The Irwin SDS-MAX narrow chisel 25×280 mm (model 10502187) is a professional replacement chisel designed for SDS‑MAX rotary hammers and demolition hammers. With a 25 mm blade width and 280 mm overall length, this chisel provides a narrow profile for precise chiselling, grooving and light demolition tasks in concrete, masonry and similar building materials. The hardened steel tip and reinforced shank are engineered to withstand repeated impact while maintaining edge shape for accurate forming work.

Advantages

This Irwin SDS‑MAX chisel offers a combination of durability and precision. The narrow blade allows controlled material removal and accurate groove shaping, while the SDS‑MAX shank ensures secure, vibration-resistant retention in compatible rotary and demolition hammers. Heat-treated construction and a wear-resistant tip extend service life under frequent use, reducing downtime for blade changes.

Suitable for

• Chiselling narrow grooves and slots in concrete and masonry
• Removing small sections of material during renovation and repair
• Detail demolition where controlled removal is required
• Preparing channels for anchors, pipes or conduits

Key specifications

• Blade width: 25 mm

How to use

Fit the chisel into an SDS‑MAX compatible rotary hammer or demolition hammer according to the tool manufacturer's instructions, ensuring it locks securely. Position the narrow chisel on the work surface at the required angle and operate the hammer at appropriate power settings for the material. Apply steady advance pressure and allow the hammer's impact action to do the cutting; avoid forcing the tool to prevent premature wear. Retract and reposition as needed to create grooves or remove material accurately. After use, clean debris from the shank and inspect the tip for wear or deformation before storing.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, hearing protection and gloves. Match hammer power and impact settings to the task to optimize chisel life. Replace the chisel when the tip is significantly worn or deformed to maintain cutting precision and safe operation.
