A modular countersink assembly, comprising:
- a drill having a centerline and an exterior tapered surface;
- a countersink body having an interior tapered surface, the countersink body being removably secured to the drill to mate the interior tapered surface in seated engagement with the exterior tapered surface of the drill;
- and
- an insert removably secured to the countersink body, the insert and the countersink body being positioned axially and radially to the centerline of the drill.
A modular countersink assembly, comprising:
- a drill comprising a drill body and a drill shank, the drill having an exterior tapered surface joining the drill body and the drill shank;
- a countersink body removably secured to the drill by at least one set screw, the countersink body has an interior tapered surface for mating with the exterior tapered surface of the drill in seated engagement;
- and
- an insert removably secured to the countersink body, wherein the drill shank has opposing flats having a back taper for engaging the at least one set screw for removably securing the countersink body.
A drill for use in a modular countersink assembly, the drill comprising:
- a drill body having a flat for receiving a cutting insert in an abutting engagement;
- a drill shank having opposing flats, the opposing flats having a back taper;
- and
- a tapered surface transitioning from the drill body to the drill shank, the tapered surface for mating with an interior tapered surface of a countersink body.
