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 specic 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-2, 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 rotat-
ing and moving parts. Avoid slippery oors or wear nonskid footwear. If you have
long hair, wear protective hair covering to contain it.
WORK AREA
Keep the work area clean. Keep the area well lit. Keep electrical cords, cables,
rags, rigging straps, and etc. clear of rotating equipment. Do not use power-cutting
tools in the presence of ammable 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 uids 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 mufer. Broken or damaged mufers can restrict air
ow or cause excessive noise. Use air motors only with a ltered, 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-2, 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 nish. 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 your 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 ip 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 C’bore Module Kit is a mechanical accessory for the Model 604SB through
612SB Clamshell.
The C’bore Module provides the capability to counterbore pipe after an in-line spool,
valve or tting has been removed.
The C’bore Module is mounted directly to the Clamshell.
No repositioning or modication of the Clamshell is necessary after the in-line spool
has been removed.
The C’bore Module features a manual “easy grip” axial feed and innitely adjustable
radial positioning.
The C’bore Module uses Form Tooling Tool Bits that are available in various
standard congurations.

MAINTENANCE
All components should be cleaned and coated with a light lm of oil prior to storage.
Use a clean, non-detergent oil, preferable SAE 10 (90 SSU or lighter) or oil which is
specied for the air motor.
If the C’bore Module is operated in such a way that the Module collects chips
or debris near the tool holder, the C’bore 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.
Tighten or replace screws or other parts as required.
Contact Tri Tool Inc. if a major repair is required.
MONTHLY
Thoroughly clean and lubricate the Feed Screw and the Boring Bar.
Feed the Boring Bar out of the Tool Bracket.
With a clean, dry rag, thoroughly wipe down the Boring Bar and the Feed Screw. Be
sure that all old lubrication, chips, and dirt are completely removed.
Lubricate the Feed Screw and Boring Bar with a light machine oil.
Reassemble the Boring Bar into the Tool Bracket.

OPERATION
CONFIGURING THE COUNTERBORE MODULE
Select the appropriate Tool Bit. Refer to the ‘Tool Bits' section.
Use of dull or improperly designed Tool Bits or Tool Bits not manufactured by
WARNING:
Install the Tool Bit in the Boring Bar. Be sure the cutting edge lies along the radial
centerline in the direction of rotation.
Adjust the counterbore diameter.
Radially adjust the Feed Tube using the Feed Sprocket.
Tri Tool Inc. may result in poor performance and may constitute abuse of this
machine and therefore voids the Tri Tool Inc. factory warranty.
MACHINING SEQUENCE
Check to insure that the Tool Bits are clear of the pipe and that the Clamshell Feed
Pin is retracted.
10
Slowly rotate the clamshell to insure that the Form Tooling Bit clears the pipe.
Increase the Clamshell RPM to cutting speed. Refer to the section on ‘Cutting
Speeds’.
To feed the Tool Bit in, hold the Feed Knob.

WARNING:
WARNING:
When the counterbore is nished, release the Feed Knob and allow the Clamshell to
rotate 2 or 3 times to release the chip.
Retract the Tool Bit.
Remove the C’bore Module from the Clamshell.
Remove the Clamshell from the pipe as described in the appropriate Clamshell
instruction manual.
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
before continuing.
