Chisel or moil point? How to choose a breaker tool type
A tool must first fit your breaker model; its type is chosen for the job. The difference between chisel, moil, blunt and pyramid tools.
Chisel (flat) tool
It has a flat edge and strikes along a line. It is used in soil, soft rock, asphalt and for splitting concrete, to break along a line or to open a trench. The edge is turned to suit the job.
Moil point
It focuses the blow on a single point and penetrates. It is the most common tool for general breaking in concrete and rock; if you are not sure which to choose, most jobs start with a moil point.
Blunt and pyramid tools
A blunt tool spreads the blow over a wide face; it breaks large blocks, hard and brittle rock and slag. A pyramid tool combines the penetration of a moil point with a tougher tip; it is preferred for hard rock and reinforced-concrete demolition.
Which tool for which job
A chisel for trenches, ditches and cutting asphalt; a moil point for general breaking in concrete and rock; a blunt tool for large blocks and hard rock; a pyramid tool for hard rock and reinforced concrete. Whatever the tool, keep it square, avoid blank firing and never pry with it.
When you choose a tool
Whatever the type, the diameter, length and key slot are set by your breaker model. Search your breaker’s make and model on the tool pages to see the tools that fit it, with their types.
