If it walks like a duck....
- Carnoustie, Scotland
I need more storge space. Er32 collets are taking a whole draw...
Test, of what was a spade bit, ground a taper. Cut very well but its a bit small so need to do another.
If the angle of the taper is correct could you not just grind a bit off the bottom so that it matches the Dia of bottom of the collet?
