Where Is a Chisel Tool Used?
Chisel tools are versatile, general-purpose tools that combine cutting action with controlled fracturing in medium-hard and veined materials. The sharpened edge penetrates reinforced concrete and hard rock easily.
- Primary demolition
- Secondary demolition
- Trenching
- Recycling
- Scaling
- Primary breaking
- Boom mounted applications
According to the material table in our manual, it is recommended for reinforced concrete slabs, walls, columns and foundations, heavily fractured rock, asphalt and frozen ground.
The dust grooves guide dust and fine particles away from the breaking zone. Visibility and precision improve, tool wear and heat build-up drop, and the tool keeps its performance longer.
Correct Use: Three Rules
- Work perpendicular. Keep the breaker at a right angle to the surface and avoid side loads. Angled pushing wears the bushings and moves the piston off the tool axis.
- Do not pry. Rocking the tool like a lever before it is fully seated, or rotating the breaker while the tool is embedded, is the most common cause of tool breakage.
- Do not twist the chisel. A chisel tends to rotate along its path. This twisting wears the retaining pin slots and makes the tool break at the slot.
Breakage caused by ignoring these rules is not covered by the warranty. See our tool selection guide, the tool use section and the Tool User Manual and Warranty Terms.
