Chisel SDS‑Max GEKO G40023, 40 x 600 mm

The GEKO Chisel SDS‑Max G40023 is a heavy‑duty masonry chisel designed for use with SDS‑Max rotary hammers and demolition breakers. With a 40 mm blade width and a total length of 600 mm, this chisel is intended for controlled removal of concrete, brickwork and plaster in construction and renovation environments. The shank is manufactured to fit SDS‑Max toolholders, ensuring secure retention during impact work and compatibility with a wide range of professional power hammers.

Advantages

The chisel’s hardened steel blade provides resistance to wear and deformation under repeated impact. Its 40 mm cutting width balances material removal rate with precise control, making it suitable for both broad scraping and targeted chipping. The standardized SDS‑Max shank ensures reliable engagement with compatible rotary hammers and breakers, reducing slippage and improving energy transfer. The overall length of 600 mm offers extended reach for working on slabs, walls and ceilings while keeping handling comfortable for the operator.

How to use

Fit the chisel into the SDS‑Max toolholder following the rotary hammer manufacturer’s instructions, ensuring the locking mechanism engages fully. Position the blade against the work surface at the desired angle and apply controlled impacts with the rotary hammer or breaker. Use progressive passes to remove material, avoiding excessive lateral force that could bend the blade. Allow the tool to perform the work and maintain a steady, supported stance to control recoil and maintain accuracy.

Usage recommendations

Use personal protective equipment including eye protection, hearing protection and gloves when operating rotary hammers. Inspect the chisel before use for cracks or significant wear and replace it if damaged. Match the chisel width and shape to the task to optimise efficiency and reduce tool stress.
