SDS Plus Shank Four-Tooth Chisel, 7-17/20 Inch Long Round Shank Alloy Steel Hammer Drill Chisel, Four-Prong Flat Chisel, Ideal for Tile Concrete Brick Stone Masonry

This Rotohammer drill chisel filled a need for me, and it worked out great. Rather than a smooth chisel tip, this one has teeth. So, the cutting edge also scarfs the surface I am chiseling. This helps to make a better bonding surface for new materials, tiles, stone, etc.. This is super handy since I can remove old material and also get better bonding all in one run through. Anything that saves time really helps and this feature makes it a handy tool for me. The chisel is built well, and the carbide tipped teeth are holding up very well. I always prefer carbide for strength and longevity. The SDS-Plus shaft fits my hammer drill perfectly. Overall, this tool does a good job, and I am happy that I have it.

Some specialty tools for SDS hammer drills don't impress me much, but this is a serious solution to hard problems. It's long enough to reach into tight spaces, and it seems tough enough to put a serious hurt on the concrete, concrete block, brick or mortar objects you want to remove or modify. While its compact size will not let it compete with a jackhammer or SDS Max for sheer destructiveness, it promises a good balance between control and demolition for jobs that demand finesse.

Until now, I was only aware of straight edge or pointed tip SDS Plus chisels. This is better suited to chipping away at an angle stone, concrete or cement. The teeth give some additional "grip" or abrasion. I don't think this is best for trying to sheer off a piece (i.e. cut a piece off), but for chipping away protrusions or using on something that the straight edges don't work on, this is much better. It showed little wear other than some abrasions and that's likely due to the teeth being carbide. I'm happy I discovered this, I didn't know this "style" existed.

Multiple carbide cutter for 4 fracture points in the demolition material, strong steel shank and head, aggressive cutting. Will cut/fracture/remove concrete, masonry, tile, brick and stone. Had no issues in my rotary hammer, did not show any wear after an hour of use.
