DEWALTDW5230 3/8-Inch x 6-Inch Carbide Hammer Drill Bit , Silver

Product shipped in one day and worked like a charm. Cut through block wall really easily and made 4 holes in just a couple minutes. I have used other bits on this wall and struggled to get the job done before drill bit dulled.

Drill bit worked great. Used to drill into concrete steps to install railing. Still sharp after 8 holes drilled. No breakage.

There's a hole in the wall now where there wasn't one before.

Used to install wrought iron railing on a cement porch

Great price and just as described

Durable enough to drill through cement steps Happybuy Wrought Iron Handrail 1ft for steadiness for sliding glass doors on windy days

Works great in concrete. Good design for removing dust out of hole.

This bit was used to drill anchor points in block patio for a pergola. 16 holes and still going strong.I would buy this one again.

The bit is probably excellent but was wrong for my hammer drill.

I had spent day's of effort in trying to make 3/8 hole in my apartments concrete cement wall. I was even denied by task rabbit guys that they can't do hard concrete cement walls.As a techie and hobbyist who do all home jobs himself; I researched solution and arrived at this page for getting carbide tipped drill bit; after wasting time n effort n getting stressed out with not good enough drill n various type of drill bits including masonry bits, all useless, don't waste your time. If you need to hang heavy loads; for me my big n heavy TV Wall stand which takes load of my heavy TV (old HD 55inch comparatively heavier than new ones). I bought this one to go with corded 7.5amp good enough drill and voila I was able to finish 6 holes and hang my TV stand n TV within an hr. With accurate measurements n alignments. Drilling holes is a breeze with this one. Highly recommended for DIYers.....

Drilled pilot hole for a lag bolt in my basement floor, worked great even with the regular drill. Ended up being the wrong size (my fault) so I can't attent to durability

What you looking for

I used to drill 1 1/2'' holes into the bricks, when it got to the 5th one not good anymore even I poured the water when drilled. Disappointed.
