How to Select a Chipbreaker
The chipbreaker influences chip formation, cutting forces, edge strength, surface quality and machining stability.
Recommended Selection Sequence
1. Confirm the machining operation.
2. Confirm the workpiece material and hardness.
3. Determine the required depth of cut and feed range.
4. Evaluate machine and workpiece stability.
5. Select the grade and chipbreaker as one complete combination.
| Application | Typical Requirement | Operation / Condition | Selection Direction | Information Required |
| Finishing | Good surface and low cutting force | Stable / continuous | Sharp edge, low feed and small depth of cut | Material, finish target, allowance |
| Medium Machining | Balanced chip control and edge strength | General conditions | General-purpose chipbreaker | Material, feed, depth of cut |
| Roughing | Strong edge and high material removal | Interrupted or unstable | Reinforced edge and larger chip space | Allowance, interruption, machine power |
| Grooving & Parting | Chip evacuation and width control | External, internal or face operation | Select by groove width, depth and holder | Groove width/depth, holder model |
| Threading | Correct profile and stable chip formation | Internal or external thread | Select by profile, pitch and infeed method | Thread type, pitch, direction, holder |
JetEdge Chipbreaker Naming
JetEdge chipbreaker codes are the official product designations used in product pages, quotations, packaging and order documents.
Common market reference terms may be included in product descriptions or search keywords only to help customers identify the requested application. These terms do not indicate affiliation with another brand and do not guarantee identical geometry or performance.
For example:
• MGM is the official JetEdge chipbreaker code; “M2-type” may be used only as a secondary industry reference term.
• MRA is the official JetEdge chipbreaker code; “DL-type” may be used only as a secondary industry reference term.
Final geometry and application suitability must be confirmed according to the actual insert drawing, dimensions and cutting conditions.
