1. Product Overview
The Kyocera 197 0300 050 06 Solid Carbide Endmill (MPN: CEM01531) is a precision-engineered cutting tool designed for demanding CNC milling operations. Manufactured in Japan using Kyocera's proprietary Micro-grain carbide substrate and finished with the advanced MEGACOAT PVD coating, this endmill delivers exceptional wear resistance, thermal stability, and cutting-edge integrity.
With a cutting diameter of 3.0 mm and 6 flutes, this tool is optimized for Precision finishing and light roughing. The 38° helix angle ensures smooth chip evacuation and reduced cutting forces, making it ideal for high-efficiency machining across a broad spectrum of workpiece materials.

6. Chipbreaker Profile
The 197 series features an optimized chipbreaker geometry designed for efficient chip formation and evacuation across varied cutting parameters.
- Rake Angle: Positive 8°–12° (varies by flute) for reduced cutting forces and improved surface finish
- Clearance Angle: 10°–14° per flank for minimal flank wear and stable cutting edges
- Chip Pocket Depth: Optimized for 6-flute configuration to prevent chip recutting
- Gash Design: Wide gash angle for superior chip flow, especially in slotting operations
- Margin Width: Narrow margin for reduced friction and heat generation
- Edge Preparation: Micro-honed T-land (0.02–0.05 mm) for edge strength without sacrificing sharpness
7. Recommended Applications & Workpiece Materials

8. Application Map by Operation
| Operation Type | Suitability | Max Depth (ap) | Max Width (ae) | Notes |
|---|---|---|---|---|
| Slotting | ★★★★★ | 1.0 × Dc | 1.0 × Dc | Full-width engagement; use climb milling |
| Shouldering | ★★★★★ | 1.5 × Dc | 0.6 × Dc | Excellent wall finish; ideal for 90° shoulders |
| Profiling | ★★★★★ | 1.0 × Dc | 0.2 × Dc | Smooth contouring with minimal scallop |
| Plunge Milling | ★★★☆☆ | 0.5 × Dc | — | Center-cutting capable; reduce feed by 30% |
| Ramping | ★★★★☆ | 1.0 × Dc | 0.3 × Dc | Max ramp angle 3°–5° for optimal results |
| Helical Interpolation | ★★★★☆ | 1.0 × Dc | 0.1 × Dc | Excellent for large-diameter hole making |
9. Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Depth of Cut ap (mm) | Width of Cut ae (mm) |
|---|---|---|---|---|
| Carbon Steel (< 250 HB) | 97–137 | 0.05–0.12 | 3.0 | 1.8 |
| Alloy Steel (250–350 HB) | 117–147 | 0.04–0.10 | 2.4 | 1.4 |
| Stainless Steel | 62–92 | 0.03–0.08 | 1.8 | 1.1 |
| Gray Cast Iron | 137–187 | 0.06–0.15 | 3.0 | 1.8 |
| Titanium Alloy | 30–60 | 0.03–0.06 | 1.5 | 0.9 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant type, and desired surface finish. For finishing operations, reduce ap and ae by 50% and increase Vc by 20%.
10. Operating Guidelines
- Coolant: Flood coolant or high-pressure through-spindle coolant (70+ bar) recommended for stainless steel and titanium. Compressed air or minimal quantity lubrication (MQL) acceptable for carbon steel and cast iron.
- Runout: Maintain total indicated runout (TIR) < 0.01 mm at the tool tip for optimal tool life and surface finish.
- Clamping: Use precision collet chucks or hydraulic chucks. Avoid standard drill chucks for endmills.
- Entry Strategy: Use ramp or helical entry into solid material. Avoid direct plunge except for center-cutting tools at reduced feed.
- Chip Evacuation: Ensure adequate chip evacuation to prevent recutting, which causes premature wear and poor surface finish.
- Tool Life Monitoring: Monitor flank wear (VB). Recommended regrind or replacement when VB exceeds 0.2 mm for roughing or 0.1 mm for finishing.
- Storage: Store in original packaging away from moisture and corrosive atmospheres. Protect cutting edges from contact with other tools.
