Chisel SDS-Plus DeWalt DT6802 20 mm diameter 250 mm length

DeWalt SDS-Plus chisel DT6802, 20 mm diameter and 250 mm length, is designed for use with SDS-Plus rotary hammers for chiselling, removal of tile adhesive, mortar and light demolition work. The 250 mm length gives extended reach in confined spaces or when working deeper into walls, while the 20 mm working profile concentrates impact force for efficient material removal. Constructed from hardened steel, the chisel is intended for professional and DIY users who require a durable bit with a long reach and consistent fit in SDS-Plus chucks.

Advantages

The chisel's hardened steel construction provides resistance to bending and wear during repeated impact use. A 20 mm wide profile balances material removal speed and control, and the 250 mm overall length increases accessibility without compromising transfer of impact energy. The SDS-Plus shank ensures secure, quick fitting and compatibility with a wide range of rotary hammers designed for SDS-Plus tooling.

Suitable for

• Chiselling concrete and masonry
• Removing tile adhesive and plaster
• Light demolition and renovation work
• Reaching deeper joints or cavities

Key specifications

• Shank type: SDS-Plus compatible
• Working diameter: 20 mm
• Overall length: 250 mm
• Material: hardened steel
• Intended use: chiselling, adhesive and mortar removal, light demolition

How to use

Insert the SDS-Plus shank into a compatible rotary hammer according to the tool manufacturer's instructions and secure it in the chuck. Use the chisel in hammer or hammer-drill mode appropriate for your rotary hammer, applying steady, controlled strokes and allowing the tool to deliver impact energy rather than forcing the bit. For tile adhesive or mortar removal, position the flat edge under the material and work along joints or surfaces to loosen and lift debris. For chiselling or light demolition, angle the chisel to concentrate force where material should separate, and work progressively to avoid overloading the bit.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves and hearing protection. Use the correct mode and speed on your rotary hammer and avoid excessive side loading. Inspect the chisel regularly for wear or deformation and replace it if the cutting edge becomes excessively rounded or the shank is damaged. Do not use the chisel in tools not designed for SDS-Plus bits.
