Abstract: A dense cermet article including about 44-93% of a granular first hard phase, about 4-44% of a granular second hard phase, and about 2-20% of a metal phase, all expressed in % by volume. The first hard phase consists essentially of alumina and from 0% to less than 5% of one or more oxides selected from magnesia, zirconia, yttria, hafnia, and silica. The second hard phase consists essentially of a hard refractory carbide, nitride, or boride, or mixture or solid solution thereof. Preferred materials for inclusion in the second hard phase are titanium carbide, hafnium carbide, tantalum carbide, tantalum nitride, tungsten carbide, titanium diboride, and boron carbide. The metal phase consists essentially of a combination of nickel and aluminum having a ratio of nickel to aluminum of from about 85:15 to about 88:12, and 0-5% of an additive selected from the group consisting of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, cobalt, boron, and/or carbon.

Abstract: A polygonal lay down indexable insert having radial projection is described. The insert reduces the force required to machine by reducing the friction forces encountered in machining operations.

Abstract: A polygonal, lay down indexable cutting insert for eight feed and light depth of cut application. The insert has intermittent seating pads, chipbreaker pads, and stabilizer pads and is configured to allow coolant to be circulated across the body of the insert during cutting operations.

Abstract: A reamer having a single cutting blade with parallel clamping and seating surfaces seated in an anvil having converging radially outward extending planar surfaces for enhancing the clamping effectiveness of an installed anvil/cutting blade adjustably positioned radially by a pair of set screws angled to provide fine adjustment.

Abstract: An indexable improved force distribution cutting insert having a tapered cutting edge along its periphery with the greatest height at each corner of the insert and descending bi-directionally toward the centerline of the insert to define a resultant ridge to improve impact resistance at each corner.
