10-Pack SDS Plus 3/16" x 6" Rotary Hammer Drill Bits, Carbide Tipped for Brick, Stone and Concrete

Tougher than Milwaukee bits I bought. 20 2-1/2" holes in, still on the first bit.

Just what I needed to pilot hole concrete screws. The HD pack was too short

These thing last!!! Drilling stone, concrete, etc they just last and last. Awesome bits!

pretty good quality

These are probably not the highest quality, but I'd rather buy a ten pack of decent bits than one or two expensive ones and one doesn't last as long as it should and I'm angry about it because I spent so much money. Some of these last 3x longer than others in the set. They do the job and they're cheap. Bought two packs so far and got through my whole (decent/full sized) basement framing: one bathroom, one bedroom, two closets, 75% of the footprint (some is just storage) and around my utilities. Would purchase again. ***Update: Just found the hammer switch on my new hammer drill which worked for the last few boards WAAAAY better. 🙄. I'm an idiot***

For the price these offer a good value if you're going to be drilling a lot of concrete holes. They held up well as long as you keep using water to cool them off between drilling.

Nice bits nice price.

These are considerably better than the $8 M-brand ones at home depot. The $8. often broke after one hole, these drilled 10 int he same wall twice as fast and not one broke. So I guess I only really know the 1st one was 10x better. I hope the other 9 are just as great.

Bits work great to drill in concrete for installing concrete screws

Son de buena calidad no le piden nada a unas de marca reconocida
