4 Inch Pneumatic Angle Grinder (100 mm Air Grinder)
Key points
- 10000 RPM air power for fast cutting and grinding
- 4 inch discs are low cost and easy to source
- Compact body reaches tight corners and panels
- No electric motor - safe in damp environments
- 5 cfm air consumption fits most standard workshop compressors
- Cool-running pneumatic operation helps fabrication and marine-repair teams sustain repeated cutting and grinding work
- A sensible spare for yards where compressed air is already piped to every bench
- Tool rooms can keep a dedicated grinder for weld dressing so the cutting discs stay reserved for stock preparation
- Being air powered, it can be signed out of a tool crib with no battery pairing, so units are returned and re-issued without a charging queue
- Fabricators can dress a weld at the bench and swap to a cutting disc without changing tool or waiting on a battery

Product detail
Air-powered 4 inch angle grinder that cuts and grinds without the weight of an electric motor, running on a standard workshop compressor. The 100 mm disc spins at 10000 RPM for fast cutting of sheet metal, bolts and light stock, and smooth grinding on welds and surfaces. The compact body reaches into tight corners where corded grinders will not fit, and the air motor is safe to use in damp or dusty conditions with no electrical shock risk. Consumption of around 5 cfm at normal operating pressure keeps it compatible with most shop compressors. Suited to auto body work, metal fabrication, maintenance and marine repair, this grinder gives crews a light, cool-running option for extended cutting and finishing jobs at a factory-direct price. Rental counters and fleet workshops can issue the grinder to different operators without treating it as a fragile tool, while the low-cost 4 inch discs keep consumable spend predictable right across a season of jobs. Because running cost sits with the compressor rather than the tool, a buyer can total the quoted 5 cfm across a whole station and size the machine for better energy efficiency.
