Abstract: The present invention relates to cutting tools with cutting inserts and, more particularly, to cutting tools with cutting inserts that have mounting recesses. The cutting insert includes a body having a mounting hole having an axis extending therethrough, and a surface portion in the mounting hole. The surface portion is substantially circular when viewed in a direction of the axis and is non-parallel to the axis and including at least two contact points disposed at a lesser distance from the axis than a region between the at least two contact points. A cutting tool is also disclosed.

Abstract: The present invention relates to cutting tools with cutting inserts and, more particularly, to cutting inserts having adjusted cutting edges. The cutting insert comprises a virtual clearance surface that is one of substantially flat and planar and substantially frustoconical. The virtual clearance surface forms a non-zero angle with a perpendicular to a virtual plane of a top surface of the insert. A first virtual cutting edge is disposed above the virtual clearance surface. All points on the first virtual cutting edge are disposed at the plane of the top surface. An adjusted clearance surface differs from the virtual clearance surface and forms the non-zero angle with the perpendicular to the plane of the top surface. An adjusted cutting edge above the adjusted clearance surface, at least some but fewer than all points on the adjusted cutting edge are disposed at different distances from the plane of the top surface.

Abstract: The present invention relates to a cutting tool and a cutting insert. The tool includes a toolholder and at least one insert adapted for mounting relative to the toolholder. The at least one insert includes at least one chip removal channel.

Abstract: An indexable insert includes an insert body including a plurality of cutting edge portions and an insert hole arrangement for permitting the insert to be secured to a toolholder. The insert hole arrangement includes at least one securing screw-receiving hole. The insert hole arrangement is configured to permit a securing screw to extend through the insert body along any one of at least two different axes through the insert hole arrangement, the insert hole arrangement including a screw abutment surface for abutting against the securing screw.

Abstract: A cutting tool for, e.g., dressing electrode tips includes a toolholder having an opening extending through the toolholder from a top of the toolholder to a bottom of the toolholder along a central axis of the toolholder, and a plurality of insert mounting pockets disposed around the opening for mounting replaceable cutting inserts, the plurality of insert mounting pockets including a center pocket, a top pocket, and a bottom pocket. The tool also includes a center insert removably disposed in the center pocket, a top insert removably disposed in the top pocket, and a bottom insert removably disposed in the bottom pocket. When a top electrode tip and a bottom electrode tip are disposed in a dressing position relative to a top and a bottom of the opening in the toolholder and the tool is rotated, the center insert and the top insert dress the top electrode tip, and the center insert and the bottom insert dress the bottom electrode tip.
