Thick stubby drills

I use the Rotabroaches in an adapter made to fit the 20mm R8 collet. The short ones are good for about 25mm deep cuts, but need frequent clearing. My adapter adds about 75mm from the collet nose to the broach cutting faces.

Thank you, I think that rotabroach is way to go. I went to buy one 20 mm dia short rotabroach....they had none. Bummer.

Looksl like the rotabroach is the solution.

I use mt3 collet without slipages so far, the largest rotabroach I have is 35mm tct tiped runs between 80 to 120 rpm , depending on the hardness know power coolant just a spray bottle , mag drills run slow a search on the speed should help there .

PekkaNF:
Thank you.

Are generic brands mostly marginal? Are there better brands or should I get two real rotabroatches (mostly need 20 and 24 mm) or buy something like this:

Now idea on brands most of mine are second hand , it's the grade of material you pay for HSS Cobat or TCT as with all cutting tools you get what you pay for .
