Grade 2210 – The Industry Standard for Carbide Rod Blanks
Our best general-purpose grade for use in rotary tool blanks.
A 10% cobalt grade that combines exceptional wear and impact resistance for a broad range of applications, including end mills, reamers, drills, and other rotary tools.
Lengths: 12″ standard, cut-to-length, or pressed-to-length.
Diameters: Multiple sizes in both inch and metric.
Finishes: Choose from ground, unground, or micro-finish.
Rods can be ground to h6 tolerances.
Cutting Tool Blanks
Metal Cutting Tool Blanks
We have a complete line of metal cutting tool blanks in a wide selection of tungsten carbide grades with binders ranging from 5.5% to 25%, and grain sizes to suit your application. Straight tungsten carbide cobalt binder grades, as well as mixed tungsten carbide grades with additives of titanium carbide to prevent galling in metal-to-metal wear, are available.
Insert Blanks
We can provide a wide range of standard indexable insert blanks like FSNG, SNR, SPR, TNR, TNRA, TNRC, TPR, TPS, UVDB, plus special geometries custom-engineered to your specifications. Most inserts are pressed to size with minimum grind stock to keep your finishing costs low.
Flat Blanks
We can provide a variety of standard toolmaker blanks, including styles K1000 through K6000, and STB blanks, plus special geometries custom engineered to your specs.
Rod Blanks
Kennametal’s 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 9002 certified manufacturing facilities.

Mill Rolls
Composite Rolls with Easy-to-Use Clamping System
Kennametal composite mill roll assemblies are designed for use in the high torque, low speed (<10m/sec), intermediate strands of wire rod mills where traditional cast iron or PM steel rolls are used. These roll assemblies are supplied in two axial clamping systems – a traditional hydraulic clamp and our new mechanical clamp that’s easy to install and maintain. Our mechanical clamp provides clamping forces equivalent to hydraulically clamped assemblies, but without the need for specialized tools or fluid.
Kennametal’s new Patented Mech-Lock Combi Roll brings cutting edge technology to run for years. Intermediate stands requirement of rolling of wire and rebar is met with carbide grades RCV5 & RCV6, best suited for Combi. We take key initiatives to make Combi, a running success story at demanding environments. Kennametal partners with customers for its effective implementation.
Intermediate & Pre-Finishing (Cantilever) Stand Rolls
Medium to heavy pass reduction takes place in these stands. Rolling speed is generally low, thermal fatigue is high and roll cooling is not as effective as that in block mills. Hence, the rolling conditions are severe and demand very high toughness for withstanding the rolling load, good resistance to rolling, corrosion wear and good thermal conductivity. Kennametal grades with binder percentage between 20% and 30% are preferred. Selection of binder depends on the water quality and discharge.
3 Roll Mills
Three rolls are placed at 120 degrees. Round or hexagon-shaped wires or rods are rolled. Kennametal grades between 25% and 30% binders are preferred. Selection of binder depends on the water quality and discharge.
Block Mill Rolls
Quality of the wire or rod is decided by these rolls. These rolls demand very high resistance to wear and thermal fatigue. Performances of the rolls are determined in terms of tonnage rolled per pass. Kennametal grades between 12% and 20% binders are preferred. Selection of binder depends on the water quality and discharge.
Pinch Rolls
Pinch rolls are non-reducing rolls which demand good wear resistance without breakage. In most cases, rolls are not cooled, or no effective cooling exists. This can be offered in solid carbide, steel and carbide version. Kennametal grades between 25% and 30% binders are preferred.
