17PCS Rotary Hammer & Chisels Masonry Drill Bit Set, SDS Plus Drill Bits Set, Fit for Drilling and Cutting in Concrete,Brick,Walls

I usually don't leave reviews, but this set of drill bits seems to be legit. They're marked in millimeters instead of fractions, but that is easy to convert. They're priced good ( June 2022) and they drill thru concrete like they're made for it. Some of the smaller diameter bits are a little too small. Even the equivalent to half inch is bearly 7 inches long. But over all really good dealExtended Review. A quarter of an inch is 6.3 millimeters and the closes bit to that is 6 millimeters. It was extremely difficult to drill a 1/4 inch tap con into a smaller diameter than it was designed for. Had to do some side drilling to make the hole bigger. Still think the bit set is a good deal

This is a really great set of hammer drill bits and attachments.

Items are ok

I wasn't expecting much for bit that are so inexpensive, but I am blown away. I used it for demo of brick wall, chimney, and many holes

Me agrado...

This are great for cement or other materials similar to it, I used this to drill a hole to place new gate rails and they work fine didn't break or a chip of damage, totally worth the purchase.

Worked excellent on my home project! Would buy from again due to great results. Durable!

One of the bits was bent right out the box could not use it. Overall not bad.

Me dedico a mantenimiento y son muy útiles ademas viene en estuche muy completo gracias
