Brand Innovation: Developed by Kyocera to provide a highly stable alternative to carbide tools during high-speed machining.
Shape Configuration: Standardized V-shape with a 35-degree included angle to facilitate deep profiling and undercut clearance.
Clearance Angle: Features an N-type negative zero-degree clearance angle, providing exceptional edge strength across four usable cutting corners.
Tolerance Designation: Adheres to the M-class precision tolerance standard for highly predictable centerline indexing during insert swaps.
Fixing Geometry: Built with a G-type cylindrical clamping hole to ensure solid anchoring inside rigid top-clamp tool holders.
Edge Sizing: Standardized 16 mm structural cutting edge length to fit heavy-duty external and internal turning bars.
Body Thickness: Designated by the 04 dimension code, translating to a uniform thickness parameter of exactly 4.76 mm.
Nose Radius: Built with a 0.4 mm corner radius, which lowers radial cutting force to minimize vibration on thin shafts.
Substrate Synthesis: Composed of TiCN, TiC, and TiN ceramic elements bound in a tough metal matrix.
Edge Sharpness: “The TN60 grade provides excellent wear resistance, toughness, and thermal stability…” ensuring a crisp edge that prevents micro-chipping.
Surface Polish: “Cermet (Ceramic + Metal) technology delivers a smooth, stable cutting edge that minimizes friction and built-up edge (BUE)…” for high-gloss surface results.
Anti-Welding Nature: High chemical resistance prevents steel molecules from welding to the tip, stopping built-up edge formation.
Material Focus: Optimally applied to continuous, high-speed turning of mild steels, forging steels, and carbon steels.
Machining Phase: Specially restricted to light-duty final finishing runs where dimensional consistency is highly critical.
Economic Value: “The versatile VNMG geometry… provides strong, reliable performance with excellent dimensional accuracy.” delivering 4 distinct edges per insert for lower costs.
