Where Is a Moil Point Tool Used?
Moil point tools are made for loosely bound or easily separable materials. Their slender, tapered profile allows pinpoint tip placement, so each impact drives the tool into the material without deflection, with less chatter and slippage.
- Primary demolition
- Primary breaking
- Trenching
- Scaling
- Recycling
According to the material table in our manual, it is recommended for non-reinforced concrete slabs, walls and foundations, and for lightly fractured or massive sedimentary rock (limestone, sandstone).
The hard rock version is made from a high-nickel alloy and goes through a special hardening process. It withstands extreme impact forces and abrasive rock, and is the preferred choice for heavy quarrying and mining.
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.
