we offers a wide range of custom and standard cutting tool carbide blanks

Our tungsten carbide rod blanks are available in a wide selection of micro-grain and sub-micron grades that are engineered to stand up to thermal extremes, vibration, and impact wear. Our products are sinter-HIP processed for ISO 900:2015 certified manufacturing facilities.

We offer:

pressed and extruded unground, ground and polished rods with or without chamfers

rod products that can be ground to h6 tolerances

a variety of grades that provide exceptional wear and impact resistance

grades for use in end mills, reamers, drills, countersinks, engraving tools, routers, and other rotary tools

grades for use in a broad range of applications in almost any material

Cut-to-Length (CTL) Rod

We have one of the largest and most complete lines of ground CTL selections in the industry. Premium grades, standard and micro-finished surface finish, and h6 ISO diameter tolerances in inch and metric lengths and diameters. Special preform features are available, including male center, female center, ballnose, step reduction, and shaped points.

Solid Rods and Rods with Coolant

Kennametal manufactures 12” (330mm) length rods with single hold, straight two-hole, in diameters from 2mm to 40mm. High-performance gun drill rod blanks are available.
