General Information
CRL has designed this machine specifically for use in glass drilling by industry professionals. You must use the
machine only for the designated purposes. We are not responsible for any accident which may be caused by
misuse. As you begin familiarizing yourself with the machine, pay attention to the following details:
• Do not work on porous surfaces. This unit is designed for glossy surfaces, such as glass.
• Never change the speed of the machine when the diamond drill is in contact with the glass.
• Make sure you are feeding a sufficient amount of water while drilling.
• Watch the condition of the glass when drilling to determine correct drill speed.
• Keep speed and water feed constant until the drill bit is completely removed.
• Do not disassemble the machine. This will void your warranty.
ELECTRICAL REQUIREMENTS
Your AMZ1 Machine has been shipped ready for 110 VAC power. The machine features a heavy-duty supply
cord with grounded 3-prong plug. This machine should always be used on a grounded outlet with built-in
ground fault -circuit protection. If you do not have a G.F.C.I. protected outlet, contact us to purchase our
portable in-line G.F.C.I. device, CRL Cat. No. GF1. This machine should not be used with extension cords.
Plug directly into grounded outlet.
Your AMZ1 Machine features an electronic speed control that will accept 110 or 220 volt input in either 50 or
60 cycle power. To use this machine with a 220 volt circuit, contact a qualified electrician to provide you with a
properly fused and grounded circuit, and to supply connections.
SAFETY
This AMZ1 Machine is suited for use by glass industry professionals. The operator must understand the nature
of glass and observe safe, accepted handling procedures for glass before use. Incorrect and careless use of this
machine will decrease the durability of the product and can cause serious injury. Please read all of the
instructions -thoroughly before use.
When working with the AMZ1 Machine, please note the following precautions:
• Wear appropriate eye, hand and body protection.
• Provide properly grounded G.F.C.I. protected electrical connection.
• Adjust RPM to suit diameter of diamond drill being used.
• Never touch diamond drills while in operation.
• Support glass properly before setting machine on glass.
• Glass must lay horizontal and be stress free.
• Never drill glass in the vertical position.
• Use only designated tools to insert a diamond drill in the chuck.
•Unplug machine when changing diamond drills.
• Block small pieces of glass securely.
• Do not use on tempered or wired glass.
• Keep the control box and motor dry at all times.

WORK AREA
This machine is designed to be portable for use at the job site, as well as for in-shop use.
Always provide an uncluttered work area and concentrate on the job at hand.
Before using your machine, please organize your work area to ensure the following:
• Glass must lay flat without stress.
• Glass must be adequately supported to accept weight of machine.
• The diamond drill must be able to protrude through the bottom of the glass when drilled.
• There must be a collection system for the used coolant.
For in-shop use, drilling can be done on a flat cutting table using a thin piece of Plexiglas between the glass to
be drilled and the cutting table. Direct used coolant to a collection area.
For temporary portable work, you can create a work area by laying a plastic sheet over a flat surface, such as a
portable cutting table. Use quality straight wood strips (1” x 2” or larger) and place flat on top of the plastic
sheet to elevate the glass work piece. Position the flat strips to adequately support the work piece, maintaining a
flat plane. Allow the coolant to flow off the plastic sheet into a five gallon bucket for settling and reuse. After
use, clean any glass residue or coolant off the drills, drilling machine and the base. Dry completely.
PREPARING TO WORK
Your AMZ1 Diamond Drilling Machine is designed for the water or water/diamond coolant mixture to be fed
through the center of the diamond drill via the water coolant chuck. The coolant chuck uses this water flow to
provide cooling to the chuck body and seals. Whether you are using the optional coolant supply container, or
your building water supply, you should always keep coolant flowing when using the machine.
The operating speed (RPM) is adjustable from 0 to 2900 RPM. This allows user to set the optimum speed for
different diameters of diamond drills. Smaller drills run at higher speeds, and larger drills run at lower speeds.
See instructions packaged with each diamond drill for optimum speed selection.
The AMZ1 Machine is held to the glass while drilling with two rubber locking cups. You may adjust the
holding power of these cups by adjusting the knurled washer on the top side of the cup. To release cups, lift
lever and pull up on side of cup with fingers to release pressure. Use care to prevent cutting or scratching of the
rubber cup -surface during transport and storage.
USING THE AMZ1 MACHINE
1) Mark the glass where you want to drill.
2) Using the wrenches provided, install a drill in the machine.
3) Plug machine into a properly grounded G.F.C.I. protected outlet.
4) Place the machine on the glass and position drill over desired hole location.
5) Lock suction cup holders by applying gentle downward pressure; flip levers down.
6) Place the retaining ring on the glass under the diamond drill.
7) Adjust the coolant valve until you have desired water/coolant flow.

