Abstract
A beveler device is configured for removable attachment to a hand-held power unit and to simultaneously de-burr and bevel the raw cut edge of a PVC pipe. An adapter may be attached to the beveler device and connect a vacuum hose for suction of chips and debris into the interior of the beveler device and out through the vacuum hose during operation.
Claims12
A beveler device, comprising:
- an adapter configured to removably attach the beveler device to a hand-held power tool operable to rotate a bit about an axis of rotation, to simultaneously de-burr and bevel a cut edge of a plastic pipe when engaged with said cut edge;
- an adjustment ring, the adjustment ring configured to fit over and be connected to the adaptor and including a slot, wherein a connection of the adjustment ring to the adaptor through the slot determines the position of the adjustment ring in the direction parallel to the axis of rotation of the bit;
- a guide plate, the guide plate configured so that the face of the guide plate lies in a plane perpendicular to the axis of rotation, the bit partially protruding from a hole in the center of the guide plate, the amount of said bit protruding from the hole in the center of said guide plate being adjusted by loosening an adjustment screw and manually adjusting the location of said guide plate along the axis of rotation of the bit;
- and
- a vacuum attachment, said vacuum attachment being removably attached to said beveler device and connecting a vacuum hose to suck chips and debris through the hole in the center of the guide plate, the interior of said adjustment ring, and out through the vacuum hose.

A beveler device, comprising:
- an adaptor, said adaptor configured to attach said beveler device to a hand-held power tool, the hand-held power tool configured to receive, secure and rotate a working tool about an axis of rotation;
- an adjustment ring, the adjustment ring configured to fit over the adaptor and including an adjustment slot having a length extending in a direction parallel to the axis of rotation and a width extending in a direction perpendicular to the axis of rotation;
- an adjustment screw, the adjustment screw having a diameter smaller than the width of the adjustment slot in the adjustment ring and fitting into a threaded hole of the adaptor and, when tightened, the adjustment screw connects the adjustment ring to the adaptor;
- a guide plate having a flat face and attached to the adjustment ring so that the flat face of the guide plate lies in a plane perpendicular to the axis of rotation, the guide plate having a hole centered on the axis of rotation;
- and
- a shroud, fitting within and directly abutting said adjustment ring, and protruding through the hole in the guide plate,
- wherein the position of said flat face of said guide plate relative to the hand-held power tool and a working tool secured in the power tool in the direction of the axis of rotation is determined by the position of the adjustment screw along the length of the adjustment slot in the adjustment ring when the adjustment screw is tightened.
