Great bits for the corner!

These beats are amazing! I used a drill to drill through this pendant to re-cover it. There were 40 holes in the angle iron and it was still sharp enough to drill more! The steel was hard enough to drive bolts into a hole, it required a punch, so it wasn't a soft metal. I finally threw the first one out yesterday after I drilled 6 more holes in my steel gate to attach a guy rope. I wouldn't even throw it away if I didn't have 9 left!

Pros

FOR METALWORKING – Particularly effective when cutting hard metals (less than 38° HRC) such as stainless steel and cast iron, although they can also be used on softer materials such as copper and aluminium. Not for hardened steel / high carbon steel. Try adjusting the RPM if it's not penetrating.

Cons
