SHALL 10-Piece SDS Plus Bits, 7 Rotary Hammer Drill Bits, Wide Flat Chisel, Gouge Chisel & Point Chisel, 4-Cutter Carbide Tips, for Concrete, Brick, Stone, Masonry, Roll Up Storage Pouch Included

I work in The HVAC field. I live day to day using a drill. At home And work I use this set constantly. These bits stand the test. As long as one practices high pressure slow speed on steel, and high pressure high speed on aluminum, the life expectancy is outstanding! I purchased this set 4 months ago and will repurchase when it’s time to replace them -Money well spent

I am an occasional DIYer and I don’t want to spend too much on expensive brands. This set covers all my needs. It breaks concrete and drills holes on it quickly. I don’t know how long it will last but I don’t see visible wear out after few uses.However, the first one I received has cracks on the “brand new” chisel and that is dangerous and that is not acceptable. I returned it and the replacement seems ok but I will always check before and after uses to ensure it is safe:

I used one bit on 22 holes 4 inches deep and the went through concrete and rebar like butter from the first hole to the last

very strong and useful

I can’t comment on the length these will last but so far have performed quite well with a huge assortment for basically the price of what 1 would have cost me local

Item works. I only used two item so far. Brought it for my occasional 30y old concrete holes. The tile remover works but I advise you to get a longer one. This is too short for lower angle. Can't beat the price

Bits fit perfectly with my Bosch hammer. Only complaint is that they are to short.

Have not tried them yet, but they look great !
