Tools with Polycrystalline Diamond (PCD) blanks are designed to machine non-ferrous and non-metallic materials at high speeds. They've proved they can outperform many ordinary tools in production applications. Tools with Polycrystalline Diamond blanks are made by brazing "PCD" blanks to steel shanks, then grinding the tool point to its final configuration with diamond wheels.

INTERRUPTED CUTS ARE NO PROBLEM

Because of their high resistance to shock and vibration, tools with "PCD" blanks are being successfully applied in tough machining applications, such as work-pieces with interrupted cuts, that often cause ordinary tools to break down. And tools with "PCD" blanks can handle work-pieces that have hard inclusions which cause excessive edge wear on ordinary tools. Even when machining abrasive silicon-aluminum alloys, tools with "PCD" blanks may have useful lives of 100,000 pieces or more--hundreds of times more life than cemented carbide tools.

SHARP EDGES CUT COST

Tools with "PCD" blanks tend to keep their sharp edges, even when removing material at rates far above those possible with cemented carbide tools. This means that close dimensional and surface finish tolerances can be held through long production runs.

With higher material-removal rates and fewer tool changes, the productivity of men and machines is improved dramatically, reducing labor-and-overhead cost per piece.

Although tools with "PCD" blanks may be priced higher than ordinary tools, they last so much longer that tool cost per piece can still be lower. And up lower machining costs and lower tool cost--and you get higher profit per piece.

NOT JUST FOR TURNING

With the many shapes and sizes now available, "PCD" tool blanks have an almost unlimited range of machining applications. Examples are milling, grooving, parting, even reaming. The possibilities depend on your needs, and are limited only by your imagination.

THE ADDED BENEFITS--more pieces per hour, less machine downtime, higher part quality and less scrap--results in even greater savings.
