Chipbreaker Profile
The 0.0253FLBN utilizes a Semi-Finishing (SF) chipbreaker geometry. This profile is engineered to produce tightly curled chips that evacuate smoothly from the cutting zone, reducing built-up edge and minimizing the risk of chip recutting. The optimized rake face minimizes cutting forces while maintaining edge strength, making it ideal for both roughing and finishing passes in continuous and interrupted cuts.
- Positive rake angle for reduced cutting forces and heat generation
- Polished flute surface (Ra 0.2 μm) for superior chip flow
- Variable pitch design to suppress chatter and harmonics
- Reinforced cutting edge corner for improved impact resistance
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended Use |
| Carbon Steel (≤ 45 HRC) | ★★★★★ Excellent | Primary application — high-speed roughing & finishing |
| Alloy Steel (≤ 50 HRC) | ★★★★☆ Very Good | Ideal for die & mold, automotive components |
| Stainless Steel (304, 316) | ★★★★☆ Very Good | Excellent chip control and surface finish |
| Tool Steel (≤ 55 HRC) | ★★★☆☆ Good | Suitable for hardened die & mold finishing |
| Cast Iron (Gray / Ductile) | ★★★★☆ Very Good | Good for general engineering applications |
Application Map by Operation
| Operation Type | Suitability | Notes |
| 3D Contouring / Profiling | ★★★★★ Excellent | Ball-nose geometry optimized for complex surfaces |
| Slotting (Full Width) | ★★★☆☆ Good | Use reduced DOC; ensure adequate chip evacuation |
| Pocketing / Cavity Milling | ★★★★☆ Very Good | Excellent for internal corners and fillets |
| High-Speed Finishing | ★★★★★ Excellent | Achieves Ra 0.2 – 0.4 μm surface finish |
| Trochoidal Milling | ★★★★☆ Very Good | High-feed capability with stable chip formation |
Recommended Cutting Conditions
Parameters below are starting recommendations for carbon steel (≤ 35 HRC). Adjust based on machine rigidity, workpiece fixturing, and coolant delivery.
| Parameter | Roughing | Semi-Finish | Finishing |
| Spindle Speed (SFM) | 10,000 – 30,000 | 12,000 – 36,000 | 15,000 – 45,000 |
| Feed per Tooth (fz) | 0.005 – 0.015 mm/t | 0.003 – 0.01 mm/t | 0.002 – 0.006 mm/t |
| Axial DOC (ap) | 0.2 – 1.0x D1 | 0.1 – 0.5x D1 | 0.05 – 0.2x D1 |
| Radial WOC (ae) | 0.6 – 0.8x D1 | 0.3 – 0.5x D1 | 0.05 – 0.15x D1 |
| Coolant | External / Through-spindle | Through-spindle preferred | Air blast / MQL acceptable |
Operating Guidelines
- Run-out Check: Verify tool run-out is ≤ 5 μm at the tool tip before operation. Excessive run-out accelerates edge chipping.
- Pre-warming: For high-precision applications, perform a 5-minute warm-up run at 50% rated speed to stabilize thermal expansion.
- Coolant Quality: Use water-miscible coolant at 8–10% concentration. Avoid chlorine-based additives that may corrode the coating.
- Tool Life Monitoring: Monitor flank wear (VB). Recommended regrind or replacement at VB = 0.15 mm for finishing, VB = 0.25 mm for roughing.
- Storage: Store in original packaging away from humidity. Coated tools should not contact uncoated carbide to prevent coating damage.
- Recutting Prevention: Ensure adequate coolant pressure (≥ 70 bar for through-spindle) to flush chips from the cutting zone.
