PERFECT BITS FOR CONCRETE FITS RYOBI TOO

I initially bought the Bosch 7 pack and on the first day of a basement project, one bit broke into two, and another twisted in half

This product on the other hand is top quality. 4 inch length is also the perfect balance between length and rigidity - it's very unlikely you'll need to go much deeper than 3-3.5 inches.

I'm probably going to buy another set just as a backup.

Good for the price, but limited lifespan

I needed 28 holes drilled to a depth of 3" into a concrete block wall using a hammer drill. A single drill bit got through half the job before needing to be replaced. I'm not complaining, all masonry drill bits wear out, especially those under 1/2". Just use my experience to plan for your job.

At one time I used a regular drill bit to go through brick. Took it nice and slow and managed to make it through. Well, I figured cinder block would do the same. Wrong! Bought this to help out and BOY did it make a difference. It walked on me at first so my holes didn't light up perfectly but it was good enough to mount the key pad for my property gate.

This thing definitely did the job. Did NOT use a hammer drill and still was able to get through the cinder block very easily. Only used a couple of times and hasn't broken. Nice for price

The tip of this bit chipped on its first use drilling a 3/4" hole in concrete. I was still able to get the hole drilled but I was disappointed that it chipped so quickly.

Seems good for what I use it for

Bought this to put drainage holes in some planters. Worked well and didn't break the pots, so yay! Can't speak to how it would work for anything harder than that, but seems sturdy enough.
