Just to clarify -"with 5 or so collets I can handle plain or threaded

least) metric 6mm, 10mm, 16mm, 20mm and 25mm and imperial ones i.e 3/8
fits in a 10mm collet.

Bill thanks for the reply - I was wrong about the 3/4 slot drill ( did
the conversion in my head and it came out wrong) 3/4 is less than 25mm
- anyway I have two new cutters that have a 25mm shank.

Curious as to how you handle 12 mm shank cutters?
