10mm/0.4inch Diameter Carbide Tipped Masonry Impact Concrete Drill Bit SDS-Plus Rotary Hammer Bit 150mm/5.9inch Long

Excellent quality should last a long time.

Affordable and gets the job done very well. I only needed to drill a couple of 3 inch holes, but the bit seems very durable and could have handled a few more.

Drilling in concrete is very difficult. These bits held up fairly well, but I had to drill 4" down in 40+ year old concrete. I bought 4 bits to drill 8 holes and I used 3 of them. For the price, I considered the bits to be a good value. All concrete bits dull and these are no exception. But they cost less than the ones at Lowes and Home Depot.

Drilled 4 holes into the concrete slab . It took minutes and I had 4 nice clean holes

Drilled 16 holes to anchor a gazebo to a cement pad and got the job done, so 5 stars from me.

Using this for drilling holes in cinderblock/concrete to hang some things. This bit, along with a hammer drill, has made quick work of drilling the holes. Definitely would recommend.

I bought this bit thinking it would work in my regular drill but it but it did not. The bit had grooves to fit a hammer drill and doesn’t fit properly in any other drill. A neighbor loaned me a hammer drill and it worked perfectly in that

Great for drilling in concrete.
