Zusammenfassung:Drive to the cutter 5 of a hand-held router is made via a pin-in-slot connection 9,10 (Fig 2) (not shown) with a sleeve 8 held in the collet 6 of the router-motor 2. The pin-in-slot connection allows the cutter-shank 7 to slide axially within the sleeve 8, and so vary the depth of cut, in accordance with deflection of a pivoted finger-lever 20 via an arm 18 that acts on a thrust bearing 13, to extend the cutter 5 from the sleeve 8 against the action of a spring. The cutter shank 7 may be retained within a modified sleeve 8 solely magnetically to facilitate change of cutter.
