Chisel Irwin 10501707 with Impact Protection, 20 mm blade

Irwin 10501707 with Impact Protection, 20 mm blade is a hand chisel designed for controlled wood cutting, shaping and detail removal. The tool combines a hardened steel blade and a reinforced head area to tolerate hammer strikes, allowing both manual chiselling and light impact use. Its 20 mm cutting width suits precise paring tasks and small-scale demolition where accurate removal of material is required.

Advantages

The hardened steel blade maintains a sharp edge for longer life and consistent cutting performance. An integrated impact protection system reduces stress on the handle and head junction during hammer strikes, increasing durability under impact conditions. The reinforced head area distributes force evenly to minimise chisel deformation and improve safety. The 20 mm width offers a balance between precision and material removal rate for common carpentry and detail work.

Suitable for

• Carpentry — paring joints, fitting tenons and trimming edges
• Detailed demolition — removing small sections of wood, plaster or glued joints
• General woodworking — shaping, trimming and finishing tasks
• On-site repair work where controlled impact is required

Key specifications

• Blade material: hardened steel for wear resistance and edge retention
• Cutting width: 20 mm for precise paring and trimming
• Head design: reinforced to withstand hammer strikes
• Intended use: manual chiselling with capability for light impact use

How to use

Secure the workpiece before chiselling and mark the area to be removed. Hold the chisel with a firm grip on the handle and position the bevel appropriately for the desired cut angle. For paring and shaving, apply controlled push strokes; for cutting or mortising, use a mallet or hammer strikes to advance the blade. Periodically check and maintain the blade edge by honing or sharpening to preserve cutting performance. Avoid using excessive lateral force to prevent blade damage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and work gloves. Match the chisel width to the task for efficient material removal and cleaner results. For repeated heavy striking, select a chisel rated specifically for heavy impact use or consider power-assisted removal methods to reduce wear on the tool.
