Faceplate on my big lathe (D1-6 mount) - first use. 

Thanks Paul.

Annular cutters would have been perfect for this job but I only have a small set ~14 -24mm. Sadly, the larger sizes are very expensive eg 60mm ~$150 and I can't justify that cost for my very occasional use. I was a bit surprised that the hole saw did so poorly as I have used hole saws in this way before with no problem: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2oGaQTjMz68.html Anyway, thanks for your comment.

@@alanshomeworkshop I love them, mine are all non metric, up to 2'' i got them cheap, they sure do get a good hole to start with, but you're right, good Hole Saws work well as well.

Well I did consider the possibility of such an issue, but naively thought 400rpm would be ok. However, I'll take note of your advice and use the milling machine if there is a next time. Thanks for your comment.

They're actually a lot stronger then you give credit, they're made to be dropped and banged around.

@@65cj55 yeah dropped and banged around is one thing being spun is a whole other thing go have a look at fly wheels exploding and the damage they do by all means 400rpm isn't a lot but it's also not a high quality casting or forged balanced and precision machined peice of equipment

@@alanshomeworkshop I don't know if you have seen the aftermath of fly wheels exploding obviously it's not spinning at stupidly high rpm but still having it clamped down and that the clamps where putting a side load onto it increased the potential danger similar to using the side of a grinding wheel At least in the mill you can spin the tool at the right rpm to make a good clean cut with no risk of a catastrophic failure Im a safety 3rd kinda person oh&s gets in the way of progress but I'd hate to see or hear of you getting hurt or seriously injured

@@TheConkulator They're ample strong enough, likely just as strong as the Faceplate.
