Metalforming

Kennametal offers a wide range of metalforming products, including heading dies, EDM blocks, specialty blanks, and wire, bar, and tub drawing.

Heading Dies

Cold-forming tools like heading dies are designed to sustain high and repeated stress. Tungsten carbide makes the use of cold-forming technology possible for mass production of high-volume parts like screws, bolts, and rivets. Kennametal’s specialty grades make it possible for our heading dies to last a long time and deliver superior part accuracy.

Features and Benefits

• Standard offering in sintered unground condition, with optional skim grinding of outside diameter

• Greatly improved dimensional consistency of parts due to excellent transverse rupture strength and pressure resistance

• Sizes Ø8mm x 6mm to Ø60mm x 100mm height

• Uniform binder phase and content means substantially higher overall strength

• Custom die blanks, semi-finished & finished dies are available by request

• Outstanding tool life and wear resistance

EDM Blocks

Kennametal offers a large selection of conventional and low-corrosion rectangular EDM blanks in stock. Blocks are available in standard sizes and are individually packaged for easy delivery and handling.

Withstand Extensive EDM
Our latest grades for EDM blocks were developed with a proprietary binder system and maintain the hardness and mechanical properties of our conventional grades. They resist the corrosion, pitting, and cracking commonly experienced during electrical discharge machining, especially in thick punches and large die segments.

Wire, Bar, and Tube Drawing

The wire, bar, and tube drawing process creates challenging friction conditions from the high flow speeds of the carbide through the die. Kennametal offers tungsten carbide that has exceptionally high strength and excellent performance in these high-friction conditions. Our carbide is available in a range of grades and in die pellets in the following sizes:

  • Drawing wire from Ø0.2 to 70mm
  • Drawing steel and non-ferrous bars from Ø10 to 75mm
  • Drawing tubes from Ø10 to 120mm
  • All die pellets available according to ISO standards

Specialty Blanks

We offer a wide assortment specialty blanks, including:

  • preformed and unfinished tools, dies, die sections and components made from tungsten carbide
  • a range of grades from submicron to extra-coarse
  • a variety of leading edge binder formulas

 Kennametal specially engineered tungsten carbide components can last more than 10 times longer than steel in most applications.

We engineer our carbide components from a wide assortment of grades so you get the right grade for the right job. Our flexible manufacturing capability means we can make anything from the simplest part to complex custom shapes.

We also can develop and test new tungsten carbide grades that are tailored to your specific needs.
