SDS Plus 1/2 Inch x 18 Inch Masonry Drill Bit for Rotary Hammers (Industrial Grade Carbide Tipped) Extra Long Perfect for Concrete, Cement, Brick, Stone, and More!

They work well in 'softer' materials, flower pots and such, and they are quite adequate for drilling in tile. In the softer work, I used them for drilling decorative flower pots, they ran good and seemed to last. In bathroom wall tile, I was able to get a dozen or so holes before noticeable dulling. One caveat, if you hit a screw or nail, the bit will chip and be marginal.Remember, this type of bit is a consumable item. These bits are a good value compared to some others I have used, they aren't heavy duty SDS bits and the price reflects that.I would recommend to a friend for light work and would buy again.

fast delivery, punch 5 holes in cement and work flawlessly.

What I liked: quality of the product was very good for the price, much better than I expected.What I disliked: the bits did not arrive on the stated date and I had to buy some bits locally for the first day of the project.

Well the choice was overwhelming. I never heard about this brand and wasn't sure. However, the price was right and delivery was prompt. I needed to replace my chewed up bit that gave in, midpoint in a minor project.The bits look good and feels right (weight, length, quality). The only problem is the packaging.The box is the cheapest one you could find. Once you get it open all the bits fly out of their respective slots. I will toss the original box and keep the bits in my bit's pocket from Milwaukee. So, no problem there.The bit went trough the brick that "ate" my old bit, like it was soft wax. Yes, really. I needed a 3/8 hole about 2 inch deep. Literally in seconds. Highly recommend.Oh, one detail - didn't use hummer mode on those. The ends look like they aren't designed for that.

MUY BUEN PRECIO Y CALIDAD.

I used the 1/4" bit to open a 3" hole in my basement slab for a radon mitigation system. I drilled out a bunch of holes in the slab until I got the hole cut out. The first bit broke drilling the hole. I used a second bit to loosen up the gravel pad underneath to dig out my suction pit. It's still in good shape. Overall it's a decent set. At the end of the day bits are a consumable and expensive or cheap bits will break on the job. These will work fine if you don't need the most clean or fast holes. I'd recommend using them.

I've been using hammer drills and bits for over 30 years and these are the worst I've ever used. They break. Very easily or lose the tip.. in the 1st use. I'll never buy them again

I used the two 10mm bits with a cordless Ryobi hammer drill. I was drilling concrete possibly 40-50yrs old. So granted that may be pretty hard concrete. I was able to drill two holes 2.5" deep each (so about 5" of drilling depth before the bits were dull. At first I was pleased as they did pretty well at first. I stopped every 1/2" of depth to clear debris with an air compressor. And I also switched bits every 1/2" to prevent overheating. I just re-read the review, and it didn't mention liquid cooling, but I did see that recommended for some similar bits from Joeric and Joeric also recommended not using a hammer drill, but just slow speed. I'll see how the Joeric bits do on Monday to finish the last few holes as I was unable to finish the job with only the two 10mm Owl bits.

Excellent and better than hom dpo

In the beginning I didn't have too much faith in it and I was thinking about returning my drive drill if this didn't work but for my surprise it worked pretty good and smooth. I bought a cheap one before in Dollarama but it was just useless. I can now keep both, the drill and this bits.They worked, trust me.

What a great set of Masonary bits. Best I have ever used!!!! Would highly recommend.

I got what I needed pretty quick

Très bonne mèche, essayé sur de la céramique
