Nice item works great

These drill bits make the most daunting task a piece of cake. These bits melted through a .625 thick stucco wall. I was expecting to brake a sweat. With that said after repeated use. I did experience some performance degradation, but that is expected. In summary these are worth every penny and will get the toughest job done in a breeze. My one complaint is I wish these came in a sturdy hard plastic case. The flimsy platica that it comes in allows the user to roll up the bits and store them in a tool box or work bag, never the less they came in some sort of reusable storage.

We are hanging shelving in our garage's concrete block walls. The bits last for about 2o holes each before dulling out. Still...worth the money.

I bought these drill bits to install a new mailbox and an address plaque on the brick wall that's adjacent to my front door. These drill bits worked beautifully to make the holes in the masonry and bricks to securely mount/install my address plaque and mailbox. If you want quality drill bits at a reasonable price, then buy this set.

Perfect holes for grab rails in bath with shower. Perfect holes thru tile then wall. 3/8" bit made a perfect hole for the anchors - no chips in tile around hole! Very nice set of mason bits. I like that the smaller sizes come with 2 bits for extended use.

These aren't bad but I broke the tip on my first go through stone. This was probably the most difficult test for the bit and they would probably handle concrete just fine.

I bought these drill bits for a job that had a ton of concrete work. These bits withstood all my drilling needs. My coworkers used different bits and went through several different bits because they would become dull. I literally used the same bit for the job and it was going through the concrete like a hot knife through butter. Bought another pack, to have for future jobs; just in case these sell out.

I was a bit uneasy about buying these due to the low price, but was very pleased at how they performed. The drill bits went through concrete and concrete block with no problem. Highly recommend these.

Does the job
