Brazed PCBN Inserts for Hard Turning
ONMY supplies brazed PCBN inserts and CBN tipped inserts for hardened steel, cast iron, continuous cutting, interrupted cutting and precision finishing. Standard ISO shapes, multiple tip configurations and application-specific PCBN grades are available.
What Are Brazed PCBN Inserts?
A brazed PCBN insert uses a PCBN cutting tip joined to an indicizzabile insert body. The superhard PCBN material is positioned at the working edge, while the supporting insert body provides the required ISO shape, clamping geometry and dimensional stability.
Buyers may also search for these products as CBN tipped inserts. Tip count, edge length, insert shape and PCBN grade should be selected according to workpiece material, interruption level and cost per usable edge.
- Standard positive and negative ISO insert geometries
- Single-tip, multi-tip, entire-edge and chipbreaker structures
- PCBN grades for hard turning, cast iron and interrupted cutting
- Custom edge direction, radius and application review
Brazed PCBN Insert Tip and Edge Structures
Select the structure by usable cutting edges, edge engagement, chip control and application requirements.
1N
1-Tip Brazed PCBN Inserts
Single working PCBN tip for application-focused geometry and straightforward insert selection.
2N
2-Tip Brazed PCBN Inserts
Two usable PCBN tips can improve cost per cutting edge when the holder and operation allow indexing.
3N
3-Tip Brazed PCBN Inserts
Three-corner options are available on selected triangle and trigon insert families.
E
Entire-Edge PCBN Inserts
An extended PCBN edge supports wider edge engagement than a localized tip structure.
L
Long-Edge PCBN Inserts
Long-edge D-type options increase the available cutting-edge length for selected turning applications.
CB
Chipbreaker PCBN Inserts
Chipbreaker geometries are available in selected negative ISO families for improved chip management.
How Tip Structure Affects Cutting Engagement
Tip count and PCBN edge length mainly affect usable cutting edges, supported engagement and cost per edge. Final speed, feed and depth of cut still depend on the grade, geometry, workpiece and cutting continuity.
1-Tip PCBN Inserts
A single PCBN tip is a direct choice when the operation needs one defined cutting corner and simple orientation.
- Best fit: application-specific single-edge turning
- Selection focus: holder direction and edge access
- Cost direction: one usable PCBN tip
Multi-Tip PCBN Inserts
Multiple brazed tips can reduce cost per usable edge when the holder and component allow indexing to every corner.
- Best fit: repeat production and indexable use
- Selection focus: access to each cutting tip
- Cost direction: more usable edges per insert
Entire-Edge PCBN Inserts
An extended PCBN edge is selected when the cut needs more edge engagement than a localized corner tip can provide.
- Best fit: wider cutting contact or profile engagement
- Selection focus: supported edge length and stock allowance
- Check: insert body and holder rigidity
Long-Edge PCBN Inserts
Long-edge structures provide additional usable PCBN length for selected D-type turning and profiling operations.
- Best fit: longer edge contact and profile cuts
- Selection focus: cutting direction and engagement length
- Check: overhang, stability and depth of cut
Chipbreaker PCBN Inserts
Chipbreaker geometries are used where chip flow and chip control matter more than a flat cutting surface.
- Best fit: operations with chip-control requirements
- Selection focus: feed, depth of cut and chip formation
- Families: selected CNGM, DNGM, SNGM and WNGM
Chamfer and Edge-Hone Direction
Edge preparation influences cutting force, edge strength and resistance to chipping in continuous or interrupted cutting.
- Stable finish cut: prioritize controlled wear and finish
- Interrupted cut: prioritize stronger edge support
- Final choice: confirm with material and failure mode
Do not select speed, feed or depth of cut from tip count alone. Use the material-specific Hard Turning, Cast Iron or Turning Inserts pages for starting parameters.

Why Choose Brazed PCBN Inserts?
Brazed construction combines a targeted PCBN cutting edge with a broad range of indexable insert bodies and tip configurations.
Targeted PCBN Cutting Edge
PCBN material is placed at the working edge instead of across the complete insert body.
Broad ISO Shape Range
Positive and negative ISO bodies support multiple turning and profiling requirements.
Cost-per-Edge Options
1N, 2N and 3N structures allow buyers to compare usable cutting edges and order cost.
Application Matching
Grade, edge length and preparation can be selected around material and interruption level.
| Selection Factor | Brazed / Tipped PCBN | Full-Face or Solid PCBN Structure |
|---|---|---|
| PCBN location | Localized tip or extended brazed edge | Larger PCBN cutting body |
| Common options | 1N, 2N, 3N, entire edge and chipbreaker | Depends on full-face or solid product family |
| ISO shape flexibility | Broad tipped ISO insert range | More dependent on available solid/full-face geometry |
| Typical selection reason | Targeted cutting edge, structure choice and application flexibility | More PCBN material or additional usable cutting positions |
Brazing and Edge Quality for PCBN Inserts
Reliable performance depends on accurate tip positioning, a consistent joining area, correct edge preparation and dimensional control. Confirm the inspection method and documentation available for your order before publishing additional manufacturing claims.
Brazed PCBN Inserts Price and Manufacturer Support
Price depends on the ISO code, PCBN grade, number of tips, edge structure, radius, order quantity and customization requirements.
Brazed PCBN Inserts: Common Questions
What are brazed PCBN inserts?
Brazed PCBN inserts use a PCBN cutting tip joined to an indexable insert body. The PCBN material forms the working cutting edge, while the insert body provides the required ISO shape and clamping geometry.
Are brazed PCBN inserts the same as CBN tipped inserts?
In commercial searches, buyers often use “brazed PCBN inserts” and “CBN tipped inserts” for the same general product structure: a localized PCBN cutting tip joined to an insert body.
What is the difference between 1-tip, 2-tip and 3-tip PCBN inserts?
The number describes how many usable PCBN cutting tips are available on the insert. The correct option depends on insert shape, holder orientation, indexing access and desired cost per usable edge.
Which brazed PCBN grade is suitable for hard turning?
The selection depends on workpiece hardness, cutting speed and interruption. Lower-CBN grades are commonly used for stable finish hard turning, while tougher grades are selected as interruption and impact increase.
Can brazed PCBN inserts machine cast iron?
Yes. High-CBN grades can be used for grey cast iron, hard cast iron, fine boring and valve-seat applications. The correct grade and geometry should be confirmed from the material and cutting condition.
What is an entire-edge PCBN insert?
An entire-edge insert uses an extended PCBN cutting edge rather than a small localized tip. It is selected when the application needs wider edge engagement or a longer PCBN edge.
How can I get brazed PCBN inserts price?
