DEWALT DT6802-QZ SDS-Plus Flat Chisel 250 mm x 20 mm

The DEWALT DT6802-QZ SDS-Plus Flat Chisel, 250 mm × 20 mm, is a single-piece power-tool accessory built for rotary hammers. Made from solid steel, it is designed to withstand repeated high-intensity impact. It is used to break up and shape masonry and concrete. Typical applications include general demolition, bulk material removal, and surface preparation. It is rated for continuous impact on masonry, solid stone, poured concrete, and standard brick or blockwork. The flat blade geometry concentrates striking force so material fractures along a predictable line, directing the energy into a straight path that clears debris without cutting too deep.

A slotted drive shank mounts the tool directly into compatible rotary hammer chucks. The base design holds the accessory firmly while allowing the internal sliding movement required for hammer action. This mechanical connection transfers the host machine's kinetic energy straight into the workpiece. Operators can change the accessory quickly on site without keys or separate adapters. Because the chisel works only by linear impact, the rotary-drill function on the hammer must be switched off before use. The extended length gives adequate hand clearance when clearing channels or working close to adjacent walls. As a dedicated impact tool, the bit has no cutting flutes and is not suitable for drilling or rotation-based work.

• 250 mm overall length provides access to recessed joints and deep wall cavities.
• 20 mm flat cutting edge supports directional chipping and even surface levelling.
• SDS-Plus shank compatibility enables secure, tool-free installation in matching heavy-duty rotary hammers.
• Heat-treated steel construction reduces wear and tip deformation under heavy concrete impact.
• Dedicated impact design is for hammer-only use, with rotation disabled.
