Gunsmithing milling factory glock slide

[chaser_2332]

i offered up my glock 35 slide to a machine shop friend of mine who wanted to add some lightening cuts in the slide. He works in a nice shop with some large equipment and can turn out some nice work. When they dropped a very new carbide bit on the slide it wanted no part of milling a cut. Is there a special bit or something i need to know to make this go better. It seamed to barely go through the finish.

The slide finish "tennifer" is SBN'd, which has effectively a case of around 65Rc so once you get through that (about 0.003") it should be much easier to cut.

You sure it was really carbide? They cut fine with carbide or TiN coated tooling.

Just going by what they said, I was just there watching.

I don't know much about machining, but have small Enco mill and cut a Glock slide with PTG carbide end mills. It was obviously pretty hard, but I didn't have any trouble ..... just a bit of a pucker factor cutting on something I never tried before and heard so much about.

Thanks, maybe the guy just had a brainfart and didn't have carbide

carbide cuts right through it like nothing been doing all kinds of lightening and porting on glocks

Is there a GOOD reason to hack up a perfectly good slide?

Installing a red dot.
