Kyocera VNMG160402GP TN60

Cut more parts per insert. Get up to 30–50 % longer tool life while raising your surface finish standards — and lower your per-piece cost.

• Geometry & shape: VNMG style, 35° diamond (rhombic) insert, neutral (no handedness) design, with 4 usable cutting corners. 

• Insert dimensions: “1604 / 02” designation implies ~16 mm cutting edge length (approx. 16.606 mm) and ~4.76 mm insert thickness. 

• Corner radius: Often a small radius (e.g. r = 0.2 mm) for fine finishing.

• Rake / orientation: Negative (flat) insert with a negative rake design, suitable for stable finishing under continuous cuts.

• Material / grade: TN60 cermet (uncoated) — combines ceramic hardness with metallic toughness, optimized for steel & stainless finishing. 

• Cutting applications: Mainly turning (OD / ID), facing, finishing cuts — ideal for smooth surfaces, low feed, light depths.

• Longer tool life, less downtime — thanks to TN60’s wear resistance, you can run finishing passes longer before needing insert change.

• Superior surface finish — the sharpness and stable geometry help reduce scalloping and chatter — fewer rejects, less polishing.

• Stable performance in steels & SS — its toughness resists micro-chipping when machining hard or interrupted surfaces.

• Cost efficiency per component — fewer insert changes, reduced setup time, and better yield means lower overall cost per part.

• Widely trusted — because many production shops and OEMs specify Kyocera’s TN60 for finishing, it has built a reputation for reliability.

This insert is suitable for a wide range of sectors:

• Automotive (shaft finishing, bearing journals, engine parts)

• Aerospace (precision steel & stainless components)

• Die & mold (fine finishes, tight tolerances)

• General engineering & fabrication (rollers, shafts, hydraulic parts, etc.)
