Your rotary hammer is hammering but not breaking — and the chisel is slipping, mushroomed, or just worn past the point of effective impact. A scaling chisel that doesn't stay sharp costs you time, burns out the hammer, and leaves you doing demo work with a tool that should be doing demo work. The 1-1/2-inch scaling chisel is the wide-face bit for rotary hammers — meant to break up large surface areas fast: concrete demo, mortar removal, floor prep, scaling old tile and adhesive. The flat business end distributes impact across the full width. SDS-Max shank fits standard rotary hammer chucks.
