toolant Concrete Drill Bit Set & Masonry Drill Bit Set, Shockproof Hex Shank Drill Bit Set (7pcs) for Glass/Brick/Plastic/Cement/Tile, Industrial Strength Carbide Drill Bit Tip, 5/32"-3/8" Box of 7

Got these to use in my impact driver when I don't want (or can't) use my hammer drill. Works well for making holes for fasteners, and lasts for at least a dozen holes without becoming too dull.

Does the job well. I did not think I would need such a long bit. But I like it now.

This a great set of drills. Drilled a clean hole with no chipping. The whole set cost less than a 1/2 " bir.

I had to drill 32, 4 inch deep holes so I ordered two packs. Well, I'm glad I did because at least five out of the 10 in each pack did not cut through the masonry very well. However, the ones that did, cut right through the masonry like butter and I was able to use them again and again. So in a nutshell, if you think you will need more than five of these drill bits, be sure to order two packs.

As descripted. Great quality and drill fit perfect

These concrete drill bits worked really well!!!! They worked better than some other name brand drills that I had purchased, got my project done.

Great quality at good price

I purchased for a handrail project mounted onto tile wall. I used a liberal amount of water to keep bits cool and drill slowly. I had to drill about 10 holes and broke 3 of the bits in the process. These bits are junk. One bit broke within a second or two of drilling. I should have spent the money and bought the Bosch brand.
