Masonry chisel DeWalt DT6824-QZ — flat steel blade, 360 mm length, 50 mm cutting edge

DeWalt masonry chisel DT6824-QZ is a hand tool designed for chipping, shaping and removing mortar, brick and stone. It features a flat hardened steel blade with a 50 mm cutting edge and a total length of 360 mm, providing reach and leverage for masonry and renovation tasks. Supplied as a single chisel, the tool can be used with hand strikes or with compatible powered hitters where the tool design allows.

Advantages

The chisel’s flat steel blade is hardened for wear resistance and consistent cutting performance across masonry materials. The 360 mm overall length gives additional reach for work in tight or recessed areas while maintaining control. A 50 mm cutting edge offers a balance between material removal rate and precision for tasks such as mortar joint removal or shaping bricks and blocks. The single-piece construction reduces the number of joints vulnerable to failure and simplifies handling on site.

Suitable for

• Removing mortar from joints during repointing and renovation
• Chipping and shaping bricks, blocks and stone
• Cleaning out old render, plaster or concrete splashes
• General masonry repair and small demolition tasks

Key specifications

• Blade type: flat steel blade, hardened
• Overall length: 360 mm

How to use

Position the flat cutting edge against the mortar, brick or stone surface to be removed and strike the chisel with an appropriate hammer or mallet. For controlled material removal, use short, measured strikes and work progressively along the joint or surface. When used with a compatible powered hitter, follow the tool manufacturer’s instructions and secure the chisel correctly before operation. Inspect the chisel blade for damage or excessive wear before each use and replace if the cutting edge is chipped or overly worn.

Usage recommendations

Use suitable personal protective equipment such as safety glasses, gloves and hearing protection. Keep bystanders away from the work area, and store the chisel in a dry location to prevent corrosion. Do not strike the chisel with hardened steel hammers unless specified by the striking tool manufacturer.
