Product Overview
The Kyocera 1/2 ENDMILL 5FL 0.010R TM SGS38832 is a premium solid-carbide corner-radius end mill designed for high-performance CNC milling. With a 1/2 inch (12.7 mm) cutting diameter, five precision flutes, and a 0.010 inch corner radius, this tool balances material-removal rate with outstanding surface finish quality. The advanced TM multi-layer coating reduces friction and thermal load, enabling stable machining in carbon steels, alloy steels, stainless steels and cast irons. Optimised helix and core geometry improve chip evacuation, minimise chatter and extend tool life, making the SGS38832 an excellent choice for finish-profiling, semi-finishing, slotting and contouring in aerospace, automotive, die/mould and general production environments.

Grade Details - Key Grade Characteristics
The SGS38832 is built on an ultra-fine grain carbide substrate combined with a high-aluminium TiAlN-based TM coating. This pairing provides high hardness, excellent thermal stability and strong adhesion resistance, enabling reliable performance at elevated cutting temperatures while maintaining edge integrity.

| Hardness | 92 HRA |
| Grain Size | 0.5 µm (Ultra-Fine) |
| Rupture Strength | ≥ 3,800 MPa |
| Key Performance | High-speed finishing; superior wear and heat resistance; low built-up edge |
Grade Comparison Matrix
| Grade / Attribute | Wear Resistance | Heat Resistance | Toughness | Finish Quality | Productivity |
|---|---|---|---|---|---|
| Standard Carbide | ★★☆☆☆ | ★★☆☆☆ | ★★★☆☆ | ★★★☆☆ | ★★☆☆☆ |
| SGS38832 TM Grade | ★★★★☆ | ★★★★☆ | ★★★☆☆ | ★★★★★ | ★★★★☆ |
| Ultra-Micro Grain Carbide | ★★★★★ | ★★★★☆ | ★★☆☆☆ | ★★★★★ | ★★★★☆ |
Chipbreaker Profile
The five-flute geometry uses a variable-pitch, variable-helix arrangement that acts as a chip-management system, breaking chips into manageable lengths and disrupting harmonic chatter. The 0.010 inch corner radius adds strength to the cutting edges while preserving fine surface detail, and polished flutes aid evacuation in semi-finishing and finishing passes.
- Variable-index flute spacing suppresses regenerative chatter during high-speed profiling.
- 0.010 in corner radius reinforces the corner and improves edge durability.
- Polished rake faces reduce chip adhesion and improve surface finish.
- Five-flute core design balances chip pocket volume with tool rigidity.

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Roughing | ★★★☆☆ | Limited by corner radius and 5-flute chip space; light roughing only. |
| Semi-Finishing | ★★★★☆ | Excellent material removal with good surface quality. |
| Finishing | ★★★★★ | Corner radius produces high-quality blends and fine finishes. |
| Slotting | ★★★★☆ | Suitable for full-diameter slotting at moderate widths of cut. |
| Profiling / Contouring | ★★★★★ | Primary application; variable pitch reduces chatter on walls. |
| Pocketing | ★★★★☆ | Efficient corner radii and consistent wall finish. |
| High-Speed Machining | ★★★★☆ | Coating supports elevated surface speeds in stable set-ups. |
| Trochoidal Milling | ★★★☆☆ | Use reduced ae and high coolant flow in deep pockets. |
Recommended Cutting Conditions
| Material | Cutting Speed Vc | Feed Rate fn | Coolant |
|---|---|---|---|
| Carbon Steel | 120 - 180 m/min | 0.05 - 0.10 mm/tooth | Emulsion 6 - 8 % |
| Alloy Steel | 100 - 150 m/min | 0.04 - 0.08 mm/tooth | Emulsion 6 - 8 % |
| Stainless Steel | 80 - 120 m/min | 0.04 - 0.07 mm/tooth | Internal / External coolant |
| Cast Iron | 100 - 140 m/min | 0.05 - 0.09 mm/tooth | Air/oil mist or dry |
| Aluminium Alloys | 300 - 450 m/min | 0.10 - 0.18 mm/tooth | Air/oil or water-soluble |
| Hardened Steel (≤45 HRC) | 60 - 90 m/min | 0.03 - 0.06 mm/tooth | Oil mist or emulsion |
| Titanium Alloys | 40 - 60 m/min | 0.03 - 0.05 mm/tooth | High-pressure coolant |
Operating Guidelines
- Runout: Maintain TIR below 0.010 mm at the tool tip to maximise tool life and surface finish.
- Peck Cycle: Not normally required for end milling; use continuous tool-path strategies and avoid plunging without ramp or helix entry.
- Coolant: Apply adequate coolant flow directed at the cutting zone; prefer through-spindle coolant for deep pocketing and stainless/titanium alloys.
- Entry Angle: Use ramp or helix entry rather than direct plunging to protect the corner radius and prevent chipping.
- Speed/Feed: Start at the lower end of the recommended range and increase once chip formation and surface finish are verified stable.
- Tool Life: Monitor flank wear; regrind or replace when wear land exceeds 0.15 mm or when surface finish deteriorates.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER32/ER25 Collet Chuck | ★★★★★ | Best runout with high-precision collets. |
| Hydraulic Expansion Chuck | ★★★★★ | Excellent damping and balance for finishing. |
| Shrink Fit Holder | ★★★★★ | Optimal for high-speed machining. |
| Weldon Side-Lock Holder | ★★★☆☆ | Acceptable for moderate speeds; check runout. |
| Milling Chuck (Power Chuck) | ★★★★☆ | High clamping force and good runout. |
