Wow! Got my first carbide bit!

[Charlie Mike]

This stuff is AMAZING! Got a Cobra Carbide brand 3/16" fluted and it cuts like butter.

They're worth it. Run em fast and steady, and don't be cheap with the oil/coolant. Just don't put any torque or sideways pressure on them, they break very easily.

With the price of carbide these days, HSS and Cobalt are next to obsolete.

 

[Charlie Mike]

I paid $17 at my B&M.

 

[Fellhoelter]

And with a tad bit of care, you will remove a lot more metal than $17 worth of HSS would do.
And faster too.

I need to buy better clamps cuz the chatter didn't sound good.

You will ruin your carbide bit if you have chatter, or movement of the material you are cutting. Let the steel ribbons flow!!

OK, gonna lay off on that til I get another vice grip.

CM,
Check out this drill press clamp from Delta. I use either this or my super duper Kant-Twist brand clamp. The Kant-Twist is quite a bit pricier though. This Delta model does a really nice job of holding things in place on the drill press.

Ahh, for some reason I was thinking this was an endmill.

Carbide drills have their place, and I have plenty, but for most drill press applications cobalt excels.

You want zero chatter, flex, or movement, AND good technique, or you will be kissing your $17 goodbye.

I use those too.

Grizzly has them too at half the price.

I think it's odd that I can't find vise grip versions of them because it's essentially a modified vise grip.

Thanks Count! I have been looking for those ever since I saw one of Jonny's WIP's

+1 on what Brian said. Most holes in my shop are drilled with screw-machine length cobalt drills. Carbide has its uses - like if you forget to drill a hole before hardening - but absolutely requires rigid clamping.

I always wondered the same thing........to look at it you would swear it was made by Vise Grip. Go figure...

Ryan, you could've asked

2 of those is exactly what I need! Fortunately my FIL is a HF junky. That's where he got my drill press from.
