Chisel SDS-Max GEKO 40 x 350 mm model 40015

Chisel SDS-Max GEKO 40 x 350 mm model 40015 is a heavy-duty masonry chisel designed for use with rotary hammers that accept SDS-Max fittings. Constructed from solid steel, the tool features a 40 mm blade width and an overall length of 350 mm, providing the reach and cutting edge needed for chiseling, concrete removal and surface preparation on construction and renovation sites. The geometry of the blade balances penetration and material displacement to help maintain efficiency during prolonged use.

Advantages

The solid steel construction offers durability and resistance to deformation under high-impact loads. The 40 mm blade width provides a broad cutting surface for effective material breakout while the 350 mm length gives additional reach for deeper work without compromising control. Compatibility with SDS-Max rotary hammers ensures secure mounting and reliable power transmission during demanding demolition and chiseling tasks.

Suitable for

• Chiseling and shaping concrete and masonry
• Demolition of small to medium concrete sections
• Removing tiles, mortar and plaster layers
• Preparing surfaces for renovation or repair

Key specifications

• Blade width: 40 mm
• Overall length: 350 mm
• Shank type: SDS-Max compatible
• Material: solid steel construction
• Intended use: heavy-duty chiseling and demolition

How to use

Insert the SDS-Max shank into the rotary hammer chuck according to the tool manufacturer's instructions until it locks securely. Select the hammer or chisel mode on the rotary hammer if available. Position the chisel tip on the work surface at the desired angle and apply steady control of the tool; allow the machine's impact energy to drive the chisel rather than forcing it. For extended cuts or deep removal, work in incremental passes and reposition as needed to maintain control and prevent overheating of the tool.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection and gloves. Match the chisel with a rotary hammer of sufficient impact energy for the intended task and avoid side-loading the shank. Inspect the chisel regularly for wear or damage and replace it if the cutting edge becomes excessively worn or the shank shows deformation.
