Recommended for heavy interrupted cuts
Excellent toughness and stable machining
Ideal for hardened materials of HRC 55 or higher
Features
- Exceptional toughness due to a special TiN binder blended with the CBN
- Chipping resistance achieves stable machining through heavy interruptions
Tooling application
Heavy interrupted machining of hardened materials of HRC55 or above
Cutting conditions
Grade | Material | Operation type | Machining | Cutting speed (m/min) | Feed (mm/rev) | DOC (mm) | DRY | WET |
G41 | Hardened material (HRC 55 or above) | Turning Heavy interrupted machining | Finishing | 30 – 150 | ~ 0.1 | 0.1 – 1.0 | ⚫ | ⚪ |
Edge preparations
Performance comparison by edge preparation
- As the edge preparation increases the tool pressure on the insert increases.
- [ Cutting conditions ]
- SCM415(HRC63-65) vc=200m/min f=0.1mm/rev ap=0.2mm, DRY
- [ Insert ] TNGA160408
- There is a direct correlation between an increase in the edge preparation and improvement of insert fracture resistance.

Case study
| Interrupted ID boring of automotive parts | ||
|---|---|---|
|  | |
| ||
| ||
| ||
| ||
| G41 | 2,300 pcs / corner | |
| Competitor’s CBN | 1,500 pcs / corner | |
G41 achieved longer tool life through the heavy interruptions without chipping
| Interrupted OD turning gear part coupling | ||
|---|---|---|
|  | |
| ||
| ||
| ||
| ||
| G41 | 400 pcs / corner | |
| Competitor’s CBN | 100 pcs / corner | |
Competitor’s CBN had edge damage due to interruptions. G41’s excellent toughness achieved 4 times longer tool life.
