Kennametal EDM Blocks

Tungsten carbide grades serving the industry for over 40 years.

Industry leading grades proven in their application. We use a proprietary process which results in mechanical properties that resist corrosion, pitting and cracking commonly experienced during electrical discharge machining.

Grades That Punch Back

Kennametal EDM Blocks are made by a proprietary stress-relieving sinter-HIP process. Optimized metallurgy ensures pits or cracks won't slow you down.

Our latest grades include the KR Series. KR Grades feature a mix binder that provides corrosion resistance to help reduce EDM times and number of skim cuts.

Our proven grades ensure consistent, reliable performance while stamping a wide range of metals, from silicon steel to beryllium copper, and everything in between.

The right sizes and grades now available for online purchase!
