Rotary hammer chisel attachment YATO YT-09901, 120 mm, set of 4, black

YATO YT-09901 rotary hammer chisel attachment set contains four hardened steel chisels, each 120 mm long, designed for use with compatible YATO rotary hammers. The chisels are finished in black and provide a straightforward replacement option for common chiselling and light demolition operations on masonry and concrete surfaces when paired with models that accept this style of attachment.

Advantages

The set offers four identical chisels that simplify tool preparation and reduce downtime during jobs that require multiple replacements. Hardened steel construction increases wear resistance for repeated use in masonry and concrete. The 120 mm length balances reach and control for both narrow access points and general surface work. The black finish helps identify the bits and may reduce visible staining from repeated contact with mortar and concrete.

Suitable for

• Chiselling mortar joints and removing loose mortar
• Light demolition of small concrete elements and tiles
• Shaping and trimming masonry blocks and bricks
• Site maintenance tasks where quick chisel changes are needed

Key specifications

• Quantity: set of 4 chisels
• Length: 120 mm per chisel
• Material: hardened steel
• Finish: black
• Compatibility: designed for use with compatible YATO rotary hammers that accept this attachment style

How to use

Ensure the rotary hammer is switched off and disconnected from the power source before fitting or removing chisels. Insert the chisel into the tool’s chuck or quick-change holder following the rotary hammer manufacturer’s instructions until it locks securely. Select an appropriate hammer and rotation mode for chiselling tasks, and position the chisel tip against the work surface at the correct angle. Apply steady pressure while allowing the tool’s impact action to drive the chisel; avoid forcing the bit to prevent premature wear or tool strain. After use, clean debris from the shank and store the chisels in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and gloves. Verify that the chisel type and length are suitable for the specific rotary hammer model and task. For prolonged work on reinforced concrete or heavy demolition, select purpose-built demolition tools rather than light chisels to avoid accelerated wear or damage.
