Erie Tools5 Piece 24" SDS Masonry Drill Bit Set fits Milwaukee Hilti Bosch Tungsten Carbide Tip 3/8", 1/2", 5/8", 7/8" & 1"

I do lots of electrical work in old apartments and for the thick walls these bits are awesome.

Not much to it. They work well for what they’re designed to do. I used these to make holes for conduit through brick with a ryobi 18v sds plus drill. Drilled through like butter

Great price and they cut quickly though brick I recomend these to anyone that is an installer

It works. Will not last long of you have many holes on tough walls. It's more of a one time or a few times you need it cause of the length. But not my everyday go too. I get a Milwaukee 5x or Bosch 5x bit but if I need longer than 18" I start with the good bit and finish with this. You need to realize cheap needs more TLC than the sturdier more expensive bits.

Good tungsten carbide is cheap and easy to make, maybe the one thing you can trust from China.

It was good using it at work.

Ordered to drill holes through an 16” adobe wall. Used all drills from small to large sequentially. Very good quality.

Liked the length, used them to drill through 22" of concrete to mount frame for exhaust unit on the wall of a restaurant in Atlanta.
