BOSCH HCK001 7 Piece Carbide-Tipped SDS-plus Rotary Hammer Drill Bit Set with Storage Case

Used one on a hammer drill to break concrete and it worked quite well. Not sure how long they will last but so far so good.

He’s real bits are quality made, and stand up to their name

I used the 1/2 " one to drill ~100 holes in concrete, the drill bit stills works like new. You can't go wrong with these bits.

There's really not too much to say about Bosch bits that hasn't been mentioned already. They perform as they should, and last a good, long time. I purchased this set with my Bosch Bulldog rotary hammer, and have used them a number of times drilling into old, poured concrete floor slabs, and into newer poured concrete walls. In all cases, they have quickly and efficiently performed their task, then returned to looking like new with a quick wipe-down with a rag, and a spray of light oil to protect them during storage. These bits are quite short, the length of the SDS spline can be slightly deceptive if you are not familiar with roto-hammer bits, but they are more than sufficient for setting wall anchors for shelving and soforth where stiffness will benefit you more than reach. I would suggest that anyone buying a rotohammer should pick up this bit set along with it, for the price it will give you a lot of versatility and will last a long time. It's not the be-all end-all of bit sets, but for the price it is very good. Even comes in a nice, slide-top case to keep all the bits sorted out from the rest of the junk in the bottom of the tool box. When I finally manage to wear mine out (haven't even made a significant start on that yet) I'll definitely be buying another set, just to keep in the case with the tool so I've always got a bit on hand.

Bought these with thr Bosch bulldog and they plough through masonry. They're cheaper bits out there so that will do the job but these are worth the extra
