Well worth the price

Great 17-piece SDS Plus set. Bits and chisels are sharp, durable, and work perfectly on concrete and masonry. Very well organized and high quality. Highly recommend!

I picked up this rotary hammer drill bit set when working on some heavy-duty concrete projects around my home, including drilling through high-strength concrete for deck ties and anchor screws. After struggling (and overheating) with a standard corded drill (laughable, I know), switching to a rotary hammer with these bits was a game-changer. The 1/2" and 5/8" bits drilled through concrete like butter—smooth, fast, and precise. While I testament to the rotary hammer, the point is to acknowledge these bits repeatedly stood up to high strength concrete! The set also includes chisels, which I’ve used on the hammer-only setting, and they’ve performed just as well. The bit lengths were perfect for reaching through outer boards (e.g., ledger board) and getting deep into concrete. Similarly, they allowed for adequate retrofit placement of rebar and concrete footers when I needed to set rebar for a retaining wall. I’m not a contractor, just a serious DIYer, and this set has delivered exactly what I needed—strength, durability, and versatility. The included carrying case is a nice touch, keeping everything organized and ready to go. For the price, this is an excellent value. I’d absolutely buy from this brand again.

with this many bits i figured I'd be fine to pre drill drive some srews, no such luck! smalled bit is 3/16 but only 4 inches long, will not work.

Most of the SDS drill bits in the kit are crooked / not straight, some more than others (1/32 to 1/16 off center on each side). Out of the 12 bits, I'd say 2-3 are "straight" (less than 1/32 "wobble") They're hammer drill bits, so they'll still make the hole, but the 1/4 bit might end up making a 5/8 hole. Some were more "misaligned" than others, with the effect obviously compounded on longer bits. If you're making holes for anchors in concrete or bricks, make a dummy test first. You might have to go a bit size smaller to avoid over boring the hole of you anchor with a "wobbling" bit, and thus weakening it's hold. I will not return the kit since this was kind of expected at that price and not worth the efforts. Hey... it's a <50$ kit for 17 pieces. Good SDS go for 10-15$ PER BIT in the lower sizes So if precision drilling is what you're looking for, don't buy this.
