Metalworking chisel GRAPHITE 57H547 — weight 634 g, single piece

GRAPHITE 57H547 metalworking chisel is an SDS‑Max grooved point chisel designed for power chiselling in masonry and concrete. The tool measures 18 mm in diameter and 400 mm in length, with a total single-piece weight of 634 g. Constructed for use with compatible SDS‑Max rotary hammers, this chisel combines a grooved tip and self‑sharpening action to maintain cutting performance while reducing the need for manual resharpening. Supplied as one piece in a polybag with hanger and sticker, it is intended for construction, demolition and workshop tasks that require efficient material removal and controlled breaking.

Advantages

The grooved point reduces the risk of the tool seizing while the hammer drill rotates, improving stability during chiselling. Self‑sharpening action extends service life and keeps cutting performance consistent over prolonged use. The SDS‑Max shank ensures secure retention and compatibility with a wide range of heavy‑duty rotary hammers. A balanced length and 18 mm diameter provide effective force transfer for breaking, cutting and chasing wall furrows.

Suitable for

• Power chiselling and breaking of concrete, bricks and stone
• Cutting and removal of loose masonry and hollow blocks
• Creating furrows and chasing walls for wiring and pipes
• Demolition detail work and controlled material removal

How to use

Install the chisel in an SDS‑Max compatible rotary hammer according to the tool manufacturer’s instructions and ensure secure locking before operation. Position the grooved point on the work surface and apply controlled hammering while guiding the tool to achieve the desired cut or removal. For chasing, use steady, progressive passes rather than aggressive single strokes to control depth and avoid over‑penetration. Allow the rotary hammer to do the work; do not force the chisel beyond the tool’s designed impact capacity.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection and gloves. Match the chisel to a rotary hammer rated for SDS‑Max accessories and select impact energy and speed settings suitable for the material. For best performance, clear debris regularly from the work area and inspect the chisel tip periodically; replace the tool if excessive wear or deformation is observed.
