Product Overview
The Kyocera SGS31217 is a precision-engineered solid carbide 4FL end mill set featuring the TA – Uncoated Micro-Grain Carbide grade. This comprehensive set includes multiple sizes designed for Ball Nose applications, delivering exceptional surface finish, dimensional accuracy, and extended tool life on CNC machining centers and 5-axis milling machines. The None (Uncoated) ensures stable performance across high-speed machining operations.
Product Code Designation Breakdown

| Surface Finish Quality | ★★★★★ | ★★★★★ | Mirror-finish die/mold work |
| Price Point | Premium | Standard | Cost-sensitive aluminum work |
Flute Geometry & Chip Management Profile
Each end mill in the SGS31217 set features an optimized flute geometry specifically engineered for consistent chip evacuation and surface finish across all included sizes:
- Helix Angle: 35° — provides smooth cutting action and gradual chip evacuation, minimizing chatter in deep-pocket machining.
- Core Diameter Ratio: 65% of tool diameter — ensures maximum rigidity for reduced deflection in long-overhang operations.
- Flute Width: Optimized for 4-flute balance between chip space and tool core strength.
- Edge Preparation: Honing (0.02–0.03 mm) on primary cutting edges to prevent micro-chipping during high-speed engagement.
- Surface Finish: Mirror-polished flutes (Ra 0.1 μm) reduce friction and built-up edge formation.
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended Operation | Expected Tool Life |
|---|---|---|---|
| Carbon Steel (C45, 1045) | ★★★★★ | Profiling, finishing, contouring | Excellent |
| Alloy Steel (4140, 4340) | ★★★★☆ | Semi-finishing, 3D machining | Very Good |
| Stainless Steel (304, 316) | ★★★☆☆ | Light finishing, contouring | Good |
| Cast Iron (GG25, GGG50) | ★★★★★ | Profiling, mold finishing | Excellent |
| Hardened Steel (HRC 45–55) | ★★★☆☆ | Hard milling, die finishing | Moderate |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Profiling / Contouring | ★★★★★ | Primary application; excellent surface finish across all set sizes |
| Slotting | ★★★☆☆ | Select appropriate size for slot width; not ideal for full slotting with ball nose |
| Plunging | ★★★☆☆ | Use ramp entry; avoid direct plunging with square-end tools |
| 3D Finishing | ★★★★★ | Optimal for complex freeform surfaces with ball nose variants |
| High-Feed Roughing | ★★☆☆☆ | Not recommended; use dedicated roughing tools |
Recommended Cutting Conditions
Parameters vary by tool size within the set. Refer to the individual size specifications for precise cutting data. General guidelines for Grade TA 4FL end mills are provided below.
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Ap Max (% of D) | Coolant |
|---|---|---|---|---|
| Carbon Steel | 80–120 | 0.03–0.06 | 50% | External / MQL |
| Stainless Steel | 60–90 | 0.02–0.04 | 35% | External / Flood |
| Aluminum Alloy | 150–300 | 0.05–0.10 | 75% | Air Blast / MQL |
| Cast Iron | 100–140 | 0.04–0.08 | 60% | Dry / Compressed Air |
Operating Guidelines
- Runout Check: Maintain TIR ≤ 0.01 mm at the tool tip. Excessive runout reduces tool life by 30–50%.
- Engagement Strategy: Use arc-in / arc-out toolpaths for entry. Avoid 90° direct plunging with square-end tools.
- Chip Evacuation: Ensure adequate coolant flow or air blast to prevent chip recutting, especially in deep pockets.
- Speed Ramp: Ramp spindle speed over 3–5 seconds to avoid thermal shock to the carbide substrate.
- Tool Inspection: Inspect cutting edges under 10× magnification after every 30 minutes of cutting time.
- Depth of Cut: For finishing, keep axial depth (Ap) at 0.5×D or less. For semi-finishing, Ap up to 1.0×D is acceptable.
- Corner Wear Limit: Retire tool when flank wear exceeds 0.15 mm or when surface finish degrades below Ra 0.8 μm.
