CBN Insert Codes, Shapes and Sizes
Search common CBN and PCBN insert codes, compare C, D, S, T, V and W shapes, and review positive and negative ISO families. Use the full code, radius, tip structure and edge direction when requesting a quotation or cross-reference.
How to Read a CBN Insert Code
A complete insert code describes the insert body and nominal dimensions. The PCBN tip structure, grade and edge direction may be added separately in the catalog or quotation.
Browse CBN Insert Codes by Shape
Use the shape family to narrow the holder compatibility and machining access before checking the exact size.
C-Type 80° Rhombic
Stable general turning and facing geometry.
D-Type 55° Rhombic
Profiling, shoulder access and long-edge options.
S-Type Square
Rigid square geometry for stable hard machining.
T-Type Triangle
Multiple-corner general turning geometry.
V-Type 35° Rhombic
Fine profiling and access to complex contours.
W-Type Trigon
Multi-corner geometry for economical turning.

The complete catalog contains additional sizes, radii and positive/negative families. Confirm the final dimension and available PCBN grade from the exact insert matrix.
PCBN Tip and Edge Structure Codes
The ISO body code does not always describe the complete PCBN cutting structure. Include the additional structure in your enquiry.
One Brazed PCBN Tip
One usable PCBN corner with a defined cutting direction.
Two Brazed PCBN Tips
Two usable PCBN cutting corners on selected insert families.
Three Brazed PCBN Tips
Three-corner structures on selected triangle and trigon families.
Entire Edge
Extended PCBN cutting edge for wider engagement than a localized tip.
Long Edge
Long-edge D-type structures for selected profiling and turning cuts.
Right or Left Edge
Identifies cutting-edge direction and corresponding holder orientation.
How to Confirm a CBN Insert Code
Copy the Full Code
Record every letter, number and suffix from the current insert or packaging.
Confirm Dimensions
Check inscribed circle, thickness, hole style and nose radius against the drawing.
Confirm PCBN Structure
Specify 1N, 2N, 3N, entire edge, long edge, chipbreaker and ER/EL direction.
Match Grade and Application
Provide the workpiece, hardness, cutting continuity and current grade.
Information Needed to Match an Insert Code
A similar-looking insert may have a different clearance, tolerance, hole, radius or edge direction. Send the complete specification before testing an alternative.
CBN Insert Codes and Sizes: Common Questions
What does CNGA120408 mean?
CNGA identifies the insert shape, clearance, tolerance and construction. The numeric groups identify the nominal size, thickness and nose radius. Additional PCBN tip and edge information may be specified separately.
What is the difference between CNGA and CCGW?
CNGA is a negative-clearance C-type insert family, while CCGW is a positive-clearance C-type family. They require different holder and cutting-condition considerations.
What do 1N, 2N and 3N mean?
They identify the number of usable brazed PCBN tips on the insert: one, two or three tips.
What do ER and EL mean?
ER and EL identify right- and left-edge orientation. The correct direction must match the holder and feed direction.
Can ONMY supply a CBN insert code that is not shown?
Send the complete code, drawing or sample. Availability should be confirmed from the actual dimensions, PCBN structure and grade requirement.
Can ONMY cross-reference Sandvik, Sumitomo or Mitsubishi codes?
Yes, send the original brand, complete part number, grade and application. A proposed alternative should be verified through machining tests.
Is every PCBN grade available in every insert size?
No. Grade availability varies by shape, size, radius and tip structure. Confirm the exact matrix before ordering.
