PCT No. PCT/SE86/00068 Sec. 371 Date Sep. 22, 1986 Sec. 102(e) Date Sep. 22, 1986 PCT Filed Feb. 18, 1986 PCT Pub. No. WO86/04855 PCT Pub. Date Aug. 28, 1986.The invention relates to a displaceable protective cover for handtools using rotary, disc-shaped tools. The protective cover comprises two halves (7,8) which completely enclose the tool (3) when in their rest position. The cover-halves (7,8) can be rotated to an open position against the action of a spring force, and are connected to a latching mechanism (11,12), arranged to lock the cover-halves against further rotation when either of the cover-halves (7,8) is subjected to an impact force.