8) Turn on the main switch on the control box.
9) Set the correct speed by turning the speed dial. (For faster speeds, turn clockwise.)
10) Begin drilling by lowering the up-down handle. Use constant pressure. Occasional up and down strokes
can help clear the hole of glass swarf.
Lighten pressure at the end of cut to reduce backside chipping.
11) When hole is completed, gently lift handle to get a smooth finish.
12) Turn off machine, lift the vacuum cup levers, and remove machine.
13) Verify glass core has been ejected from drill bit.
14) Repeat process as needed.
15) Unplug machine from the power supply and clean off any glass/water residue.
ROUTINE MAINTAINANCE
Your AMZ1 Diamond Drilling Machine is designed and built to give you extended service. Drilling of glass
presents tough operating conditions due to the abrasive nature of ground glass particles and the damp
environment of wet drilling. Great benefits can be received by a quick cleanup with a clean rag after each use.
The fresh damp glass slurry will wipe off easily. Left on the machine to dry, it will build up and harden.
This same problem can occur on your drill bits. When the glass swarf hardens inside the drill bit, the next time
you use it, this hard material inside the drill bit could prevent you from drilling a hole! Take the short time it
takes to rinse, dry, and lightly oil your drill bits after each use. Be sure to include the thread and taper of the
drill in this cleanup process. We recommend CRL Cat. No. 1200 Metal Lube for all lubrication maintenance of
the AMZ1.
A light coat of oil should also be wiped on the female thread and taper of the spindle. This area is subjected to
constant wet use. Failure to clean up will cause rusting, resulting in threading problems and poor seating of
-diamond drills.
Occasionally put a light coating of oil on the twin posts your machine travels on. Lower the handle to have
access to these posts. A clean rag with light oil can be used on the entire machine to prevent corrosion.
Pay special attention to the rubber cups located on the bottom of the machine. Clean these after each use with a
clean cloth to remove the abrasive ground glass. Failure to do this will result in scratched glass or loss of
vacuum pressure and holding strength. Cup life can be extended by occasionally wiping cup surfaces with
Technical Glycerine, CRL Cat. No. GL22.
After extended use, the motor brushes may need to be replaced. These are externally serviceable for
convenience and available as a replacement part. If your machine fails to start, check the 10-amp fuse located
on the rear of the machine.
When not using your machine, store in a clean dry place.
DIAMOND DRILLS
This machine is designed to be used CRL Belgian-threaded Mount Multi-layer Drills. The mount uses a male
thread on the drill bit and female thread on the spindle to pull matching tapers together. This design assures the
tool will be true running. You can use our PDT Series Metal Bond Drills or our HBT Electroformed Drills. The
machine will accept drill sizes from 1/8" to 4" (3mm to 102mm). You may also use CRL Threaded
Countersinks and Spot Facers in this machine.

COOLANT
Always use proper coolant with your AMZ1 Drilling Machine. Coolant extends the life of your drill bits and
-prevents corrosion within the drilling machine. We recommend CRL Diamond Tool Coolant Cat. No.
DTC80GL to provide optimum cooling and lubricating performance. CRL Diamond Tool Coolant is sold in
concentrated form and is diluted with water in a ratio of 50 parts water to one part concentrated coolant.
Delivery of water/coolant solution is provided by an optional Pressure Tank Assembly, CRL Cat. No. PTA.
CRL DIAMOND DRILL SHARPENING STONES
Extend the life of your drill bits by occasionally dressing them, using our CRL Sharpening Stones. For use on
multi-layer drills, the sharpening stones expose fresh crystal for prolonged drill life and aggressive cutting
action. Always fully saturate stone with water before use. Hold or block stone securely for safety.
DRILL DIAMETER SHARPENING STONE SIZE CRL CAT. NO.

CRL Metal Bond Diamond Drills
CRL Metal Bond Diamond Drills can be used in portable machines and are especially suited for high production -equipment with
water coolant chucks such as double opposed drilling machines. Metal bond drills offer the greatest life of all type glass drills. The
quality of CRL Metal Bond Diamond Drills is the finest -available and have a 3/8" deep cutting matrix filled with -diamonds and
bronze bond that are more fragile than plated drills. Because of this they should always be used in true-- -running machines on flat
glass -surfaces. Use a wet -sharpening stone to expose fresh diamonds when drilling actions slows.
CRL Electro Formed Diamond Drills
CRL Electro Formed Diamond Drills are thin walled with 1/2" deep multi-layer of -diamonds and bonding matrix designed for high
speed, high production drilling.
The Fragile nature of this type of drill requires use in a precision machine such as our AMZ1.
Sharpening of these drills as required will keep up top speed production.
CRL Belgian Style Diamond Countersinks
These Belgian Style Diamond Countersinks are made with the metal bond diamond process. A groove in the head feeds water to the
countersink face. The 90° angle is perfect for putting a chamfer on holes in glass.
CRL
Diamond Spot Facers
