Chisel bit Bosch EXPERT SDS max-8C flat chisel 25 x 400 mm 2608901697

The Bosch EXPERT SDS max-8C flat chisel 25 x 400 mm is a heavy-duty demolition accessory designed for use with SDS max rotary hammers. Constructed for professional chipping, concrete and masonry removal, and general material extraction, this flat chisel delivers consistent impact transmission and a stable fit in compatible SDS max tool holders. Its 25 mm blade width and 400 mm length provide a balance between reach and leverage for medium to large-scale removal tasks.

Advantages

This flat chisel features a robust forged design that resists deformation under high-impact loads and maintains edge geometry over extended use. The SDS max shank ensures secure locking and rapid bit changes, reducing downtime on job sites. Precision-ground cutting edge improves material penetration and control during chiselling operations, while the overall length provides better access to recessed areas and deeper joints.

Suitable for

• Demolition of concrete slabs, walls and floors
• Removing mortar and tile adhesive from masonry
• Chipping and shaping concrete and stone
• Creating channels or recesses for installations

Key specifications

• Shank type: SDS max compatible shank for rotary hammers
• Blade width: 25 mm
• Overall length: 400 mm
• Geometry: flat chisel profile for broad material removal
• Material properties: forged steel construction for impact resistance

How to use

Insert the SDS max shank into the rotary hammer’s chuck until it locks according to the tool manufacturer’s instructions. Select the hammer or chisel mode as required and position the flat chisel on the work surface at the desired angle. Apply steady, controlled pressure and allow the tool’s impact energy to do the cutting; avoid forcing the bit. For consistent results, use smooth overlapping passes and adjust positioning to maintain control and avoid unintended damage to surrounding material.

Recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and gloves. Use a suitable SDS max rotary hammer rated for demolition work and match impact energy to the task. Inspect the chisel regularly for signs of wear or damage and replace when the cutting edge or shank shows excessive deformation. When working in confined spaces or on reinforced concrete, proceed cautiously to avoid tool overload and ensure stable footing.
