Abstract
A tool holder for multiple cutting tools is provided with a cam device to permit precise adjustment of the location of at least one of the tools (for example, an end squaring tool) relative to another tool (a bevel tool). The tool holder is particularly adapted for use with a portable lathe having a mandrel extending through the holder.
Claims4
In a rotary cutting tool holder including a tool support rotatable about an axis and having axially separated proximal and distal ends, at least one axial opening for receiving a cutting tool bit that extends from the distal end of the support when received in said opening, a releasable lock for securing a tool bit to the holder in the opening, and a rotatable cam element mounted on the tool support for adjustably axially positioning the tool on the tool support with the cam rotational axis oriented generally radially of the tool support, the improvement comprising, said cam having only a single peripheral edge feature extending laterally into the axial opening adjacent its proximal end to form an abutment that is substantially axially movable within the axial opening by rotation of the cam, and means for securing the cam against rotation.
