Product Overview
The Kyocera 1/2 ENDMILL 5FL 0.010R TA SGS38833 is a high-performance solid carbide corner-radius end mill engineered for precision CNC milling operations. With a 1/2-inch (12.70 mm) cutting diameter, five-flute configuration, and a tight 0.010-inch (0.254 mm) corner radius, this cutter is designed to deliver exceptional surface finish, tight dimensional accuracy, and extended tool life on demanding workpiece materials. The advanced TA carbide grade, combined with a modern PVD wear-resistant coating and optimized flute geometry, reduces cutting forces, improves chip evacuation, and supports stable high-speed machining. It is the ideal choice for aerospace, automotive, energy, die/mold, and general manufacturing applications where productivity and reliability are critical.

Grade Details
The TA grade used in the SGS38833 end mill combines a sub-micron solid carbide substrate with a multi-layer PVD coating. It is engineered to deliver high hot hardness, low friction, and excellent crater and flank-wear resistance while retaining enough toughness for moderate interrupted cuts and high-speed machining of steels, stainless steels, and cast irons.
| Coating | Multi-layer PVD AlTiN-based |
| Hardness | ~93 HRA (>1700 HV30) |
| Grain Size | Sub-micron, ~0.5 µm |
| Rupture Strength | ~3,500 MPa |
| Key Performance | High hot hardness, low friction, superior crater/flank wear resistance |

Chipbreaker Profile
The SGS38833 uses an optimized flute and edge-geometry profile rather than a traditional turning-style chipbreaker. The five-flute variable-helix layout, polished flute surfaces, and controlled corner-radius edge preparation work together to control chip formation, reduce cutting forces, and suppress chatter in demanding milling operations.
- Variable helix angles: Break up harmonic vibration and improve dynamic stability at high spindle speeds.
- Polished flute surfaces: Reduce chip adhesion and built-up edge for smoother chip evacuation.
- Corner-radius edge preparation: Reinforces the cutting edge at the radius to resist chipping and extend tool life.
- Optimized core thickness: Provides the rigidity required for aggressive side milling and profiling cuts.
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended |
|---|---|---|
| Carbon & Low-Alloy Steels (P1‑P3) | Good | ✓ Yes |
| Alloy & Tool Steels (P4‑P5) | Moderate | ✓ Yes |
| Stainless Steels (M1‑M2) | Moderate | ✓ Yes |
| Hardened Steels (>45 HRC) | Difficult | ○ Limited |
| Gray & Ductile Cast Irons (K1‑K3) | Good | ✓ Yes |
| Aluminium & Non-Ferrous Alloys | Good | △ With Caution* |
| Titanium & Nickel-Based Superalloys | Difficult | ○ Limited |
*Use with caution on long-chipping aluminium; verify chip evacuation and reduce feed to prevent re-cutting.
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Slotting | ★★★☆☆ | Use reduced Ae and stable coolant flow |
| Side Milling / Profiling | ★★★★★ | Excellent surface finish and accuracy |
| Plunging | ★★★☆☆ | Centre-cutting design allows straight plunging |
| Ramping & Helical Interpolation | ★★★★☆ | Ideal for pocket opening and hole interpolation |
| Finishing | ★★★★★ | Tight corner radius produces clean fillets |
| Roughing | ★★★☆☆ | Light-to-medium roughing only; use adaptive strategy |
Recommended Cutting Conditions
| Material | Cutting Speed Vc | Feed Rate fn | Coolant |
|---|---|---|---|
| Carbon Steel | 180‑220 m/min | 0.05‑0.12 mm/tooth | Emulsion / mist |
| Alloy Steel | 120‑160 m/min | 0.05‑0.10 mm/tooth | Emulsion / high pressure |
| Stainless Steel | 100‑140 m/min | 0.04‑0.09 mm/tooth | High-pressure emulsion |
| Cast Iron | 140‑180 m/min | 0.06‑0.12 mm/tooth | Air / emulsion |
| Hardened Steel (>45 HRC) | 60‑100 m/min | 0.03‑0.07 mm/tooth | Minimal / air |
| Titanium Alloy | 40‑60 m/min | 0.04‑0.08 mm/tooth | High-volume emulsion |
Values are starting recommendations. Reduce speeds for long overhangs, poor fixturing, or difficult entry conditions.
Operating Guidelines
- Runout: Maintain total indicator runout below 0.010 mm at the tool tip; excessive runout causes uneven flank wear and early failure.
- Peck Cycle: When not using helical entry, limit straight plunge peck depth to 0.5‑1.0×D and fully retract to clear chips.
- Coolant: Use clean, filtered coolant at adequate pressure; aim nozzles at the cutting zone to prevent chip re-cutting.
- Entry Angle: Prefer ramp or helical entry at 1‑2° ramp angle; avoid direct 90° plunging into solid material.
- Speed/Feed: Start at the lower end of the recommended range and increase gradually while monitoring tool wear and sound.
- Tool Life: Inspect cutting edges for chipping, flank wear, and coating delamination after each shift; replace before quality degrades.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER32 Collet Chuck | ★★★★☆ | Use high-precision collet and correct torque |
| Hydraulic Holder | ★★★★★ | Best damping and runout control |
| Shrink-Fit Holder | ★★★★★ | Excellent rigidity for high-speed finishing |
| Side-Lock (Weldon) Holder | ★★★☆☆ | Acceptable for general milling; check runout |
| Milling Chuck | ★★★★☆ | Strong gripping force for roughing cuts |
