1. Product Overview
The Kyocera 1/2 ENDMILL 5FL 0.010R TM WF SGS38840 is a premium solid carbide endmill engineered for high-performance CNC milling operations. Featuring a 1/2 inch diameter, five-flute configuration, and a micro 0.010 inch corner radius, this cutting tool delivers exceptional surface finish, dimensional accuracy, and extended tool life in demanding finishing and semi-finishing applications. The TM-series coating combined with the WF chipbreaker geometry provides reduced cutting forces, improved chip evacuation, and superior heat resistance, making it ideal for aerospace, automotive, die/mold, and general precision manufacturing environments where process reliability and repeatability are critical.
2. ISO Designation Breakdown
| ISO Designation | 1/2 ENDMILL 5FL 0.010R TM WF |
| Tool Type | Solid Carbide Endmill |
| Size | 1/2" (12.70 mm) |
| Grade Class | TM Coated Carbide |
| Manufacturer Code | SGS38840 |
3. Engineering Dimensions & Geometry
| Parameter | Specification | Tolerance |
|---|---|---|
| Cutting Diameter (D1) | 1/2" (12.70 mm) | h6 |
| Corner Radius | 0.010" (0.254 mm) | ±0.002" |
| Number of Flutes | 5 | — |
| Shank Diameter | 1/2" (12.70 mm) | h6 |

| Helix Angle | Variable / Standard | ±2° |
4. Grade Details - Key Grade Characteristics
The TM grade combines an ultra-fine grain carbide substrate with an advanced PVD multi-layer coating engineered for high-speed finishing and semi-finishing of steels, stainless steels, and high-temperature alloys. It offers exceptional hardness, thermal stability, and oxidation resistance while maintaining adequate toughness for interrupted cuts and unfavorable entry conditions.
| Coating | PVD TM Multi-Layer (TiAlN-based) |
| Hardness | ~1,920 HV |
| Grain Size | Ultra-Fine (Sub-micron) |
| Rupture Strength | High |
| Key Performance | Excellent wear resistance, high heat resistance, good edge stability, superior surface finish |
5. Grade Comparison Matrix
| Property | TM | CA | PR |
|---|---|---|---|
| Wear Resistance | ★★★★★ | ★★★★☆ | ★★★☆☆ |
| Heat Resistance | ★★★★★ | ★★★★☆ | ★★★★☆ |
| Toughness | ★★★★☆ | ★★★★☆ | ★★★★★ |
| Surface Finish | ★★★★★ | ★★★★☆ | ★★★☆☆ |
| Versatility | ★★★★★ | ★★★★☆ | ★★★★☆ |
6. Chipbreaker Profile
The WF chipbreaker geometry is specifically designed for finishing operations where chip control and surface quality are paramount. Its finely ground rake face and smooth edge preparation reduce burr formation and minimize built-up edge when machining sticky or work-hardening materials.
- Low cutting force profile ideal for thin-wall and finishing applications
- Optimized rake angle for excellent chip thinning and evacuation
- Polished flutes reduce material adhesion and built-up edge
- Stable edge preparation provides consistent tool life at high cutting speeds
7. Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended |
|---|---|---|
| Carbon / Alloy Steels | Good | ✓ Yes |
| Stainless Steels | Moderate | ✓ Yes |
| Cast Irons | Good | ✓ Yes |
| Titanium Alloys | Difficult | △ With Caution |
| Nickel-Based Superalloys | Difficult | △ With Caution |
| Hardened Steels (>45 HRC) | Low | ○ Limited |
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Side Milling / Finishing | ★★★★★ | Primary application; superior surface finish |
| Slotting | ★★★☆☆ | Use light radial engagement due to 5-flute geometry |
| Profiling | ★★★★★ | Excellent dimensional accuracy and finish |
| Pocketing | ★★★★☆ | Recommended with trochoidal or adaptive toolpaths |
| High-Speed Machining | ★★★★★ | Optimized for elevated surface speeds and feeds |
9. Recommended Cutting Conditions
| Material | Cutting Speed Vc | Feed Rate fn | Coolant |
|---|---|---|---|
| Mild / Carbon Steel | 120–180 m/min | 0.05–0.10 mm/tooth | Emulsion / Air |
| Alloy Steel | 90–150 m/min | 0.05–0.09 mm/tooth | Emulsion |
| Stainless Steel | 70–120 m/min | 0.04–0.08 mm/tooth | High-Pressure |
| Cast Iron | 100–160 m/min | 0.06–0.11 mm/tooth | Air / MQL |
| Titanium Alloy | 40–70 m/min | 0.03–0.06 mm/tooth | High-Pressure |
10. Operating Guidelines
- Runout: Maintain total indicator runout below 0.010 mm to avoid uneven wear and premature chipping.
- Peck Cycle: Not required for standard side milling; use helical entry or ramping for pocketing applications.
- Coolant: Apply consistent coolant flow directed at the cutting zone; through-tool coolant is recommended for deep pockets.
- Entry Angle: Use ramp or helical entries with angles below 2° to protect the corner radius.
- Speed/Feed: Start at the lower end of recommended ranges for unfamiliar materials and increase gradually based on tool life observations.
- Tool Life: Inspect flutes after each operation for coating wear or edge chipping; replace when surface finish degrades or cutting forces increase.
11. Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best damping and runout control |
| Shrink Fit Chuck | ★★★★★ | Excellent rigidity for high-speed machining |
| Collet Chuck (ER32/ER40) | ★★★★☆ | Use precision collets and verify runout |
| Milling Chuck | ★★★★★ | High clamping force and stability |
| End Mill Holder | ★★★☆☆ | Acceptable for conventional speeds only |
