W-Type CBN Inserts
80° trigon PCBN turning inserts for stable external and internal turning. Compare WNGA, WNGM and WCGW families by negative or positive geometry, 1N or 3N tip structure, chipbreaker configuration and catalog size.
Choose W-Type Inserts by Usable PCBN Corners
The trigon body is attractive when stable turning and cost per usable PCBN corner matter. The ONMY catalog currently lists 1N and selected 3N structures; choose the tip count only where the holder and workpiece allow every cutting position to be used.
1N Structure
One localized PCBN tip for straightforward orientation and application-specific edge use.
3N Structure
Three usable PCBN tips are cataloged in selected WNGA / WNMA and WCGW / WCMW 0804 sizes.
Cost per Usable Edge
Evaluate usable tip count together with holder access, edge preparation, interruption and the actual machining cycle.
Choose a Trigon PCBN Insert Family
The W-type catalog range combines negative WNGA, negative chipbreaker WNGM, positive WCGW and a selected full-face WCGW-F structure.
WNGA / WNMA
Core negative 80° trigon family with 1N and selected 3N PCBN tip structures.

WNGA080408 at a Glance
WNGA080408 is one of the clearest transactional search codes in the W-type SERP. The values below come from the ONMY catalog and should be matched to the required PCBN tip structure and grade before ordering.
WNGA 080408
Negative 80° trigon PCBN insert available in the ONMY catalog as both 1N and 3N structures. Use the 3N version only where all three PCBN corners are accessible in the holder and machining cycle.
Select W-Type Geometry by Edge Support and Cutting Force
Current SERP product pages strongly center WNGA as a negative 80° trigon PCBN platform. The ONMY range also includes positive WCGW, so choose the body style according to holder geometry, cutting force, component access and required edge support.
Negative WNGA / WNGM
Negative trigon bodies provide a stable platform for external and internal turning where edge support is important.
- WNGA / WNMA: 1N and selected 3N structures
- WNGM / WNMM: chipbreaker family
- 0804 and 1006 size platforms
- Use the actual cutting continuity to choose the PCBN grade
Positive WCGW
Positive WCGW / WCMW provides an alternative trigon body where lower cutting force is preferred.
- 1N and selected 3N structures
- 0804 sizes in the tipped family
- WCGW-F / WCMW-F full-face option
- Confirm holder compatibility before switching from negative WNGA

Confirm by Code
Exact grade availability varies by W-type size and structure. Confirm the final combination before ordering.
Where W-Type PCBN Inserts Fit
Current WNGA SERP results center hardened steel, cast iron and stable turning applications. Use trigon geometry for the required holder approach and usable-corner strategy, then select grade and edge condition by the actual cut.
Hard Turning
Use WNGA or WNGM for hardened-steel turning where a stable negative trigon platform and suitable interruption capability are required.
CBN Inserts for Hard Turning →Cast Iron Machining
Use W-type PCBN where trigon geometry and abrasive-wear resistance suit grey, hard or interrupted cast-iron turning.
