Finishing or trimming metal? Deburring aluminum or steel? The light, powerful and comfortable 525DM pencil style tools have speed ranges of 30,000 and 40,000 rpm, with collet capacities of 1/4″ or 6mm. The slim barrel styling provides easy access for hard-to-reach areas.
Optional collets are available for varied applications. The vibration level is 1,1 mm/s_ and noise level under 67 dBa. These features dramatically reduce operator fatigue and risk of injury.
The 525DM may be fitted to the shop’s hose assembly or our air supply assembly with fittings. The 525DM has a deadman’s handle for quick, easy shut-off.
