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.
Claims14
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 to be machined by the cutting tool having a second width which is larger than the first width of the cutting tool, said apparatus comprising:
- a housing;
- a carrier non-rotatably mounted to and axially moveable relative to said housing;
- a spindle unit having a principal axis, said spindle unit including a spindle motor and a spindle shaft for rotating the cutting tool about said tool axis, which tool axis is offset from the principle axis, said spindle unit extending through said carrier and secured thereto against axial movement while being rotational relative to said carrier about said principal 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 axially relative to said housing.
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 about a tool axis;
- an orbital drive disposed in said housing and configured for rotating said spindle unit about an axis offset from the tool axis;
- 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;
- and
- said axial feed mechanism including a carrier, said carrier being non-rotatably mounted relative to said housing and being configured for movement toward and away from the object, and said carrier carrying said spindle unit and said orbital drive.
