Where Is a Pyramid Tool Used?
Pyramid tools penetrate non-abrasive materials of varying strength quickly. The pointed geometry and cutting angle give high penetration rates with little effort in concrete and similar materials.
- Primary demolition
- Secondary demolition
- Trenching
- Recycling
- Tunneling
- Primary breaking
- Landscaping
According to the material table in our manual, it is recommended for massive (monolithic) sedimentary rock.
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 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.
