Abstract
A cutting tool which may comprise: an elongated bar member; an anvil member removably fastened to one end of the bar member and having an elongated recess in which a cutting insert may be received; and a clamp member removably fastened to the anvil member for rigidly clamping the cutting insert in the elongated recess. The elongated bar member and anvil member may be provided with cooperating key and keyway by which the anvil member is at least partially affixed to the bar member in a predetermined rigid position.
Claims18
A cutting tool comprising:
- an elongated bar member;
- an anvil member removably fastened to one end of said bar member and having an elongated recess in which a cutting insert may be received;
- and
- a clamp member removably fastened to said anvil member for rigidly clamping said cutting insert in said elongated recess;
- said bar member being provided with a bottom threaded hole having a smooth counterbore of larger diameter, said anvil member being provided with a smooth bore hole of substantially the same diameter of said counterbore;
- said anvil member being at least partially fastened to said bar member by a screw member having a threaded end for engagement with the threaded portion of said threaded hole and a smooth cylindrical portion for disposition within said smooth counterbore and said anvil member smooth bore hole.

A cutting tool comprising:
- an elongated bar member having keyway means at one end thereof whose longitudinal axis is substantially perpendicular to the longitudinal axis of said bar member;
- an anvil member removably fastened at said one end of said bar member having key means for engaging said bar member keyway means and having an elongated recess in which a cutting insert may be received;
- fastener means for removably fastening said anvil member to said bar member, said fastening means and said key and keyway means cooperating to rigidly affix said anvil member to said bar member;
- and
- clamp means removably fastened to said anvil member for rigidly clamping said cutting insert in said elongated recess;
- said fastener means comprising a first hole in said bar member, a coaxially aligned smooth bore second hole through said anvil member and a screw member, the bottom of said first hole being threaded and the top of said first hole being counterbored to provide a smooth counterbore of substantially the same diameter of said second hole, the end of said screw member being correlatively threaded to engage said threaded bottom of said first hole, the remaining shank of said screw having a smooth cylindrical surface for close tolerance disposition within said first hole counterbore and said second hole.
