Abstract
A tool for use with a rotary drive is provided with a number of differently formed slots therein to receive different cutting blades in various orientations. The tool is adaptable for cutting in a radial direction and in an axial direction and can accommodate molding head cutters as well as standard 1/4-inch tool steel bits in various combinations with spacer bars to provide different cutting profiles in a radial direction and to permit surface boring and milling in the axial direction.
Claims19
A tool for use with a rotary drive for cutting a workpiece, comprising:
- a disc-shaped body having centrally located means for mounting to the rotary drive and defining an axis of rotation;
- a first plurality of elongate (apertures) slots formed substantially radially in said disc-shaped body and passing through from one side to the other side of said disc-shaped body and being adapted for receiving a first tool bit in each of said first plurality of slots;
- each of said first plurality of slots being elongated to have a length substantially greater than a width of said first tool bit to permit said first tool bit to be positioned at preselected points along the length of said first elongate slot;
- a second plurality of slots formed in the rim of the said disc-shaped body pointing generally ouwardly from the center of said disc-shaped body and being adapted for receiving a second tool bit in each slot;
- and
- a third plurality of slots formed in one side of said body and the rim of said disc-shaped body and not extending through said body and pointing generally outwardly from the center of said body and being adapted for receiving at least one of the first tool bits in each slot, whereby upon said disc-shaped body being mounted to the rotary drive and a first tool bit being arranged in each of said first plurality of slots the tool is adapted for axial cutting and upon a second tool bit being arranged in each of said second plurality of slots, the tool is adapted for radial cutting and upon at least one of the first tool bits being arranged in each of said third plurality of slots the tool is adapted for radial cutting of the workpiece.

A device for attachment to a rotating drive shaft, comprising:
- a flat body member having two flat surfaces and outer peripheral edges and with a central axis of rotation substantially perpendicular to said flat surfaces and having first, second, and third plurality of slots formed therein,
- said first plurality of slots being formed completely through said flat body member from one flat surface to the other flat surface so as to define inner central hub walls and outer rim walls in said flat body member, each of said plurality of slots being of a length to receive cutting tool bits therein at any point along the length of the slot, the tool bits being arranged in substantially the direction of the central axis of rotation,
- said second plurality of slots formed in outer peripheral edges of said flat body member being in spaced-apart relationship with said first plurality of slots arranged radiating outwardly from said central axis of rotation and being adapted to receive molding cutter blades therein,
- said third plurality of slots formed in said outer peipheral edges of said flat body member being in spaced-apart relationship to said first and second plurality of slots arranged radiating outwardly from said central axis of rotation including means to form a floor member for said third plurality of slots and being formed having a depth to receive a plurality of cutting tool bits and bar-shaped spacer means therein arranged parallel to the flat surfaces of said flat body member,
- whereby when tool bits and spacer means are placed in said slots, the device is attached to the rotary drive shaft, and rotated in contact with a workpiece, the workpiece is cut.
