Thread: Cutters for HM-50

Hi David,
Is it a straight shank or does it step down to 1"?
ER40 goes to 1"

If you can fit it in a chuck, then it will be o.k, your limited in size with the mill by its lowest speed. I think you could get away with a 40mm dia HSS cutter, and about 120-150mm in carbide.

You will have no problems using that with a HM52, it will just be holding it.

yep..NT30 - ER40 collet and holder will do the trick....i think

Yes it steps down to one inch shank threaded on end for a clarkson type collet

Unless you are lucky a second hand 1" clarkson is going to cost more than new ER40. I dont recall seeing a 1" clarkson with a 30 taper on it.(but being as I've likely only seen 2 doz in my life that might not mean much). Thinking about it some more, while the ER collets have worked fine on the small cutters I've used would*, 1 1/8" be asking to much?

*I think 16mm is the biggest cutter I have used in an ER collet and I'm pretty sure that was in wood

Ive used a 32mm carbide insert cutter in an er40 collet now worries.
