AV Steel 5-Piece SDS Plus Rotary Hammer Drill Bits, Masonry Drill Bits, Carbide Tipped SDS Drill Bit Set for Drilling, SDS Plus Drill Bit Set for Brick, Masonry, Block, Concrete with Storage Case

Good quality for a tough job. Variety of sizes, easy to use.

This set was just what I needed. No problems. Thanks!

So far holding good edge, drills well

I say heavy as a good thing. I have not had cause to use these yet, but they appear to be pretty nice quality. This is a set that I want to have around when the need arises because I've needed some in the past and not had the right size. They are a good length and seem to be good quality as well.

The “AV Steel, 5-Piece SDS Plus Rotary Hammer Drill Bits, Masonry Drill Bits, Carbide Tipped SDS Drill Bit Set for Drilling, SDS Plus Drill Bit Set for Brick, Masonry, Block, Concrete with Storage Case” has carbide tips for longer lasting performance. It fits a rotary hammer drill and is for drilling masonry. I like this set because it includes all the most used sizes. I would not go so far as to call them superior drill bits, but for masonry, they will do the job.

Works great

Coming with a ⅜” SDS shaft, there are five masonry hammer drill bits in the kit. Four of them, the ½”, ⅜”, ⁵⁄₁₆”, and ¼” are 6” long, while the fifth bit, another ¼”, is 4” long. All five hammer drill bits come in a plastic case that keeps the bits separate so they don’t bang against each other. I live in a Florida concrete block house. Anything I want to attach to the house, like the garden hose holder I recently attached to a side wall near my outside faucet, needs anchors or concrete screws. That type of attachment hardware requires a hole drilled into, or through, the outer side of the concrete block. I used to painstakingly do so using a regular power drill with a masonry bit. It took forever to drill through with bits overheating and dulling. Coming across a hammer drill on sale recently, I decided to give it. I’m never going back to a hand drill. One negative I did experience with the hammer drill was that the old-style masonry drill bit shafts get chewed up by the hammer drill. The SDS shafts on these AV Steel bits solve that problem. They have plenty of surface area on their shafts for the hammer drill’s chuck to tighten against. When pushed fully into the chuck and tightened, there is no movement along the shaft from either the hammer drill’s high twisting torque or longitudinal hammering. The five masonry bit sizes received are the ones I use most. I only wish I’d been more patient in waiting for this masonry bit kit to come in before the garden hose holder mounting project.

While I have not tried all of the bits here, I needed to try out the 1/4" this weekend just going through a cinder block. I have a very low end hammer drill from the cheap tool store that every DIYer goes to. Usually I have a nice hard time getting through block, but with these bits, even my cheap little drill did the job easily. I was really happy with the performance. To see if it was a fluke, I did drill another hole, and got the same surprising result. It's amazing what happens when you have the right tool!!! Beyond performance info like the case they come in as well. All around a nice set to have access to!
