Kennametal’s round tool product business focuses on delivering high-performance cemented carbide blanks with precise dimensional and metallurgical accuracy. This ensures efficient production for tool makers and automated manufacturing plants. The company emphasizes productivity, innovation, and consistent quality, building a global reputation for reliability. By collaborating closely with tool makers and users, Kennametal develops advanced materials and processes that enhance tool performance. Its proprietary grades—made from high-purity raw materials—resist corrosion and improve coating adhesion, contributing to superior durability and effectiveness of cutting tools.
Fits and Tolerances
Kennametal’s rod blank portfolio offers a variety of ground and unground rod blanks.
Unground
• Ideal for custom tooling and tool sizes that are not standard/nominal sizes.
Unground blanks are also considered for certain non-rotating applications.
Ground to h6
- Well suited for applications with tight tolerances and precision cuts. The lowercase
“h” indicates the shaft-based fi t for rod blanks, with exclusively negative tolerances.
“h” indicates the shaft-based fi t for rod blanks, with exclusively negative tolerances. - The number following the “h” indicates the tolerance range.
- (+0.0000, -0.000X)
Ground Micro finish
• Delivers an aesthetically pleasing mirror polish.
EXPERIENCE
At Kennametal, we strive to offer our customers outstanding
performance in everything we do and solve our customers’ most
complex wear and performance problems. We work closely with
tool makers and tool users to increase productivity and decrease
complexity for next-level metalcutting.
QUALITY
Kennametal provides high-performance cemented carbide blanks
with high accuracy in dimensions and metallurgical properties. This
advantage ensures smooth and fl awless processing for tool makers
and highly automated drill and end mill manufacturing plants.
Our grades are made of high-purity raw materials, ensuring
consistency in performance. Our proprietary grades and binder
phase formulations prevent staining and corrosion caused by
air moisture, grinding coolant, and other conditions in
working environments.
CONSISTENCY
Kennametal blanks have a strong reputation worldwide for their
consistent metallurgical properties and dimensional accuracy.
We constantly innovate carbide blanks (hardmetal) and continue
to develop new processes and materials to make users’ projects
a cut above the rest.
