BOSCHHCST006 6 pc. SDS-Plus® Bulldog™ Rotary Hammer Bit Set

Reliable Bosch Quality for Masonry WorkThis Bosch 6-piece SDS-Plus masonry set really hit the sweet spot for me. The chisels and carbide bits feel solid, well-balanced, and clearly built for heavy-duty use. I tried them on a block wall and some old concrete, and they cut in smoothly without wandering or dulling after a short session. The SDS-Plus shank fit snugly in my hammer drill with no slipping, which is always a relief when working on harder materials.I like that Bosch included both chisels and drill bits in one set—it covers the typical jobs I’d run into, from breaking up smaller sections of masonry to drilling holes for anchors. The carbide tips bite quickly and eject dust efficiently, and the chisels have a clean grind that holds up under pressure. The storage case is sturdy enough to keep everything organized, though it’s a little bulkier than it needs to be.The only minor consideration is that this set is really meant for hammer drills with SDS-Plus compatibility—so it’s not going to fit in a standard chuck drill. But if you’ve already got the right tool, this makes for an excellent go-to kit.Bottom line: A tough, versatile Bosch set that covers the essentials for masonry drilling and chiseling, offering great durability and performance in one package.

Got these to pair with my DeWalt rotary hammer, they're pretty sturdy.

It good quality and what I expect from Bosch.

Work great, don't dull easy. My only complaint is one came misformed making me have to hammer it into the sds and hammer it back out each time.

Great value for home use very happy.

Great product. It worked perfectly with my Makita hammer drill. Got the job done very quickly.Seller took a couple of days processing the sale but, once that was completed, the shipping was very fast and only took a couple of days.

I have been a firm believer in Bosch tools for some time. After selling my 18 volt converted to a 20 volt SDS Drill a while back, I came across the need to own another and a good set of SDS bits, as a project to add 30 plus shelf standards attached to concrete basement walls came up. After looking at the Bosch corded - which I found hard to beat from past use, I instead went with another cordless SDS, and added the Bosch SDS drill set. My first thoughts was that these wouldn't keep up with what I was needing to do. But once I started drilling any concern was resolved, the 3/16" bit was a beast and cut flawlessly. Coupled with the 60 volt Flexvolt SDS, it drilled flawlessly for over an hour, a total of 115 holes drilled. This were 3/16" and posed no problem for the Bosch bits. I haven't tried a 1/2" or 3/4" hole, that day is yet to come, but from what I needed, this drill bit set knocked it out of the park.

I use this professionally and find the bits to be good quality and last thousands of holes. I use the bits primarily and for setting anchors.
