Chisel Topex 300 mm flat 27 x 19 mm for concrete

Topex 300 mm flat chisel with a 27 x 19 mm blade is designed for use with demolition hammers and rotary hammers on concrete, mortar and masonry. The flat cross-section delivers a straight cutting face for surface removal, joint opening and controlled chiselling. Its 300 mm overall length provides reach and leverage for medium-duty demolition and repair tasks while the 27 x 19 mm flat blade balances penetration and material displacement.

Advantages

The chisel’s flat geometry creates a wide, even strike area that helps remove plaster, thin screed layers and damaged concrete without excessive gouging. Hardened working end and a consistent blade profile maintain edge geometry through repeated impacts, reducing deformation and ensuring predictable performance. The 300 mm shank length improves operator control and access into narrow joints or recessed areas. The tool is compatible with common SDS-plus and hex shank adapters when used with appropriate hammer models, allowing flexible application across demolition hammers and heavy-duty rotary hammers.

Suitable for

• Removing plaster, render and thin concrete screeds
• Chiselling out mortar joints and pointing removal
• Shaping and trimming concrete edges and surfaces
• Preparing surfaces for repair and patching

Key specifications

• Overall length: 300 mm
• Blade cross-section: flat 27 x 19 mm
• Blade type: flat cutting face for surface chiselling
• Material treatment: hardened working end for impact resistance

How to use

Secure the chisel into the compatible hammer chuck or adapter according to the tool manufacturer’s instructions. Position the flat blade against the work surface at a shallow to moderate angle to achieve controlled material removal; adjust hammer power and striking frequency to match material hardness. Use steady, guided passes along the area to be removed rather than concentrated blows in a single spot to avoid over-chiselling. Wear appropriate personal protective equipment, including eye protection, hearing protection and gloves, and ensure the work area is clear of bystanders.

Usage recommendations

For best results, match hammer impact energy to the task: lower energy settings for thin plaster and screed removal, higher impact for thicker concrete sections. Regularly inspect the blade for wear and regrind or replace if the cutting face becomes rounded or chipped to maintain efficient chiselling and safe operation.
