M-42 can improve the life expectancy of the Tool Bit under some conditions
but it should be noted that M-42 Tool Bits are more brittle than the M-2 Tool
Bits. Therefore, there is a much greater risk of damaging the 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 expected from M-42
tool steel.
Tool Bits made from M-42 tool steel with its high heat resistance, may provide
longer life on some exotic alloys. Be aware that the cutting speeds to obtain a
burr FREE end is slower for all tool bits other than the DURABIT Series Bits.
The cost impact of the slower running speeds may not offset the increase in
life expectancy.
Select the tool bit(s) required to machine the end configuration desired.
When performing a tube squaring operation the tool bit may be placed in any
slot.
When performing separate machining operations such as facing or beveling,
the tool bit(s) may be installed in any one of the two cutting head slots.
When performing two machining operations such as facing and beveling, the
tool bits should be installed with one in each slot.
