SAFETY PRECAUTIONS
IN GENERAL
When using rotating head cutting equipment, basic safety precautions should always
be followed to reduce the risk of personal injury.
Operate this tool only in accordance with specific operating instructions.
Do not override the deadman switch on the power unit. Locking down, ob-
WARNING:
DRESS CONSIDERATIONS
structing, or in any way defeating the deadman switch on the power drive unit
may result in serious injury.
Model CBM-3 Counterbore Module
Use standard safety equipment. Hard hats, safety shoes, safety harnesses, protective clothes, and other safety devices should always be used when appropriate.
Use safety glasses. Do not operate cutting tools without eye protection.
Dress properly. Do not wear loose clothing or jewelry. They can be caught in rotating and moving parts. Avoid slippery floors or wear nonskid footwear. If you have
long hair, wear protective hair covering to contain it.
WORK AREA
Keep the work area clean. Cluttered work areas and benches invite injuries.
Consider the work area environment. Keep the area well lit. Keep electrical cords,
cables, rags, rigging straps, etc. clear of rotating equipment. Do not use powercutting tools in the presence of flammable liquids and gasses.
Keep visitors away. Do not let visitors or untrained personnel at or near operating
tools. Enforce eye protection requirements for all observers.
Do not over reach. Keep proper footing at all times.
Stay alert. Watch what you are doing. Use common sense. Do not operate tools
when you are tired.

TOOL CARE
Maintain tools with care. Keep tools in good operating condition. Sharp tool bits
perform better and safer than dull tool bits. Well maintained tools function properly
when needed.
Check for damaged parts. If a tool has malfunctioned, been dropped or hit, it must
be checked for damage. Run no-load tests and feed function checks. Do a complete visual inspection.
Electric motors. Use only with proper AC voltage power sources and observe all
normal electric shock hazard procedures.
Do not abuse power and control cords. Pulling or running over cords and cables
can result in electrical shock hazards and malfunctions. Keep control and power
cords out of all cutting fluids and water.
Hydraulic drives. Observe proper procedures for electrically driven power sources.
Avoid damage to hydraulic lines. Keep quick-disconnects clean. Grit contamination
causes malfunctions.
Air tools. Check the exhaust muffler. Broken or damaged mufflers can restrict air
flow or cause excessive noise. Use air motors only with a filtered, lubricated and
regulated air supply. Dirty air, low-pressure air or over pressure air will cause malfunctions, including delayed starting.
AREA EQUIPMENT
Secure work. Whenever possible use clamps, vises, chains and straps to secure
pipe.
Make sure the tool is secured; it is safer to have both hands free to operate the tool.
TOOL USE
Use the right tool and tool bit for the job. Do not use a tool, which is incorrect for the
job you are doing.
Keep the tool bits fully engaged in the tool bit holders. Loose bits are a safety hazard.

Model CBM-3 Counterbore Module
Disconnect power supply during setup and maintenance. Use all ‘Stop’ or Shut off’
features available when changing or adjusting tool bits, maintaining the tool, or when
the tool is not in use.
Remove adjusting keys and wrenches before applying power to the equipment.
Develop a habit of checking the tool before turning it on to make sure that all keys
and wrenches have been removed.
Do not force tools. Tools and tool bits function better and safer when used at the
feed and speed rate for which they were designed.
Do not reach into rotating equipment. Do not reach into the rotating head stock to
clear chips, to make adjustments, or to check surface finish. A machine designed to
cut steel will not stop for a hand or an arm.
Handle chips with care. Chips have very sharp edges and are hot. Do not try to pull
chips apart with bare hands; they are very tough.
Avoid unintentional starts. Do not carry or handle tools with your hand on the operating switches or levers. Do not lay the tool down in a manner that will start the
drive. Do not allow the tool to flip around or move when adjusting or changing tool
bits.
Store idle tools properly. Disconnect tools from the power source and store in a safe
place. Remove tool bits for safe handling of the tool.

