The Ruko Pneumatic grinder has a rubberised, non-slip handle, which absorbs vibration and protects the user from slipping off whilst working. The speed can be adjusted by a Governor on top of the handle. It has a tool adapter made of hardened steel. The exhaust air is directed backwards through the handle by means of a 360 degree rotational principle. The Ruko Pneumatic grinder features an integrated air filter, which protects the motor from dirt that could get into the inside with the compressed air.
