BoschHCK005 5-Piece Assorted Set SDS-Plus Bulldog Rotary Hammer Bits Ideal for Applications in Masonry, Brick, Block, Concrete

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.

Home Depot and Lowes couldn't touch this price

These SDS bits combined with the Bosch Bulldog rotary hammer drill makes light work of drilling into concrete to set anchors. And these bits go through cast pavers and cinder block like a hot knife in butter!

Aún no las eh calado lo suficiente pero hasta ahorita me han salido buenas y se ven de buena calidad

Used a lot with my Bosch rotohammer. The bits drill quickly and have held up to hard use.

Easy to use and priced well.

These work great and come with a small case to keep organized

Perfect to drill through concrete. My husband that is 49 years and it still works, but someone borrowed it and put a drill bit wrong- and jammed it. So I got him a new one.
