Chisel SDS-Max GEKO G40019 40 x 400 mm

Chisel SDS-Max GEKO G40019 40 x 400 mm is a long-reach SDS‑Max chisel designed for use with rotary hammers and demolition hammers that accept SDS‑Max tool holders. The tool features a hardened working tip and a durable shank appropriate for chiselling, breaking and removing masonry, concrete and tile. Its 400 mm length gives increased reach for deeper joints and recessed work while the 40 mm blade width balances cutting area with controlled material removal.

Advantages

The hardened tip and reinforced shank provide extended service life under repeated impact. Compatibility with SDS‑Max holders ensures secure seating and efficient energy transfer from the tool to the chisel for effective material removal. The 40 mm blade width and 400 mm length make the chisel suitable for both precision chiselling and heavier demolition tasks where longer reach is required. The simple, single-piece construction reduces the risk of component failure and simplifies tool handling.

Suitable for

• Chiselling and splitting concrete and reinforced concrete
• Removing masonry joints and embedded mortar
• Tiling removal and underlay clearance
• Demolition of small to medium-sized structures and finish removal
• Work in recessed or hard-to-reach areas requiring extended reach

Key specifications

• Type: SDS‑Max chisel
• Blade width: 40 mm
• Overall length: 400 mm
• Material treatment: hardened working tip
• Construction: single-piece steel design compatible with SDS‑Max holders

How to use

Insert the chisel into the SDS‑Max chuck of a compatible rotary hammer or demolition hammer according to the tool manufacturer's instructions and ensure it is locked securely before operation. Align the blade with the work surface and apply steady, controlled pressure while operating the hammer at the recommended mode for chiselling or demolition. For best results, start with light passes to define the cut or break line, then increase force as needed. Maintain steady positioning to avoid slipping and to direct impact energy into the workpiece.

Usage recommendations

Use appropriate personal protective equipment including safety goggles, ear protection and gloves. Select the correct hammer power and impact mode for the material and task. Regularly inspect the chisel tip for wear or deformation and replace if the hardened edge is compromised. When working near reinforcement or utilities, verify the presence of rebar or services before chiselling. Store the chisel in a dry place to prevent surface corrosion.
