Product Overview
The Kyocera 1/2 inch 5-Flute Carbide Endmill with 0.010R Corner Radius (MPN SGS38828) is a premium solid carbide rotary cutting tool engineered for high-performance CNC milling. Featuring five flutes and a precision-ground corner radius, this endmill balances material removal rate with exceptional surface finish, making it ideal for contouring, profiling, and finishing operations in alloy steels, stainless steels, and cast iron. The advanced TM-grade multi-layer coating minimizes built-up edge and crater wear, while the WF flute geometry improves chip evacuation and reduces cutting forces. Designed for modern machining centers, it delivers stable, repeatable performance even at elevated cutting speeds.

Grade Details - Key Grade Characteristics
The TM WF grade pairs a sub-micron cemented carbide substrate with a multi-layer TiAlN-based nano coating. This combination provides high hardness, excellent thermal stability, and superior adhesion resistance, enabling aggressive cutting parameters in steels and stainless steels while maintaining edge integrity.
| Property | Specification |
|---|---|
| Coating | Multi-layer TiAlN Nano Composite (TM series) |
| Hardness | 3,300 HV |
| Carbide Grain Size | Sub-micron, ∼0.5 µm |
| Transverse Rupture Strength | ∼4,200 N/mm² |
| Key Performance | High-speed finishing, wear resistance, low built-up edge |
Grade Comparison Matrix
| Property | TM WF (SGS38828) | PR General Purpose | CA Hardened Steel |
|---|---|---|---|
| Wear Resistance | ★★★★☆ | ★★★☆☆ | ★★★★★ |
| Heat Resistance | ★★★★★ | ★★★☆☆ | ★★★★☆ |
| Toughness / Chipping Resistance | ★★★★☆ | ★★★★☆ | ★★★☆☆ |
| Surface Finish | ★★★★★ | ★★★☆☆ | ★★★★☆ |
| Recommended Max Hardness | 48 HRC | 40 HRC | 65 HRC |
Chipbreaker Profile
The endmill employs a continuous helical flute design. The WF geometry incorporates variable helix angles and polished rake surfaces that act as a chip deflector, producing short, manageable chips and reducing harmonics during full-slot and profiling cuts.
- 5-flute continuous helical flute with variable pitch for chatter suppression
- Polished rake face and corner radius for smooth chip flow
- Optimized core thickness balances rigidity and chip pocket volume
- 0.010R corner radius improves edge strength and surface finish

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Face Milling / Shouldering | ★★★★★ | Excellent surface finish with low radial engagement |
| Contouring / Profiling | ★★★★★ | Corner radius protects edges and improves cusp height |
| Slotting (Axial Depth up to 1xD) | ★★★★☆ | Use reduced speeds/feeds for chip evacuation |
| Roughing / High MRR | ★★★☆☆ | 5-flute design supports moderate roughing loads |
| Semi-Finishing | ★★★★★ | Preferred operation for dimensional accuracy |
| High-Speed Machining | ★★★★☆ | Stable up to ~12,000 rpm for 1/2 in. diameter |
Recommended Cutting Conditions
Values are starting recommendations; adjust based on machine rigidity, coolant, and part setup.
| Workpiece Material | Cutting Speed Vc | Feed Rate fn | Coolant |
|---|---|---|---|
| Carbon Steel | 120-180 m/min | 0.08-0.14 mm/tooth | Emulsion / Air |
| Alloy Steel | 90-140 m/min | 0.07-0.12 mm/tooth | Emulsion |
| Stainless Steel | 70-110 m/min | 0.06-0.10 mm/tooth | Emulsion / Oil |
| Cast Iron | 100-160 m/min | 0.10-0.16 mm/tooth | Air / Dry |
| Hardened Steel (45 HRC) | 50-80 m/min | 0.04-0.08 mm/tooth | Minimum Quantity Lubrication |
Operating Guidelines
- Runout: Maintain total indicator reading below 0.01 mm at the tool point to prevent uneven wear and chatter.
- Peck Cycle: Not typically required for profiling; for deep slotting, use peck depth 1-1.5xD with full coolant flush.
- Coolant: Flood emulsion or air blast is recommended; avoid thermal shock with direct compressed air on hot carbide.
- Entry Angle: Use helical or ramp entry with angle ≤2°; avoid direct plunge unless using a center-cutting variant.
- Speed/Feed: Start at the lower end of the recommended range and increase feed in 10% steps while monitoring spindle load.
- Tool Life: Inspect corner radius and flank wear after each batch; retire tool when flank wear exceeds 0.15 mm or edge chipping appears.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Expansion Chuck | ★★★★★ | Best runout and dampening for finishing |
| Shrink Fit Chuck | ★★★★★ | High clamping force and concentricity |
| ER Collet Chuck (ER25/ER32) | ★★★★☆ | Ensure collet quality and correct torque |
| Milling Chuck | ★★★★☆ | Good gripping force for heavier cuts |
| Weldon Flat Holder | ★★★☆☆ | Use only if runout is verified below 0.02 mm |
