    摘要: An abrasive sheet 1 for a sanding or polishing machine, comprising a body portion 3 and a tip portion 5 providing a working point 11, the tip portion 5 being defined by a weakened region 7 between the body portion 3 and the tip portion 5, wherein the tip portion 5 can be separated from the body portion 3, turned through an angle (FIG. 2) and re-positioned adjacent the body portion 3 to change the working point 11. As a result, an iron-shaped abrasive sheet, for example, can be provided with a plurality of working points 11. The sheet can, therefore, be used for longer periods before it is worn out.

    摘要: The invention provides a braking system for a powered oscillating hand tool which tool comprises (i) a housing; (ii) a drive unit (2) having an electric motor (4) and a drive shaft (8); (iii) a bearing (28) mounted on the drive shaft (8) and located radially eccentrically relative to the drive shaft (8), adapted to drive a second drive shaft (26); (iv) means (22) for mounting an oscillating head (24) on the second drive shaft (26) and (v) brake means (30) for providing braking between the oscillating head (24) and the housing (6). The brake means (30) comprises (i) a reaction surface (35, 46); (ii) a resilient support member (32, 40) formed from a resilient material which material, under compression, provides a resultant load on the contact surface and (iii) an abrasion resistant contact layer (34, 44) mounted on the support member (32, 40).
