3/4x12 SDS-Plus Rotary Hammer Drill Bit, Carbide Tip 4-Cutter for Brick,Stone & Concrete, Packed of 2pcs.

These worked really well for drilling concrete base anchors. I’d recommend.

Bought these along with a new hammer drill, Punched 50 holes in 8" thick, 3000 psi concrete, cured for two months, and never dulled it. I've had brand name drills dull after just a few, so I'm impressed for the money.

Lasted very well for production work in concrete! Great value!

I'm impressed! This pair of 3/4x12" Hammer Drill Bits arrived quickly and are much better quality than the bits available at the Orange or Blue box stores, and at a fraction of their price. I appreciate the engineering of these Cross-X carbide tips with their double-helix shaft ... just so obviously better than the single Tee points and single helix you see on other bits ... even (so-called) "premium" bits. I only need to drill a single hole in my house slab, but I ordered the pair because buying these costs less than renting a hammetr drill and a single bit for four hours.

Pretty dang good bit. I was impressed for the price. I recommend.

Works as described

Worked very well, Quality was good, made quick work of 3/4" holes.
