Owl Tools SDS Plus 1/2 Inch x 18 Inch Masonry Drill Bit for Rotary Hammers (Industrial Grade Carbide Tipped) Extra Long Perfect for Concrete, Cement, Brick, Stone, and More!

I use SDS bits in my Roto Hammer. This bit had to penetrate a cinder block filled with concrete and steel. Luckily I didn't hit any Steel and it went through the entire cinder block and came out the other side without a big blowout inside the building. This is the one you want to use when you have to drill several holes.

Great drill bit for any use. Seems to be made of good quality to last a decent amount of time under normal use.

Put a hole through the basement wall to run some speaker cable. Make sure you know where you are drilling! And patch any gaps so the mice don’t squirt through.

Not very well made. Kind of light duty. Probably work ok on drilling one hole. Does fit a Bosch sds plus but nothing as rugged as the Bosch concrete drill bit.

Well made and durable. It was used in a standard drill but worked fine

Works create to drill a hole through mortar in my house.

It worked fine for drilling. It has stayed sharp through maybe 100 total feet of concrete.

Did the job with ease. Still in great shape after the job was complete.
