Chisel SDS‑Max flat narrow 25×280 mm Smart 12-013

The Smart Chisel SDS‑Max flat narrow 25×280 mm is a professional‑grade flat chisel designed for use with SDS‑Max rotary hammers and demolition hammers. With a 25 mm cutting width and 280 mm overall length, this chisel offers a slim profile for precise chiselling, grooving and controlled material removal in concrete, masonry and natural stone. The tool steel tip and reinforced shank are made to withstand repeated impact and deliver consistent performance in renovation and construction tasks that require concentrated striking force.

Advantages

This SDS‑Max flat narrow chisel provides a precise working edge for focused material extraction and clean groove formation. Its narrow geometry reduces collateral damage to surrounding surfaces and improves access in confined areas. The SDS‑Max connection ensures secure retention in compatible hammers, and the robust construction enhances durability under high‑impact use. The 280 mm length balances reach and control, allowing effective work on deeper joints without sacrificing operator handling.

Suitable for

• Chiselling grooves and channels in concrete and masonry
• Removing tiles, mortar and plaster in renovation projects
• Detail demolition work where a narrow cutting width is required
• Accessing tight spaces for targeted material removal

Key specifications

• Chisel type: flat narrow
• Shank system: SDS‑Max compatible
• Cutting width: 25 mm
• Total length: 280 mm
• Material: hardened tool steel tip with reinforced shank

How to use

Insert the chisel into the SDS‑Max chuck of a compatible rotary hammer or demolition hammer according to the tool manufacturer’s instructions, ensuring it locks securely. Position the chisel tip against the work surface at the desired angle and apply steady guided pressure while operating the hammer. Use short controlled blows for precision chiselling or longer strikes for faster material removal. Periodically inspect the chisel for wear and replace when the cutting edge becomes excessively rounded or damaged.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and gloves. Match the hammer’s impact energy and speed settings to the material and task; lower impact or slower speed improves control in precise work, while higher settings accelerate removal in heavy demolition. Keep the chisel clean and free of debris for reliable seating in the tool holder and store in a dry place to prevent corrosion.
