Chisel Irwin 10502185 pointed chisel 400 mm

Irwin 10502185 pointed chisel 400 mm is a hardened steel chisel designed for concentrated demolition and shaping of concrete and masonry. With a 400 mm overall length and a narrow, pointed tip, this chisel transfers impact energy to a small area for precise chip removal, splitting, and breaking. It is made for use with compatible pneumatic or electric hammers that accept the same shank profile and is intended for professional construction and renovation tasks that require focused chiselling performance.

Advantages

The pointed geometry concentrates force for efficient penetration into concrete, brick, and stone while reducing the risk of unintended fracturing around the impact zone. The long 400 mm length improves reach and leverage when working in deeper seams or recessed areas. Heat-treated steel construction provides wear resistance and consistent edge retention under repeated impact. Compatibility with hammer tools that accept the same shank type allows quick tool changes on site.

Suitable for

• Targeted demolition of concrete and masonry
• Removal of mortar and small sections of brick or block
• Creating starter holes and controlled splitting in stone
• Chiselling in recessed or hard-to-reach areas
• Use with pneumatic or electric hammers of matching shank size

Key specifications

• Overall length: 400 mm
• Tip type: pointed narrow tip for concentrated impact
• Material: hardened steel suitable for repeated impact
• Application: concrete, brick, block, and natural stone
• Tool compatibility: for hammers accepting the same shank profile

How to use

Securely fit the chisel into the hammer according to the hammer manufacturer’s instructions, ensuring the shank is fully engaged and locked. Position the pointed tip against the target area at the desired angle and apply controlled hammer blows, allowing the tool to do the work rather than forcing it. For best control, start with lighter impacts to establish a break line, then increase force as needed. Keep hands and body clear of falling material and maintain firm grip on the hammer during operation.

Usage recommendations

Wear appropriate personal protective equipment including safety glasses, hearing protection, gloves, and respiratory protection if dust is present. Inspect the chisel before use for signs of excessive wear, bending, or cracks; replace if damaged. Match the chisel shank to the hammer’s recommended size and avoid using the chisel with incompatible tools. When chiselling reinforced concrete, be aware of embedded reinforcement and adjust technique to avoid tool damage.
