1. Product Overview
The Kyocera 1/2 ENDMILL 5FL 0.010R TM WF SGS38834 is a high-performance solid carbide end mill engineered in Japan for demanding CNC milling operations. Featuring a 1/2 inch cutting diameter, five precision-ground flutes, and a tight 0.010 inch corner radius, this tool is purpose-built for finishing and semi-finishing of ferrous and non-ferrous workpiece materials. The 5-flute geometry increases core strength and improves chip evacuation compared with 4-flute designs, while the corner radius enhances edge durability and surface finish. A specialized TM WF carbide grade substrate and advanced wear-resistant coating deliver extended tool life, consistent dimensional accuracy, and reliable performance in high-speed machining centers, mold-and-die shops, aerospace component manufacturing, and general production environments.
2. ISO Designation Breakdown
| ISO Designation | SGS38834 (manufacturer designation; ISO 513 groups P/M/K applicable per material) |
| Tool Type | Solid Carbide End Mill |
| Size | 1/2 in dia x 5 flutes x 0.010 in corner radius |
| Grade Class | TM WF Micro-grain Carbide |
| Manufacturer Code | Kyocera SGS38834 |
3. Engineering Dimensions & Geometry
| Parameter | Specification | Tolerance |
|---|---|---|
| Cutting Diameter (D1) | 12.70 mm (1/2 in) | h6 / +0.000/-0.011 mm |
| Corner Radius (r) | 0.254 mm (0.010 in) | ±0.013 mm |
| Flute Length (L1) | 31.75 mm (1.25 in) | ±0.25 mm |
| Overall Length (L) | 76.2 mm (3.0 in) | ±0.50 mm |
| Shank Diameter (D2) | 12.70 mm (1/2 in) | h6 |

4. Grade Details - Key Grade Characteristics
The TM WF grade is a premium sub-micron grain carbide engineered for high-speed finishing and light-to-medium machining duties. It combines high hardness with sufficient toughness to resist chipping on corner radii, while a multilayer PVD coating reduces crater wear and built-up edge when cutting steels, stainless steels, and cast irons.
| Coating | Hardness (HRA) | Grain Size | Rupture Strength | Key Performance |
|---|---|---|---|---|
| AlTiN-based PVD multi-layer | 92.0 | 0.5 µm (sub-micron) | ≥ 4,000 MPa | High wear resistance, thermal stability, fine finishes |
5. Grade Comparison Matrix
| Grade | Wear Resistance | Heat Resistance | Toughness | Finish Quality |
|---|---|---|---|---|
| TM WF (SGS38834) | ★★★★☆ | ★★★★☆ | ★★★☆☆ | ★★★★★ |
| CA025P | ★★★★☆ | ★★★☆☆ | ★★★★☆ | ★★★☆☆ |
| PR1535 | ★★★☆☆ | ★★★★★ | ★★★☆☆ | ★★★★☆ |
6. Chipbreaker Profile
Although end mills do not use indexable chipbreakers, the SGS38834 incorporates a precision edge preparation and flute form that acts as a chip management system. The geometry is optimized to curl chips away from the workpiece, minimize cutting forces, and protect the corner radius from micro-chipping.
- 0.010 in corner radius edge preparation improves strength and surface finish
- Variable helix and pitch geometry break harmonic vibration and reduce chatter
- Polished flute surfaces lower friction and aid chip evacuation
- Positive rake face reduces cutting forces and heat generation
- Center-cutting capability permits axial ramping and plunge entry
7. Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended |
|---|---|---|
| Carbon & Alloy Steels | Good | ✓ Yes |
| Stainless Steels (300/400 series) | Moderate | ✓ Yes |
| Cast Iron | Good | ✓ Yes |
| Aluminum Alloys | Excellent | ✓ Yes |
| Titanium Alloys | Low | △ With Caution |
| Hardened Steels (45-55 HRC) | Low-Moderate | ○ Limited |
| High-Temp / Nickel Alloys | Low | △ With Caution |
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Roughing | ★★★☆☆ | Light-to-medium roughing; full slotting depth limited by 5-flute core |
| Semi-Finishing | ★★★★☆ | Excellent material removal and transition to finishing passes |
| Finishing | ★★★★★ | Primary application; 0.010R radius yields superior surface finish |
| Slotting | ★★★☆☆ | Center cutting; reduce axial depth to 1xD for optimal chip evacuation |
| Profiling / Side Milling | ★★★★★ | High radial engagement at moderate axial depths |
| Plunge Milling | ★★★☆☆ | Possible with ramp/plunge strategy; use peck cycle |
| High-Speed Machining | ★★★★☆ | Stable in rigid setups and balanced holders |
9. Recommended Cutting Conditions
| Material | Cutting Speed Vc (m/min) | Feed Rate fz (mm/tooth) | Coolant |
|---|---|---|---|
| Carbon Steel (1045) | 180-240 | 0.06-0.10 | Emulsion / Air blast |
| Stainless Steel (304) | 80-130 | 0.05-0.08 | High-pressure coolant recommended |
| Cast Iron | 120-180 | 0.07-0.12 | Compressed air / mist |
| Aluminum (6061) | 250-400 | 0.08-0.15 | Flood or air blast |
| Titanium (Ti-6Al-4V) | 40-70 | 0.04-0.07 | High-volume flood coolant |
| Hardened Steel (50 HRC) | 60-100 | 0.03-0.06 | Minimum quantity or flood |
10. Operating Guidelines
- Runout: Maintain total indicator runout below 0.010 mm (0.0004 in) at the tool point to preserve corner radius and surface finish.
- Peck Cycle: When drilling/plunging, use peck depths of 0.5-1.0xD with full retract to clear chips and prevent packing in 5-flute geometry.
- Coolant: Use flood, high-pressure, or air blast depending on material; avoid thermal shock by keeping coolant continuous once started.
- Entry Angle: Prefer helical or ramp entry at 1-3°; avoid direct 90° plunge unless using dedicated plunge strategy.
- Speed/Feed: Start at the lower end of the recommended range and increase incrementally while monitoring spindle load and part temperature.
- Tool Life: Inspect corner radius and flank wear after each batch; re-sharpen or replace when flank wear exceeds 0.15 mm or finish deteriorates.
11. Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER32/ER40 Collet Chuck | ★★★★☆ | Suitable for general finishing; verify collet condition |
| Hydraulic Expansion Chuck | ★★★★★ | Best runout and damping for finishing |
| Milling Chuck (Power Chuck) | ★★★★☆ | Good grip and rigidity for semi-finishing |
| Shrink Fit Holder | ★★★★★ | Optimal for high-speed machining and balance |
| Weldon Flat / Side-Lock | ★★★☆☆ | Adequate for lower-speed roughing; check balance |
