Masonry chisel Dedra WXD8040, single-piece, for stone and brick

Flat SDS‑MAX Chisel Dedra Dłuto płaskie 80×18×400 mm is a heavy‑duty chisel intended for use with SDS‑MAX rotary hammers and demolition hammers. The tool features a wide, flat cutting edge and a long shank to reach into joints and work on surfaces during tile removal, mortar and concrete breaking, and general surface preparation. The steel construction is designed to withstand repeated impact forces typical for professional renovation and demolition tasks.

Advantages

The chisel offers a broad cutting profile that accelerates material removal across larger surface areas and helps maintain a consistent working line. Its SDS‑MAX fitting ensures quick, secure mounting and reliable energy transfer from the hammer to the tool. The length provides improved reach for deeper joints and harder‑to‑access spots, while the hardened steel construction increases durability under heavy impact conditions. The flat edge design minimizes chatter and gives control when levelling or scraping surfaces.

Suitable for

• Tile removal and adhesive scraping
• Mortar and grout removal from joints
• Concrete scaling and surface preparation
• Chiselling and levelling larger areas during renovation

Key specifications

• Chisel type: flat
• Shank system: SDS‑MAX compatible
• Working edge width: 80 mm
• Blade thickness: 18 mm
• Overall length: 400 mm
• Material: hardened steel designed for impact tools

How to use

Mount the chisel securely in the SDS‑MAX chuck of a compatible rotary hammer or demolition hammer according to the tool manufacturer’s instructions. Position the flat edge on the work surface at a suitable angle and apply controlled, progressive pressure while operating the hammer in impact mode. For tile or adhesive removal, begin at a seam or weakened section and work across the surface. For concrete or mortar removal, use steady passes and avoid forcing the tool beyond its intended angle to prevent premature wear. Inspect the chisel periodically for wear, deformation, or cracks and replace it if the cutting edge becomes excessively worn.

Usage recommendations

Use appropriate personal protective equipment including impact‑rated eye protection, hearing protection, gloves, and dust control measures. Select the flat 80 mm edge for broad scraping and levelling tasks; for precision or narrow joints use a narrower chisel. Keep the shank and chuck clean and lightly lubricated if recommended by the hammer manufacturer to ensure secure fit and efficient impact transfer.
