Abstract: Small size insert and insert-blank apparatus for machine tools for grooving and turning have a body with generally parallel and opposing sides, and top and bottom surfaces which have at least a portion thereof inclined from adjacent a first end to the opposite end, and two heads extending from opposite ends of the body, each head having a rear end with which the body forms portions adapted to serve as stops to prevent rearward movement with respect to the machine tool when use. The body of the apparatus is adapted to be mounted in a toolholder having a nest or pocket having an inclined bottom wall which cooperates with the inclined portion of the bottom surface of the apparatus, and a clamp secured to the toolholder having a finger portion cooperative with the inclined portion of the top surface of the apparatus to resist forces on the apparatus during turning.

Small size insert and insert-blank apparatus optionally have at least one head having a rear end and a body extending from the rear end of the head having top and bottom surfaces with inclined portions intersecting the rear end of the head forming portions adapted to serve as stops to prevent rearward movement with respect to the machine tool when in use.

Abstract: A small size insert for use with a machine tool for grooving, boring and turning and adapted to be received in a toolholder has an arcuate surface portion and a substantially arcuate-shaped shoulder integral with the body of the insert for accurately positioning the insert within a toolholder.

Abstract: A tool support adapted for use with a tool holder having an elongated shank which is mounted in a machine tool, is useful to support an insert for cutting deep grooves in a workpiece. The tool support has a body having a central body portion and a second body portion extending from the central body portion, which second body portion has a first surface portion adapted to support an insert thereon and a second portion extending arcuately from the first surface portion which is adapted to enter arcuate or circular spaces or grooves formed by the tool in a workpiece. The body portions are preferably integral and preferably includes a portion which engages the tool holder and inhibits vertical movement of the tool support relative to the tool holder and a third body portion adapted to cooperate with a clamping member to clamp the insert to the tool support.
