I needed a longish bit to drill through field rock in order to properly "weaken" the stone to break it into the rough shape I require for various stones. The bit simply wont dull and I cannot think of any harder test to run a bit through in order to attempt to dull one. This one has held up for a couple of months so far using only water on occasion as a lubricant. Great drill bit of the highest quality. I couldnt ask for more and expected a lot less than the perfection I recieved!!

I bought this drill bit do drill drop in anchors into concrete.... this bit is simply awesome. IT totally beat out the BOSCH Blue bits by far.... it has a better carbide drill head to it and it lasts much more than the bosch bits. i'm not saying the bosch bits are bad.... but this dewalt bit had more flex to it and drilled much faster and sayed sharper longer.... plus it was a few dollars cheaper via amazon prime !!

We abused this one for quite a long time, I was expecting it to die much faster, but it served us about 3 times longer vs expected...

These are the last of the German-made masonry drill bits. Bosch has gone to China and DEWALT, too, on their sets. If you aren't using an SDS hammer, the individual DEWALT bits are the last line of German-manufactured hammer bits.

Sure thought it would work.

Just trying to bore a 1/2 inch hole in my basement floor for an RF ground rod. EZPZ, right?

First I tried a star-chisel, which I've used before and had very good luck. Tap-tap-tap. Bent the thing. Sent it back.

Tried this bit. I'm at 4" and it just won't go any deeper. Using a good quality hammer drill, I've used the smaller blue cobalt bits before with some good effect, but this thing just will not bore any farther into the concrete.

House was built in 1971, I have NO idea how thick the pour is. Local contractors tell me it shouldn't be any deeper than 4 inches - they say they've seen them as thin as 2", a good friend of mine did some serious damage to his basement slab stacking ammo boxes, but that's another story for another review sometime - what kind of gravel did they use back then anyway, diorite, granite, diamond??

No, it's not rebar I'm hitting. Dropped a magnet probe into the hole several times, it's not sticking or pulling.

On to the Bosch bit at 5 times the cost? Probably. In for a penny, in for a pound. I'll save this for the day I need to drill through cinder blocks. If that doesn't work, I know an AP 308 round will.

Just didn't work for me. YMMV.

I bought this to use with my Mikita 18V hammer drill. I laid several new cement supports and needed a bit to bore a hole in them to insert cement anchors to attach post supports. This bit bored through the six supports with no problem whatsoever. It was like using a butter knife, smooth and easy. Highly recommend!

This is a great drill bit. I also have a Bosch 1/2 inch carbide bit for masonry that is 8 inches long and this Dewalt seems to work a little better. I use them in a Milwaukee M18 fuel hammer drill and neither slipped at all, both worked well but the Dewalt seems like it worked a little faster. They both did a good job of moving the dust out of the hole as I drilled.

Dynamite - Got through cinderblocks in seconds. I was running wire to my shed as well as the satellite dish feed and this bit killed it. Still sharp after the job, this will find a place in my tool chest for a long while.
