6. OPERATION
DANGER
DANGER: Do not override the deadman switch on the power unit. Locking down,
obstructing, or in any way defeating the deadman switch may result in serious injury.
6.1 Select and Install a Tool Bit
The use of dull tool bits or tool bits not manufactured by TRI TOOL Inc. may
result in poor performance and may constitute abuse of this machine and
therefore void the TRI TOOL Inc. factory warranty.
General guidelines for selecting a tool bit.
Determine the tubing material, tubing size, and how critical is it to have a near
burr free end.
• CARBON STEEL - use a standard entrance angle tool bit. These tool bits
also function well with some stainless steel applications where a near burr
free end is not a critical requirement.
• MOST STAINLESS STEEL - use a high entrance angle tool bit for most
stainless steels. Generally this is the most suitable edge geometry for about
90% of all the stainless steel tubing applications.
• SOFT STAINLESS STEEL- An extra hook angle tool bit is recommended for
soft stainless steel. These stainless steels include materials like 316L, which
have been bright hydrogen annealed, vacuum annealed or annealed and
Electro-polished. Electropolished stainless steel has a micro-thin surface,

cut without a burr.
• EXOTIC ALLOYS - Use the M-42 tool bits when the high heat resistance is
required to avoid burning the cutting edge of the tool bit. M-42 can improve
the life expectancy of the tool bit under some conditions on stainless steel.
M-42 tool bits are more brittle than the standard M-2 tool bits, therefore there
is a much greater risk of damaging the M-42 tool bit when installing the tubing
in the Tube Squaring Machine. Loss of tool bits from damaged edges may
not offset the improved cutting life that those tool bits promised. Some of the
exotic alloys may require tool bits with both the extra hook angle as well as
the M-42 tool steel for heat resistance.

WARNING
WARNING: Check that the Model 301SP is disconnected from the power source
before you install a tool bit.
