HammersRough Out
Overview
An air-powered hammer that drives a chisel at thousands of blows per minute. It turns a week of roughing out into an afternoon, and it turns a small mistake into a large one just as quickly. Noise, vibration and dust all scale up with the removal rate, which is why it sits at the far end of the workshop-safety spectrum.
Using it
- Stop at least 25 – 30 mm from your intended surface. The tool has no fine control.
- Let the tool cut at its own rate. Pressing harder stalls it and wears the piston.
- Work the mass, not the form. Everything within 30 mm of the surface is hand-tool work.
- Oil the tool every session, and check the chisel shank for wear — a worn shank will not hold.
Safety notes
- Hearing damage is the most common injury from pneumatic tools. 95 – 110 dB(A) requires hearing protection, always.
- Hand-arm vibration syndrome is cumulative and permanent. Limit continuous trigger time and take real breaks.
- A pneumatic chisel removes stone fast enough to sever a finger. Both hands on the tool, never on the work.
- Dust volume is far higher than hand work. Extraction and P100 filtration together.
