ABSTRACT:
A counterbore tool having a removable cutting tool in which the cutting tool is disposed in an open slot of the shank, the slot extending inwardly from the outer extremity of the shank and in which the pilot member is secured in telescoping engagement with the end of the shank, the pilot member being detachably held by fastening means which clamps the pilot member against the cutting tool and holds it firmly in place. The cutting tool has a transverse depth equal to the width of the slot so as to fit snugly within the slot. The cutting tool and shank are provided with interfitting male and female members which prevent movement of the cutting tool transverse to the axis of the shank. The pilot member snugly telescopes over the shank and is provided with a slot extending over the outer side edge of the cutting tool. The clamping means for clamping the pilot member onto the shank member and against the cutting tool preferably comprises two screw threaded fastening members disposed on opposite sides of the axial center of the pilot member so that the clamping means also resists any tendency of the pilot member to turn about the axis of the shank. The slot through the pilot member extends for the full width thereof so that it engages the cutting tool for the full width of the pilot member. The interfitting male and female portions of the shank and cutting tool take the form of a stud in projecting outwardly from the base of the slot in the shank and a slot in the cutting tool which fits over and closely engages the stud pin.
The cutting tool preferably has two oppositely disposed portions. The rake and relief angles are preferably so selected that the cutting tool is of a uniform length throughout its width so that the cutting edges of the cutting portion may be sharpened without altering the radius of the counterbore produced by operation of the tool.
