BOSCH HCST006 SDS-Plus Bulldog Rotary Hammer Bits | Four carbide bits, flat chisel and point chisel, optimized brazing, heavy-load tips and Brute Tough storage case

Reliable Bosch Quality for Masonry Work This 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.

You can expect the usual Bosch high quality. The case has some nice, not immediately obvious, convenience features. Bits are holding up well after some light to medium use.

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.

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.

These bits are pretty amazing. I used both chisel and largest spiral with a hammer drill to make holes in a boulder in my backyard so I can insert feather wedges into them. The drill is entry level and isn't as powerful so it is hard to rate the total efficiency of these, but with patience, they definitely do the job and do it well. After about an hour of drilling, these still show no signs of wear and tear and haven't needed to be sharpened yet. I also used the spiral bit to drill a few small holes in a stump to pour some stump out into. Using the same hammer drill with drill function, these cut through it like butter. I definitely recommend these bits to accompany a hammer drill. They are durable, come in a nice case, and are very affordable. A side note, I have only used them for a few projects around the house and don't intend on using them daily. I cannot comment on everyday professional use.

Es un producto excelente, si quieres rendir en tu trabajo, o quieres hacerlo como todo un profesional lo necesitas!!!

I couldn't see anywhere in the description the sizes or contents of the set. Here are the contents: All drills have a 4" flute on a 6" shaft 1ea 5/32" 1ea 3/16" 1ea 1/4" 1ea 3/8" 6" Flat Chisel 6" point Chisel As another review stated, these are "short for most field work". However, for fine work the shorts give you good control. Plenty good for making holes for anchors and electrical boxes. Also, the bits are straight and cut an accurate hole. It could be the tool the other reviewer was using was not a true SDS Plus. I've heard some tools like the harbor freight stuff has bit size issues. This is an SDS plus sized bit set. The tips are of good quality, cut well, last better than anything else in it's price range and have a wear marker. Great starter set, great value.

This is a high quality bit set labeled for "standard concrete" meaning it has a PSI range of about between 2,500 and 5,000. A psi of 2,500 psi is sufficient for footings and walls, while 4,000 to 5,000 psi is considered good for pavements. Concrete used outside should range from 3,500 to 4,500 psi. With this in mind, this set is fantastic for most DIY projects not chopping up industrial strength concrete. I use it with a Ryobi P222 18V Rotary hammer and it works great. No chips on the bits and 0 lag on the tool. It can also be used to break tile, sheetrock, durock and more. The bit ends are SDS plus and work with all drills that comply with the standard. Once inserted, the bits are securely held and can only be removed by pushing the chuck in and pulling out at the same time. Great little starter set.
