DEWALT DT6803-QZ SDS-Plus Flat Chisel 40 x 250 mm

The DEWALT DT6803-QZ SDS-Plus Flat Chisel 40 × 250 mm is a single-piece steel masonry chisel engineered for heavy-duty surface removal. Operating as a flat chisel, the attachment is built to take direct, high-impact force rather than functioning as a standard rotary bit. Its main use is fast chiselling and demolition-style chipping on a range of building structures. The flat profile concentrates striking energy along a defined edge, so operators can control break lines with accuracy. Builders and renovators often use this head shape to strip unwanted layers or to rough out wall openings.

An SDS-Plus shank allows secure fitment with compatible rotary hammers and dedicated impact tools. The grooved connection locks directly into the matching chuck, preventing slippage while transferring the hammer's energy to the work surface. Standard connections support quick, tool-free bit changes on site. Because the attachment works entirely by percussive action, it keeps up continuous striking force without any need for the chuck to rotate. Operators carrying out sustained demolition work benefit from this steady energy transfer and predictable handling.

• 40 mm cutting width provides a broad strike zone for clearing mortar joints and stripping surface materials.
• 250 mm overall length gives enough reach for recessed tasks while keeping the core rigid under load.
• Rated for structural masonry, and effective on concrete, natural stone, and brick or block walls.
• Designed solely for impact operation, bypassing rotary drilling so all applied force goes into percussive chipping.
• SDS-Plus compatibility ensures secure tool retention and direct power transfer in rotary hammer drills.
