Abstract
A hand tool apparatus uses a cutting tool with a first width and a tool axis to machine a hole in an object. The hole has a second width at least as large as the first width of the cutting tool. The apparatus includes a housing, a spindle unit in the housing for rotating the cutting tool and an orbital drive for rotating the spindle unit. An axial feed mechanism moves the orbital drive and the spindle unit jointly either toward or away from the object being machined.

A hand tool apparatus for using a cutting, tool with a first width and a tool axis to machine a hole in an object, the hole having a second width at least as large as the first width of the cutting tool, said apparatus comprising:
- a housing including a top and a bottom plate;
- a carrier axially moveable between said top and said bottom plate;
- a spindle unit having a principal axis including a spindle motor and a spindle shaft for driving the tool, said spindle unit extending through said carrier and secured thereto against axial movement while being rotational relative to said carrier about said principle axis;
- an orbital drive motor mounted on said carrier, and drivingly connected to said spindle unit for rotating said spindle unit about said principal axis relative to said carrier;
- and
- an axial feed mechanism configured for moving said carrier between said top and said bottom plate.
An axial feed mechanism for a hand tool, the hand tool having a principal axis, a housing including a top and a bottom plate, a spindle unit rotatable in the housing about the principal axis, and a motor configured for rotating the spindle unit about the principal axis, said axial feed mechanism comprising:
- a carrier moveable along the principal axis between the top and the bottom plate, said carrier secured to the spindle unit in an axial direction and the spindle unit rotatable in the carrier about the principal axis, and the motor secured to the carrier;
- and
- an axial adjustment cylinder secured to the housing, and including a cylinder rod extendable and retractable relative thereto, said cylinder rod secured to said carrier.
A hand tool apparatus for using a cutting tool to machine a hole in an object, said hand tool apparatus comprising:
- a housing;
- a spindle unit disposed in said housing and configured for rotating the cutting tool;
- an orbital drive disposed in said housing and configured for rotating said spindle unit;
- and
- an axial feed mechanism associated with said housing and configured for advancing and withdrawing said spindle unit and said orbital drive jointly within said housing relative to the object.
