Dennis Tool Company manufactures a complete line of specialized superabrasive products for tooling used in automotive, aerospace, electronic, woodworking and other major industries. Principal products include high-pressure high-temperature (HPHT) materials such as polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PCBN); as well as advanced microwave sintered carbides, and related diamond/carbide composites. Dennis Tool Company is committed to delivering consistently high quality PCD and PCBN products at competitive prices, and devotes an extraordinary level of research and engineering to both product development and advanced manufacturing technology.

PCD and PCBN continue to replace tungsten carbide in a wide range of industrial applications. In metal machining applications, typical performance is 100X to 500X that of carbide tooling, with improvement in the workpiece surface finish.

The economics of sophisticated computer controlled machining centers and transfer lines demand longer runs of close tolerance parts. Improvements in the performance of PCD and PCBN are additionally driving the increased use of difficult to machine high performance materials such as high silicon aluminum, glass reinforced resins, pressboard laminates, metal matrix composites, and woven graphite composites. Dennis Tool Company is at the forefront of superabrasive material development.
