Century Drill & Tool 87913 Flat Hammer Chisel

This flat hammer chisel is made from high carbon alloy steel with precision hardening that maximises steel strength into the core. It is designed for general chipping, edging and channeling tasks in construction or renovation work. The shank is manufactured to precise tolerances for a perfect fit in rotary hammer drills. Professional tradespeople and serious DIY users will find it suited to heavy duty applications.

Installation and common issues

The chisel fits directly into a compatible rotary hammer drill thanks to its precisely toleranced shank. Ensure the tool is switched off and unplugged before inserting or removing the accessory. A loose or worn chuck can cause the shank to slip, reducing impact transfer and increasing wear. Applying firm pressure in multiple spots around the workspace helps achieve the best results and prevents the chisel from binding.

Practical limits of the SDS interface

The shank design follows the SDS standard used by rotary hammer drills, which transmits both rotation and percussion forces. This interface limits the chisel to tools that accept SDS shanks; it will not fit standard drill chucks or other mounting systems. The hardened steel can be resharpened to extend service life, but the cutting width and overall length are fixed by the forged shape. Continuous heavy use may eventually require replacement when the tip geometry is worn beyond resharpening.
