Hitachi WDNW 09T320 JP4020

Meet the Hitachi WDNW09T320 JP4020 – engineered for high-performance machining with real cost savings.

• Get longer tool life and fewer insert changes – which means less downtime and higher productivity.

• Achieve faster cutting or more stable feeds even on tougher materials, lowering the cost per component.

• Produce better surface finish and dimensional consistency thanks to the high-quality grade and geometry.

• Insert code: WDNW09T320 with grade JP4020 (Hitachi/Moldino) – targeted at hardened steel (≈ 40–55 HRC), cast iron, stainless and general engineering materials. 

• Geometry: W-shape (80° diamond style) indicated by the “WDNW” series; allows strong edge and stable turning/milling performance.

• Insert size: Approx. 9.525 mm inscribed circle, thickness ~3.97 mm; corner radius typically ~2.0 mm for this variant. 

• Coating / grade: JP4020 grade from Hitachi signifies high-performance coated carbide for more demanding work-piece materials.

• Applications: Ideal for turning, milling, even drilling/roughing when the toolholder supports the geometry; especially effective on hardened steel, cast iron and tough alloys.

• Because it lets machinists run longer between changes – fewer insert swaps, less setup time.

• Because it gives consistent surface finish and less scrap – your parts meet spec more reliably, rework drops.

• Because it holds up better under wear, especially when working hardened or interrupted cuts – giving you high wear resistance and therefore lower cost-per‐part.

• Automotive: engine blocks, housings, high-hardness transmission components.

• Aerospace: structural steel parts, hardened housings, cast components.

• Die & Mould: high-hardness steels, cast stainless dies.

• General Engineering: cast iron components, stainless assemblies, high-volume production runs.
