Precise detail work – with a 3mm collet and 58,000 rpm free speed
High free speed combined with a small-diameter collet allows fine rotary tooling to operate at consistent peripheral speeds, aided by an air motor fitted with quality bearings for smoother rotation. The 3mm (1/8") collet accepts small grinding points for tight, accurate cuts.
Accurate shaping, deburring and polishing in confined areas, ideal for jewellery, model work or precision metal finishing.
Quieter, steadier running – thanks to shrouded exhaust and quality bearings
A shrouded exhaust redirects airflow and reduces direct noise emission while quality bearings lower internal friction and vibration, reflected in the provided noise and vibration readings. Noise power/pressure is specified as 82/71 dB(A) with vibration uncertainty listed as 1.
Lower perceived noise and reduced vibration make prolonged use more comfortable and less fatiguing on the hands.
Ready to use and maintain – with included accessories and in-line oiler
The kit includes ten grinding points, spanners, air tool oil, an in-line oiler, quick connector and chuck wrenches, enabling immediate setup and routine lubrication. The in-line oiler feeds oil into the air motor to help prevent wear during operation.
Start jobs straight away and keep the air motor lubricated for longer service life with minimal additional purchases.
