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 on the
power drive unit may result in serious injury.
6.1 SELECT A TOOL BIT
CAUTION
CAUTION: Use of dull or improperly designed 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 voids the TRI TOOL Inc.
factory warranty.
Select Tool Bit according to the tubing material, the tubing size, and how critical a
near burr free end is.
Use standard entrance angle Tool Bit for carbon steel.
•
These Tool Bits also work well with some stainless steel applications if a near
burr free end is not a critical requirement.
Use a high entrance angel Tool Bit for most stainless steels.
•
Generally this is the most suitable edge geometry for about 90 % of all of the
stainless steel tubing applications.
Use an extra hook angle Tool Bit for stainless steels which are very soft.
•
These stainless steels include materials like 316L, which have been bright
hydrogen annealed, vacuum annealed or annealed and electro-polished.
•
Electro-polished stainless steel has a micro-thin surface, which is high in Cr
and Ni which makes it very soft, but tough and difficult to cut without a burr.
Use a .969” (24.6 mm) tall Tool Bit for 3/16” (4.7 mm) diameter or less tubing.
•
The tall Tool Bit may provide some advantages for wall thicknesses less than
.020” (.5 mm).
• The tall Tool Bit will cut very close to the Collet face, which minimizes flexing
of the tubing from the cutting pressure.
•
The tall Tool Bit will require more time to adjust the tubing position for cutting
and there is some risk of crashing the Tool Bit into the Collet on larger OD
tubing.
