Sounds good to me. I was going to say I'll have 3 but didn't want to sound greedy :lol: I can buy them today - no doubt they will take forever to arrive. They shouldn't cost much to post. There's also 25mm long for £4 more ... not sure which to get as the 22mm will be stronger, but 25mm might be useful...

If it snapped twice, back off a bit on cut, 100% of depth per diameter is a bit much on 6mm.

Ok then, I've just checked the Gcode and it was actually 5mm per pass, not 6mm as I thought. I'll try less next time.
I was using 2500mm/min and 18,000rpm ... that makes the chip load very low which I suspect was what caused it to break. It broke when I lowered the feedrate to 2000mm/min. I think I'll try something like lower rpm but keep the same feed next time to reduce the heat.
