Where Is a Blunt Tool Used?
Blunt tools are designed to channel the full impact energy of the breaker straight into the toughest materials. They are built for maximum energy transfer and durability.
- Primary demolition
- Secondary demolition
- Secondary breaking
- Boom mounted applications
- Tunneling
According to the material table in our manual, it is recommended for large block breaking, crystalline rock such as granite and gabbro, and recycling of demolition debris.
The standard tool is made for general demolition, construction and quarry work. In very hard and abrasive rock the hard rock version lasts 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 blank fire. If the breaker strikes without the tool touching the surface, all the energy goes into the retaining pins and the tool's pin slots; pins break and slots are destroyed.
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.
