ABSTRACT:
An oscillating tool, particularly a cast cutter (40) having a support housing (46) with a cutting blade (70) interconnected to the housing (46) proximate one end thereof for oscillatory rotational movement about an axis (56) is disclosed. A torsion shaft (54) is fixedly interconnected at a first end (102) to the housing (46) so as to prevent rotational oscillation at the first end of the torsion shaft (54). The torsion shaft (54) further has a free second end (100) enabling oscillatory rotational movement of the second end (100) generally about the axis (56) of the cast cutter blade (70). A hollow tubular rotor support member (58) substantially more rigid than the torsion shaft (54) is attached to the torsion shaft (54) proximate the second free end (100) of the torsion shaft (54). The hollow tubular rotor support member (58) is concentrically positioned about the torsion shaft (54) and extends from proximate the second end (100) of the torsion shaft (54) along a major portion of the torsion shaft (54) toward the first end (102) of the torsion shaft (54). The cutting blade (70) is interconnected to the hollow tubular rotor support member (58) and torsion shaft (54) arrangement proximate the second end (100) of the torsion shaft (54) for oscillatory rotational movement therewith. A magnetically interactive rotor (60) is fixedly attached to the hollow tubular rotor support member (58) at a location axially removed from the cutting blade (70) for oscillatory rotational movement therewith. A magnetically interactive stator (66) axially adjacent but radially removed from the rotor (60) induces rotational oscillation of the rotor (60) and consequently the tubular member (58). Accordingly a rotational oscillatory movement of the cutting blade (70) is provided.