GENERAL DESCRIPTION
The Model CBM-3 Counterboring Module Kit is a mechanical accessory for the
Models 616SB through 636SB Clamshells and for the Models 614RBL through
636RBL Clamshells.
The Model CBM-3 provides the capability to counterbore pipe after an in-line spool,
valve or fitting has been removed.
The Model CBM-3 is mounted directly to the Tool Block via the appropriate Adapter
Plate.
No repositioning or modification of the Clamshell is necessary after the in-line
spool has been removed.
The Model CBM-3 features a manual “easy grip” axial feed and infinitely adjustable
radial positioning.
The Model CBM-3 utilizes form Tool Bits that are available in various standard configurations.

MAINTENANCE
All components should be cleaned and coated with a light film of oil prior to storage.
When the Counterbore Module is operated in such a way that the Module collects
chips or debris near the Tool Holder, the Counterbore Module should be cleaned
after each cutting operation.
Wipe the unit down and spray with rust preventative under severe humidity conditions.
Visually inspect for loose Screws, missing Bolts, or damage due to impact.
Contact TRI TOOL INC. if major repair is required.
Tighten or replace Screws or other parts as required.
MONTHLY
Thoroughly clean and lubricate the Feed Tube and Boring Bar.
Feed the Boring Bar out of the Feed Tube.
With a clean, dry rag, thoroughly wipe down the Boring Bar and the Feed
Tube.
Be sure that all of the old lubrication, chips, and dirt are completely removed.
Lubricate the Feed Tube, Feed Nut, and Boring Bar with a light machine oil.
Reassemble the Boring Bar into the Feed Tube.

OPERATION
Read the operating instructions carefully before attempting to operate the Model
CBM-3 Counterbore Module.
Always wear adequate eye protection when operating power tools.
INSTALLATION
Remove the five (5) Cap Screws from the front of the Tool Holder on the 600SB or
600RBL Clamshell.
Installing the Counterbore Module onto a Tool Holder
10
Place the Adapter Plate (P/N 24-0634 for the SB’s or P/N 24-1281 for the RBL’s) on
the top of the Tool Holder and tighten it down with the longer Cap Screws (P/N 330066 for the SB’s or P/N 33-0081 for the RBL’s).
Place the Support block and Counterbore Assembly on top of the Adapter Plate and
tighten these down with the Cap Screws (P/N 33-0079).
Place the Counterbore Tool Bit in the Tool Holder Slot on the Boring Bar and tighten
it by using the Set Screws on the side of the slot.
92-0227 : Rev. 070529
Page 11
Model CBM-3 Counterbore Module
The Tool Bit to be installed should always provide a 1/4” (6 mm) minimum chip
clearance against the Tool Holder.
Loosen the Clamping Screws and slide the Sleeve Assembly in toward the pipe until
the Tool Bit Shaft is just outside of the pipe face.
Adjust the position of the Tool Bit to the pipe bore by using a combination of:
Control Features
The different hole patterns provided on the Support Block.
The radial feed mechanism of the Tool Block.
Positioning the Tool Bit in the Tool Bit slot.
The Tool Bit should not be extended out of the Tool Bit slot by more than 5/8” (15.9
mm) on the cutting side of the Tool Bit Holder.
Lock the Feed Tube into position with the Clamping Screw.
Check to insure that the Tool Bit is clear of the pipe and that the Feed Pin is retracted.
OPERATION
Slowly rotate the Clamshell to insure that the Counterbore Tool Bit clears the pipe.
Increase the Clamshell RPM to cutting speed. Reference the “Cutting Speeds and
Feed” section of this manual.

To feed the Tool Bit in, hold the Feed Knob.
Do not use a wrench or lever to obtain extra holding strength.
Do not force the feed, if the feed pressure builds up too high, release the Knob for 2
or 3 revolutions.
NOTE:
For a lighter feed rate, hold and release the Feed Knob as the Clamshell revolves.
The feed rate is .010” (.25 mm) per revolution, if the Feed Knob is held continuously.
