I've ordered a boring bar that accepts square and round toolbit blanks (holding them at either 45 or 90 degrees) to allow me to complete internal boring of cylinders. I want to insert short portions of standard toolbit blanks but have never attempted to cut thru one. I suspect a zip disc will do for the 1/8" bits but how do you guys cut 1/4" bits (without ruining the hardness/temper)?
None of the reference literature I've collected seems to address this issue.
Thanks
