5 5/8 in. x 1 1/4 in. 16 Tips Concrete Repair Patch Prepare Sds Plus Bushing Tool, 1 1/4 Inch Square Head Concrete Roughness Coating Remove Bushing Bit for Rotary Hammer (Pack of 1)

I’m doing a small job at the house and I need to compact the ground. The area is 5” wide at the most and there are no tools that save a homeowners wrist from hammer swinging and impacts. I used this with a sacrificial 2x4 and it worked wonders.

Work great, good quality.

I can't believe how well this works. I used it to perfectly scarify a 16in x 7ft section following a vertical crack in my concrete block wall in maybe 30-45min total. The things the slowed me down were dying rotary hammer batteries, jackhammer overheating, and periodic cleanup. If I had a larger, corded rotary hammer, it would have taken maybe 10min + wire-brushing & cleanup.A similar sized section on another wall took me almost a week! I was attempting to minimize dust, so I tried chiseling by hand at first, then I got a needle scaler and paint scouring discs for a pneumatic sander. Those worked ok, but my air compressor was acting up. So, I bought the rotary hammer and used several flat or pointed bits to finish it off (and I thought THAT was a game changer). This concrete repair bit though, blows everything else out of the water.Pros:-Gentle enough for concrete block and doesn't break chunks away. (Chisel bits do if you aren't careful.)-Easy to control; just sweep it around and it will easily erase any paint, drylok, spalling, etc.-Inexpensive for how incredibly useful it is-Less mess! Forget about any kind of spinning sanding/grinding discs. I duck taped my wet/dry vacuum (with hepa filter and bag) hose to my rotary hammer and it kept all of the microparticles out of the air (as far as I could tell). The only stuff it didn't catch were the bigger pieces which fell straight to the floor.Cons:-Sweeping in a straight line will create grooves since the teeth make an even grid.-They might be able to avoid this minor problem by making the rows of teeth staggered, but thatcould also introduce other problems. It's not a big deal though, just use it diagonally periodically,sweep with circular motions, or try the rotating hammer function on your tool.-It bugged me a little that the head was too big to angle into the mortar joints, but that's my problem. I just have to buy their toothed chisel blade now.Additional info on my wall not the review:The vertical crack likely hasn't moved in many years. I just discovered it after tearing out a stud wall in my basement to install a better one + better insulation. The previous owners knew the crack was there because they had steel beams installed to the sides of it, and I found paint inside it. They decided to just wall it up and put fiberglass batting over it! Needless to say, the batting looked awful. I'm going to repair the crack with the usual materials, but I will also epoxy a 1ft wide carbon fiber strip over it from floor to ceiling. I will hopefully never know if the repair fails. I'm doing my very best, walling it up, and forgetting about it. Can't say the same for the last people.

This little bit eats concrete. Great for smaller projects. I had a few of the nubs break off after about 200 feet of bushing form lines. I would use the sds max bits for larger jobs.

Works perfect with a Dewalt DCH133B

Attached to an inexpensive harbor freight 5.5amp hammer/chisel drill it made short work of removing high spots on a concrete floor so snap lock flooring would lay evenly .. it was a small area where high points were lowered and remaining area roughened for the leveling compound … approx 2’ x 6’ …. Bit is still in good condition . Took less than 30 minutes to roughen and clean/ wet for leveling

It works great for light concrete removal, just remember it's not for heavy-duty demolition work.

Well my cousin had me buy these for him to keep in his toolbox at his job. He said this word great on light concrete stuff. As soon as he started putting pressure on it, it snapped. It was a couple months later after after I bought it so I couldn’t return it for him by your own risk.
