DEWALT SDS+ Hammer Bit, Rock Carbide, 1/2-Inch by 4-Inch by 6-Inch (DW5437)

Worked like a charm. One of the best bit is have used. I made the mistake of using a Hitachi bit and will never do that again. Dewalt bits are worth the accuracy and the ease of use.

Dewalt top quality.

Does the job well, didn't think it would be as tough as it is.

Works great

I bought this DeWalt and the similarly priced Bosch bit for installing wedge bolts in concrete to mount fence cloor flanges. I started with this one, and only realized how much better that the DeWalt worked than the Bosch when I swapped bits as the wear mark on the DeWalt started to fade (about 50 holes in, and a feature not present on the Bosch) and realized that brand new the Bosch did not work quite as well as the worn DeWalt I had just swapped out. Note: this is designed for use in a professional / advanced DIY style SDS / SDS Plus (but not SDS Max) style hammer drill. If you are having trouble getting it to fit in your drill, or find the flutes on the shank are making it difficult to vet it seated, you are not using the sort of drill this is designed for. A regular hammer drill/driver is not the right sort of drill.

Received on-time & as described.

It didn't cut through my cement very well. It took a lot of work. We purchased another bit at Home Depot and it worked much better.

I have used other brands, this one seems extra tough. Based on previous experiance I bought three for the job I had and the first one I used is through the job and and looks like new except for some discoloration of the bit due to heat. Excellent

No funciono porque traen un anclaje diferente y no me di cuenta

Even using a discount brand SDS hammer drill, this bit cut holes through granite as easily as drilling dried oak with a regular bit. It definitely wasn't this easy with the cheap bit I tried before this one!!! I made sure to pour water periodically in the holes while drilling, and kept the bit grooves free of built up rock dust clogs, but that just seemed like common sense.

Cuts through concrete like a hot knife through butter

Excellent drill bit. Using this bit, I was able to successfully drill at least 50 holes, 4 inches deep in concrete including the embedded rocks. No complaints from the bit at all although the guy drilling the holes (me) did his fair share of @&#$%$!&*#@, growling, puffing, and panting. Drilling a large number of holes through concrete is tough work.

Perfect item! Did the job
