EHWA offers a wide range of PCD and CBN indexable inserts for turning. Customers who need high productivity can rely on EHWA turning tools – an economical solution with improved wear resistance, excellent surfaces, and maximum material removal volume.
We specialize in the design and engineering of special milling and indexable inserts. Machining requirements range from simple to difficult-to-machine workpieces – with regrinding and recoating service, PCD/PCBN in many grades, long tool life, and precise dimensional control.
PCD and PCBN tools for drilling and reaming processes, engineered to the material and machining task.
Alongside standard tools, EHWA manufactures special designs such as OKD circular saws, support rulers, and diamond measuring probes to customer specification.
Production: diamond particles and metal powder are sintered under high pressure and high temperature. PCD is more impact-resistant than natural diamond, extremely hard, and has a very high removal rate. Hardness 50 – 70 HV.
Application areas: non-ferrous metals, aluminum and copper alloys, composite materials, wood, and others.
Production: CBN grains and metal powder are sintered under high pressure and high temperature. CBN grain is an artificially produced synthetic material, extremely hard – only diamond is harder – and has higher thermal stability than diamond (up to 1000 °C). Enables significantly higher stock allowances and cutting speeds than conventional cutting tools. Hardness 30 – 40 HV.
Application areas: ferrous materials, various cast alloys, hardened steel, high-alloy steel grades.
Natural diamond: excellent surface finish, colorless, highest wear resistance, longest tool life, greatest thermal conductivity.
Mono diamond: alternative to natural diamond, yellow-colored, high-pressure high-temperature synthesis, more repeatable, consistent performance.
CVD diamond: comparable to natural diamond, colorless, excellent cutting-edge quality for high-precision applications, highly consistent material properties.
| Coating (EHWA code) | Color | Hardness (Hv) | Applications | Characteristics |
|---|---|---|---|---|
| TIN | Gold | 2300 | Cast iron | Simple coating, traditional for wear parts, easy identification of used tools |
| TA | Purple, grey | 3400 | Cast iron, hardened steel | Good heat and wear resistance, traditional for cutting tools |
| AC | Silver, grey | 3200 | Hardened steel, sintered steel | Best heat resistance, longer temperature stability, chemical resistance |
| EL | Dark grey | 3500 | Bearing shells and various steel grades | Better wear behavior, good chemical resistance, suited to hardened steel and bearing steel |
| TNP (new) | Anthracite | 3500 | Hardened steel, sintered steel, bearing shells | Excellent wear protection and temperature resistance, very good surfaces achievable, best coating for hardened and bearing steel |
EHWA additionally manufactures ceramic-based cutting materials – produced in a special sintering process with higher wear resistance and toughness than conventional ceramics, suited to roughing and finishing cast iron – as well as a coated CBN grade with high toughness and wear resistance for bearing steel and hardened steel grades in continuous and interrupted cuts.
