Don't drill too fast.
Works well for Mortar Joints.

Drilling’s a breeze!
Not quite like cutting butter with a hot knife, but these bits really do get through my brick very quickly. Cheaper concrete/brick bits just don’t get it done or get dull quickly. Very pleased.

Masonry bit
I am a huge fan of Irwin's line of impact performance series power bits and drill bits. They are very well made, durable, and precise. These are no different...with a heavy, solid feel to them they are made to last and stay sharp after multiple uses. Much better than those cheap bits that come with the masonry screws. The 1/4" hex shank allows it it to be used in an impact which means you don't need to lug a drill and impact around the job site. Drill the hole with the impact, put you 5/16 nut setter in the impact or if you have the attachment slide it over this bit and tighten the screw.....fantastic

Bores into concrete with aggregate very well.
This drill performs really well cutting 4" deep holes in my septic tank that has a high ratio of small aggregate to concrete. I am using a Skil 1/2" hammer drill to drive it and it takes a couple of minutes per hole. I had planned to use the screw drive adapter that is compatible with this drill bit to drive the TAP screws into the concrete but, in my case, the screws require an impact driver to seat them.

Better concrete drill bits than the ones that come with tap-cons
I liked these drill bits because they were stronger than the ones that came with the tap-cons for installing hurricane shutters. These last about 4-5 windows and then are worn out.

a solid drill bit for landscaping timbers
While the screws I used didn't have to have a starter hole I like to be able to prevent pressure on the wood. This drill bit went all the way through the landscaping timber easily and worked for the entire job. 40 timbers 4 holes per timber. very pleased with the product.
