12-PCS Masonry Drill Bit Set & Concrete Drill Bit Set, 1/8 to 1/2 inch Professional Carbide Drill Bits Tip for Glass, Tile, Brick, Cement Concrete Plastic Wood etc. Masonry Drill Bits Set by DYRECELVE

If I could give 6 stars, I would!! It is so hard to find 1/8 and 5/32 masonry drill bits. And, basically impossible to find good ones!! I had several epic fails before I ordered these. They are PHENOMENAL! Super sturdy. They glide through mortar like butter! I cannot say enough good things about these drill bits! I highly, highly recommend them!!One last thing, I used these with a plain old Dewalt rotary drill. Most masonry drill bits require an SDS drill or Hammer drill. Not these! Whew!!

Very good grade. I'm glad I bought these since the bit that came with my cement screws was junk and only lasted 3 holes. I used one bit on about 30 pre drills and it never slowed.

Works great and drilled right through concrete

You can not beat how well these carbide drill bits cut through brick, I was surprised and pleased how well they worked.I have not tried concrete but 5 stars with brick .

Worked perfectly, even with my cheap, low power drill.

Son excelentes y económicos. Los volvería a comprar.

I like to use these on my old plaster walls to prevent them from cracking.

Will come in handy
