Who's used an annular cutter on their mill?

[Flying A]

Will an end mill holder, R8, hold these annular cutters and not spin?

Yes it will work! I used one where I cut the tapered face off till the cutter lined up with the set screw. Worked great,holders are cheaper

Good to hear. The annular cutters I would like to use are 3/4" shanked with two flats. Theoretically, it should work fine.
A sliding fit for the tool shank and two counter-bored set screws.

Thanks to Alan I now have the same holder he got for use in the lathe. I was going to order the R8 holder also for the mill but Alan "convinced" it wasn't needed. I'll just hold them in my ER40 collet chuck or use the R8 to MT3 adapter if that doesn't work out for some reason.

Gotta love Amazon. Added the holder to an oder I was placing early this morning. Received the order the same day today, and best of all on a Sunday. Not my first order like this but it's really awesome.

Can you hold these in a 3/4 inch r8 collet? ?? Anyone ever try it ????

 

[Hawkeye]

I use my 3/4" shank annulars in a 3/4" tailstock chuck. It holds them tightly, so I'd expect a collet to work well, especially if the ridge between the flats is against a solid segment of the collet.

Would one of these work 3/4 endmill holder guess I could always drill and tap the other side to add another set screw

I'm sure it would work but if you have a R8 x 3/4" I'm not sure why you would want to buy a holder with set screws. If I didn't have a 3/4" collet I would order one.

Ok
Wow
I like that cutter . I never have used any of those
I think it would work good on thin metal

Yes they do. I have a 30 mm for providing holes for push buttons. It's absolutely necessary to clamp or otherwise secure thin stock if the cutter has no pilot.

Sometimes it gets very congested with the table cranked up. This R-8 weldon adaptor would be a nice addition for those awkward pieces requiring a larger precise hole.

I'm confused as how inserting the annular cutter directly into the collet would increase congestion. One 3/4" R8 collet would accept any of the annular cutters from many different manufactures and the length of the cutter extending from the end of the collet would be a maximum of 4" with a cutter designed for 3" depth of cut. Yes the holder would work but why would I want to purchase an end mill holder when the R8 collet will do the job? I'm aware of the pros and cons or opinions of using a solid holder vs a collet when addressing end mill creap, but the cutter isn't an end mill, it's designed for drilling fast accurate holes.

Edit; In reading your comment again, are you referring to workpiece conjestion or ability to reach far enough, close enough, etc. without the quill interfering?
