About VN 35° Zero-Rake Diamond Inserts (VN-Style)

The ISO 1832 VN-shape family delivers a 35° rhombic cutting edge with 0° clearance angle — the strongest and most negative-rake variant in the 35° diamond family. Mitsubishi's VN lineup includes two main geometry variants:

• VNMG (M chip-breaker, M tolerance) — 24 SKUs. The workhorse 35° zero-rake negative with chip-breaker on both faces. Available in IC 16.0 mm, nose radius 0.4 / 0.8 / 1.2 mm, with multiple chip-breaker variants: MA (general), MS (medium semi-finish), GK (heavy), MP (medium profiling), SH (sharp).
• VNGG (G chip-breaker, G tolerance) — 3 SKUs. Ground-periphery cermet finishing insert with chip-breaker on one face. Premium 35° zero-rake for mirror surface work on steel and stainless.

VN inserts are the strongest edge in the 35° diamond family — 0° clearance means the insert sits flat on the holder without any rake angle, providing maximum edge support for heavy interrupted cuts and cast iron roughing. Compared to other 35° diamond shapes: VB (5° positive) is sharper, VC (7° negative) is balanced, VN (0° zero-rake) is the strongest. Common applications include heavy profiling of small-diameter stainless shafts, cast iron free-cutting, and roughing where edge chipping is a concern.

Mitsubishi's VN catalog is rich in cast iron coverage — UC5115 (CVD K-grade) is heavily represented (6+ SKUs at IC 16 mm). Steel and stainless steel are well-covered with UE6020 / UE6110 / UE6105 (P-grade) and US735 (M-grade). The 16.0 mm IC is the only size in the catalog — the 35° geometry typically doesn't go below 11 mm or above 16 mm due to grinding complexity.

• Cermet (Finishing) — NX2525 (P05-P15, mirror surface)

By Chip-Breaker

• MA (Medium All-round): General purpose, the most common (8+ SKUs across all grades).
• MS (Medium Semi-finishing): Lighter chip-breaker for finishing and stainless profiling.
• GK (General Heavy): Stronger chip-breaker for roughing of cast iron.
• MP (Medium Profiling): Optimized for profiling operations.
• SH (Sharp): Used on cermet NX2525 for steel finishing.

How to Choose the Right VN 35° Zero-Rake Insert — 3-Step

Step 1 — Identify the Workpiece

• Cast iron (gray, ductile, CGI): VNMG with UC5115 grade (K-grade CVD) or MC5015 / MC6025 for high-speed.
• Stainless steel 304/316 (interrupted): VNMG-MS or VNMG-MA with US735 grade (M-grade CVD coated for stainless).
• Carbon steel / alloy steel: VNMG-MA with UE6020 (P20-P30) or UE6110 (P15-P25 high-speed).
• Mirror finishing on steel: VNGG-F with NX2525 cermet (ground periphery for maximum sharpness).
• Universal (steel + stainless): VNMG-MA with VP15TF PVD Miracle Coat.

Step 2 — Pick the Chip-Breaker

• MA (Medium All-round): General purpose, most common.
• MS (Medium Semi-finishing): Lighter chip-breaker for finishing.
• GK (General Heavy): Stronger edge for roughing and interrupted cuts.
• MP (Medium Profiling): Optimized for profiling operations.
• SH (Sharp): Used on cermet NX2525 for steel finishing.

Step 3 — Verify Holder Compatibility

• VN (35° zero-rake negative): Use MVJN-type holders (multi-lock, 35° lead angle). 0° clearance means the insert sits flat without any rake.
• Verify lead angle: 35° matches VNMG perfectly. Common holder: MVJNR/L 2525-M16 (16 mm IC).
• Match IC to holder pocket: VNMG 16 needs 16 mm pocket (only size in catalog).
