Wall Chisel AWTools Korona 40x72 mm model AW40300

The AWTools Korona wall chisel 40x72 mm model AW40300 is a masonry chisel intended for removal of plaster, mortar and light demolition on interior and exterior walls. Designed to fit handheld and compatible powered demolition tools without the need for an adapter, this chisel provides a flat, durable cutting edge for chiselling, grooving and surface preparation during construction and renovation tasks.

Advantages

This wall chisel features a robust blade profile and hardened working edge to withstand repeated impact while maintaining shape and cutting performance. Its 40 mm width and 72 mm length balance reach and control for targeted material removal, reducing the need for multiple tool changes. Compatibility with both manual and power demolition tools simplifies workflow on site and supports efficient removal of loose plaster, mortar joints and thin render layers.

Suitable for

• Removing plaster and render from masonry walls
• Cutting or grooving mortar joints and thin overlays
• Light demolition and surface preparation before replastering or tiling
• Working with brick, blockwork, concrete and cement-based surfaces

Key specifications

• Blade width: 40 mm
• Blade length: 72 mm
• Intended use: masonry chiselling, plaster and mortar removal
• Compatibility: fits handheld and compatible powered demolition tools without adapter
• Working edge: hardened for impact resistance

How to use

Securely attach the chisel to a compatible demolition tool or hold it firmly if used by hand. Position the blade at the intended removal point and apply controlled strikes or power tool impact, working progressively along the surface to avoid excessive force. Use steady, overlapping passes to remove plaster or mortar in layers and to create grooves. Inspect the blade regularly for wear and maintain a safe distance from adjacent finished surfaces to prevent unintended damage.

Usage recommendations

For best results, use appropriate personal protective equipment such as safety glasses, gloves and hearing protection. Match the chisel width to the task — the 40 mm blade is suitable for targeted removal and narrow grooving. Replace the chisel when the working edge becomes excessively rounded or damaged to maintain efficiency and safety.
