Masonry chisel DeWalt DT6820-QZ, single 530 g chisel for stone and brick

DeWalt DT6820-QZ masonry chisel is a single 530 g chisel designed for chiselling, cutting and shaping stone, brick and other masonry materials. Manufactured by DeWalt, this masonry chisel is intended for manual or powered striking tools and provides a robust tool for demolition, joint cleaning and surface preparation work on concrete, brick and natural stone surfaces.

Advantages

The DeWalt masonry chisel offers a hardened working edge and a forged body to resist deformation during repeated striking. At approximately 530 g, the chisel provides a balance between manageable weight and sufficient mass for effective material removal. The tool's geometry is optimized for controlled chiselling and joint cleaning, enabling accurate stock removal and surface profiling while reducing the risk of chisel wander.

Suitable for

• Removing mortar and cleaning joints in brickwork
• Chiselling out damaged brick or stone for repair
• Shaping and trimming masonry for fitting and finishing
• Small to medium demolition tasks on masonry surfaces
• Surface preparation prior to rendering, pointing or bonding

Key specifications

• Tool type: masonry chisel for stone and brick
• Weight: approx. 530 g (single chisel)
• Material: forged steel with hardened cutting edge
• Application: manual striking or use with power striking tools
• Intended tasks: chiselling, joint cleaning, surface preparation, demolition

How to use

Position the chisel with the cutting edge against the work surface and use appropriate striking tools such as a hand hammer, bolster hammer or compatible powered striker. For joint cleaning or mortar removal, angle the chisel to engage the joint and apply controlled strikes to avoid damaging adjacent masonry. For material removal or shaping, take successive shallow cuts rather than deep single blows to maintain control and reduce the risk of material spalling. Inspect the chisel before use for signs of damage and ensure the striking face and shaft are compatible with the striking tool.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, gloves and hearing protection. For best results, maintain the chisel edge by dressing or re-sharpening as needed and store in a dry place to reduce corrosion. Select a chisel weight and profile suited to the specific masonry task to balance control and impact energy.
