V-Type CBN Inserts
35° rhombic PCBN turning inserts for profiling, finishing and restricted component access. Compare negative VNGA and VNGM families with positive VBGW, VCGW and VCGT geometries by clearance, usable tip count and catalog size.
Use 35° Geometry Where Access Matters
The narrow V-shape provides more access to profiles, tapers, shoulders and restricted component features than broader rhombic insert shapes. Select the exact family by holder style, cutting-force direction, edge support and required approach.
External Profiling
Use V-type geometry where the tool must follow tapers, contours or shoulders with limited clearance around the component profile.
Internal Profile Turning
Positive VBGW or VCGW families can suit boring and internal profiling where lower cutting force and approach clearance are priorities.
Precision Finishing
Match nose radius, feed, tip count and PCBN grade to the finish target while maintaining enough edge support for the cut.

Positive VBGW / VCGW / VCGT
Positive V-type families reduce cutting force and improve access in profiling and internal turning setups.
- VBGW / VBMW: 5° clearance family
- VCGW / VCMW: 7° clearance family

The table reproduces the V-type dimensional symbols from the product catalog. Grade availability is not shown here because it varies by exact size and PCBN structure.
Choose the V-Type PCBN Structure
The V-type catalog range uses localized PCBN tips with selected two-tip options and a dedicated VNGM chipbreaker family.
1-Tip
Single localized PCBN tip across VNGA, VBGW, VCGW, VCGT and VNGM families.
2-Tip
Two usable PCBN tips are cataloged in selected VNGA, VBGW and VCGW sizes.
VNGM Chipbreaker
VNGM / VNMM adds chipbreaker geometry to the negative 35° rhombic platform.
Nose Radius
Catalog V-type radii span 0.2, 0.4, 0.8 and 1.6 mm depending on family and size.
Match the Grade to Material and Cutting Condition
Choose the exact PCBN grade after the V-type family, workpiece material, hardness and cutting continuity are known.
OBN45
Wear-focused direction for continuous to moderately interrupted hard turning and fine finishing.
O2C50
Abrasion-resistant direction for continuous to lightly interrupted hard machining.
OBW85
High-CBN direction for abrasive workpieces, selected cast-iron applications and more demanding interruption.
Confirm by Code
Exact grade availability varies by V-type size and PCBN structure. Confirm the final combination before ordering.
Where V-Type PCBN Inserts Fit
Use V-type geometry when profile access is the main geometric requirement, then choose grade and tip structure by material, hardness and cutting continuity.
Hardened-Steel Profiling
Use VNGA or positive V-type families for contours, tapers and shoulders in hardened components, then select the grade by hardness and interruption.
CBN Inserts for Hard Turning →Cast Iron Profiles
Use VBGW or VCGW where cast-iron components need 35° profile access and a positive cutting geometry.
CBN Inserts for Cast Iron →CBN Tipped Structures
Compare 1N, 2N and chipbreaker structures across the broader CBN tipped insert range.
Browse CBN Tipped Inserts →What to Send for V-Type Insert Selection
Send the complete insert requirement and machining condition so the 35° family, size, tip count and grade can be checked together.
