I have drilled a few different metal types. For example, I drilled angle iron for a project. Also drilled holes in a "universal" mounting bracket for an ATV 12 v winch. The bracket was not so universal...Typically, I drill a very small hole first, then step up to slightly larger bit, repeat until the hole is the proper size. These bit are more brittle than less hardened bits so they do have a tendency to snap off if they catch the metal you are drilling. And, of course, they work excellent on other materials like wood and plastic.

will this go through thick steal with my M18 Drill/hammer drill (it's a beast?

going through those big steel green dumpsters....
Asked by: sruli
I can't give a definite answer, but I can say I have drilled heavy angle iron up to 1/4 inch. I used the M18 cordless drill not the impact driver. I also drilled small pilot holes first and stepped up to 3/8 inch holes.

cut thru stainless with household cordless drill?

would cutting thru a stainless steel sink be possible with these bits and a plain old cordless drill, or would it require something like a drill press or impact driver?
Asked by: Rr
I think it would. You may want to drill a pilot hole and step up incrementally (depending on how big you're going). And use you're biggest battery, if you have that option.

Is hss-cobalt?

Is hss-cobalt?
Asked by: Rayo
HSS stands for High Speed Steel. Which is a type of high catrbon steel. Cobalt, as I understand it, is a coating like Titanium coated bits. Cobalt bits can cut harder materials than HSS, or Titanium coated bits. I reserve using these bits for harder steels.

Can cobalt drool concrete?

Asked by: Scott
Do not use these on Concrete. The bit will become dull very quickly. Use Masonary bits for that.
