Rotary Hammer Drill Bits Set & Chisels- SDS Plus 17PCS Concrete Masonry Hole Tool with Storage Case for Concrete, Stone, Brick

These bits are amazing! I ordered 5, thinking I would go through several of them while drilling rebar holes in solid bedrock and concrete. I'm still on the first bit after well over 100 4-6 inch holes. Would definitely recommend these bits.

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.

very good value and the selection is good,really only used one bit,but it did the job! recommend this set.

Good quality

I only needed one, but this was a better deal than getting a single bit at the hardware store. And now I have spares if one breaks or someone needs to borrow one. Went through rock without any issues and was quick. Also, came in a case, another bonus.

Great bits and chisels love the different sizes

Used one of the bits to expand three 1/2 inch holes in red brick to anchor a 2x4 piece of wood. The tops of the bit is showing wear. Surprised because I was just making 1/2 holes bigger (not making a new hole) and didn’t expect to see so much wear on the tips of the bits.

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.
