Excellent quality: power tool parts and accessories

I bought three of these. My mason swears by it. He especially likes the durability. He tells me that he makes 80 holes per bit in hard reinforced concrete. Only one other brand fits but is not available. My team always asks about DeWalt tools and supplies. You like performance and reliability.

  • Easy to use
  • Negative impression

Not a substitute for rotary hammer

There is no substitute for having the right tool for the job. I drilled through the bricks and wallboard to install garage lights in front of my daughter's garage. And the 16" length provides a continuous point through 4" brick and then 6" wall. . With a hole large enough for 12/3 Romex wire for power.

  • Absolutely amazing!
  • Nothing

DeWalt DULLS for drills

Carbide drills wear only a few inches on the stone. Why make an 18" bit if you can't use a 2" or 3" bit? Tried to sharpen them - to no avail. Not suitable for softer rock. Might be ok on concrete but a waste of $$$$ on Flagstone and other softer stones I use. For me there is no more De Walt. A long time ago they were good, but apparently those days are over.

  • Good product for the price
  • Something different

Heavy Duty Power Tool Parts & Accessories

I don't think I could break this if I tried. It cut into my base very well. The end that goes into the drill is obviously designed for a pro-level impact drill, and the notches cause it to be off-center in a standard chuck. I cut the end off entirely leaving a smooth shank to grip my chuck and this is now the perfect standard masonry bit. Love it!

  • Great for a small home
  • Compatibility

Fantastic value for drilling holes in the pool wall with a hammer drill

Works better than expected. I drilled a small shallow hole in the wall. My 1/2" hammer drill quickly punched through a 14" poured shotcrete wall. The blow also went around the rebar in the wall. The beat was still sharp after work. Installing the pipe through this hole requires pipe less than 1/2 inch in diameter. I used PE tubing for my wires, but copper tubing would work well for plumbing.

  • GOLS certified
  • Slightly dented

Great drill for drilling deep holes in concrete!

This carbide hammer is just what I need to drill deep holes in concrete. The shaft is very well made and hardly wobbles. After drilling many holes close together and heating the drill, the carbide tip was not damaged. I was very happy with it and I hope it lasts a long time. It also does a great job of getting all the dust out of the hole, saving time pulling the bit back and forth. The roundness of all holes was excellent (as long as I was drilling). Highly recommend and will buy again!

  • This is amazing
  • Almost never

I like using SDS four head bits

I like using SDS four head bits, they are easier to control when opening a hole, round the hole and cut rebar better. The problem with this is that in a month (probably 200 holes) the carbide head fell off on two bits at a time. I only experienced this once with a Hiliti racquet a few years ago and the rep I asked about it gave me some kind of nonsense explanation of how to do it once it's worn out to prevent that smaller holes appear. I usually use Hiliti bits or other lesser known German bits

  • great product

DeWalt SDS 1/2 " x 18 " bit

Just received so can't comment on durability yet. If I understand the expression "elongated tetrahedral helix" to mean that the cutting tip is in the shape of a plus sign (+), then the description is incorrect. The one I received has a standard two groove design. The accompanying note on the packaging states that it is guaranteed for life against breakage through to complete wear and tear. It's rare to get a guarantee on a tool that has to cut the toughest of materials. Considering the price…

  • CARBIDE tip for longer bit life
  • Not sure

Carbide tip broken into granite

I bought this to drill some holes in granite rock. The drill has performed well drilling approximately 9 holes along the full length of the drill. Then I noticed a rebound on the last hole. I pulled the chisel out and then found that the carbide head had been lost in the rock and the chisel was getting very hot. Not sure if I broke it or got a bad one. I ordered another one along with a Bosch counterpart so I can do a comparison. The only thing that I think could have caused it to fail is that…

  • Strong core: SDS Max chisels have a tapered core for strength and maximum durability, especially when drilling deep holes
  • Some small things
