A hand held machine for grinding and like operations, includes a housing, a motor mounted in the housing and which rotates an axle connected to a tool carrying mechanism, and a front bearing arrangement provided between the housing and the axle, including a front bearing, and a vibration insulator which is resilient to radial displacement of the axle. The vibration insulator includes at least one resilient element located between the housing and the front bearing. The machine further includes an adjustment mechanism interacting with the at least one resilient element for adjustment of the resilience of the resilient element. |
