubicfootperminute(ft3/min).You
need a minimum of 15 CFM per tool.
When choosing a compressor to run an AIR-680C polisher, we rec-
ommend a rotary screw type with a minimum of a 5hp motor/15-20
CFManda60gallontank,pertool.(I.E. if you want to run four tools,
you will need a compressor with a 20hp motor capability of 80+ CFM
and an 80 to 100 gallon storage tank.)
It is also very important to keep your air cool, dry, and clean, so look for a
compressorwitharefrigerateddryerandhigh-efciencylterbuiltinor
purchaseaseparateairdryerandlterunitratedforyourcompressors

Attheendofeachworkday,place2-3dropsofrustinhibitoroil(in-
cludedwitheachpolisher)directlyintotheOILPORTofthepneumatic
tool. After applying the rust inhibitor oil, turn the air valve slightly so
that the oil atomizes into a mist and coats the internal components
ofthepolisher.Iftheprocessisexecutedcorrectly,youshouldsee
a mist coming out of the end of the polisher. The Exhaust Hose
