Concrete chisel GRAPHITE 57H558 flat 40 x 250 mm SDS-Plus

Flat concrete chisel GRAPHITE 57H558 with SDS-Plus shank, 40 mm working width and 250 mm overall length. Designed for use with SDS-Plus rotary hammers, this chisel is intended for chipping, cutting and removing concrete, masonry and plaster during demolition, refurbishment and surface preparation tasks. The tool features a hardened steel body and a ground cutting edge to provide consistent material removal on various construction substrates.

Advantages

The chisel's SDS-Plus shank ensures secure retention and fast bit changes in compatible rotary hammers. A 40 mm flat blade offers a balance between coverage and control, making it suitable for both targeted removal and wider scraping. Hardened steel construction increases wear resistance under repeated impact, while the ground edge maintains cutting efficiency across common materials such as concrete, brick and render.

Suitable for

• Removing plaster and render from walls
• Chiselling and cutting concrete and brick
• Surface preparation before repair or recoating
• Small- to medium-scale demolition and refurbishment tasks

Key specifications

• Shank type: SDS-Plus compatible
• Blade type: flat chisel
• Working width: 40 mm
• Total length: 250 mm
• Material: hardened steel

How to use

Insert the SDS-Plus shank into the hammer’s chuck until it locks, following the rotary hammer manufacturer's instructions. Select the hammering or hammer-only mode appropriate for chisel work. Position the flat blade against the work surface at a suitable angle and apply steady, controlled contact; avoid levering the tool to prevent shank or blade damage. Work in short passes to gradually remove material, and clear debris periodically to maintain visibility and effectiveness.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, hearing protection, gloves and dust mask. Match the SDS-Plus rotary hammer power and impact energy to the task and avoid using the chisel in rotary-only mode. For prolonged jobs, inspect the blade for wear and replace when the cutting edge becomes excessively rounded or damaged.
