Triangle Geometry

Select T-Type Geometry by Clearance and Tip Use

Negative TNGA and positive triangular families such as TCGW and TPGW serve different holder and cutting-force requirements. Choose by clearance, access, usable tip count and PCBN edge structure.

Negative TNGA

TNGA / TNMA is the main multi-tip negative T-type platform in the ONMY catalog.

  • 1N and 3N tip-count options
  • TNGA-E / TNMA-E entire-edge structure
  • 1604 and 2204 catalog sizes
  • Stable negative body with multiple PCBN tip options

Positive Triangle Families

TCGW / TCGT and TPGW / TPGT provide positive triangular options for reduced cutting force and access-sensitive turning.

  • TCGW / TCGT: 7° family direction
  • TPGW / TPGT: 11° family direction
  • 1102 and 16T3 catalog sizes
  • Entire-edge versions available in TCGW-E and TPGW-E families
Full-face distinction: TBGA-F / TBMA-F, TBGN-F / TBMN-F and TBGW-F / TBMW-F are cataloged as 5° full-face triangle PCBN families. They are included here because they are T-type products, but they should not be described as conventional corner-tipped brazed inserts.

The table reproduces the T-type dimensional symbols from the ONMY product catalog. Grade availability is not shown here because it varies by exact size and PCBN structure.

Tip, Edge & Face Structures

Choose the T-Type PCBN Structure

Triangle PCBN inserts in the catalog span localized tips, multi-tip negative structures, entire-edge positive and negative versions, and selected full-face families.

1N

1-Tip

Single localized PCBN cutting tip across negative TNGA and positive TCGW / TPGW / TCGT / TPGT families.

3N

3-Tip TNGA

Three usable PCBN tips are available in selected TNGA / TNMA sizes for better cost per usable tip.

E

Entire Edge

TNGA-E, TCGW-E and TPGW-E families provide extended PCBN edge engagement.

F

Full Face

TBGA-F, TBGN-F and TBGW-F are the cataloged 5° full-face triangle PCBN families.

PCBN Grade Direction

Match the Grade to Material and Cutting Condition

T-type inserts are available across several PCBN grade directions. Choose the exact grade after the family, size, workpiece material, hardness and cutting continuity are known.

45

OBN45

Wear-focused direction for continuous to moderately interrupted hard turning and fine finishing.

50

O2C50

Abrasion-resistant direction for continuous to lightly interrupted hard machining.

85

OBW85

High-CBN direction for abrasive workpieces, selected cast-iron applications and demanding interruption.

APP

Confirm by Code

Exact grade availability varies by T-type size and PCBN structure. Confirm the final combination before ordering.

Application Direction

Where T-Type PCBN Inserts Fit

Triangular PCBN product pages commonly target hardened-steel and cast-iron turning. Use the triangle body for the required approach and access, then select grade and edge structure by the actual cut.

Hard Turning

Use TNGA or positive T-type families for hardened-steel turning and finishing, then select the grade by hardness and interruption.

CBN Inserts for Hard Turning →

Cast Iron Machining

Positive TCGW / TPGW and other triangle families can be selected for cast-iron turning where component access and cutting-force direction suit the geometry.

CBN Inserts for Cast Iron →

CBN Tipped Structures

Compare 1N, 3N and entire-edge tipped structures across the broader CBN insert range.
