Product Overview
The Kyocera SGS38824 is a 3/8 inch diameter, 5-flute solid carbide corner-radius endmill designed for high-performance CNC milling operations. Featuring a 0.090 inch corner radius and advanced TM-series carbide grade, this precision cutter delivers exceptional surface finish, dimensional stability, and extended tool life in finishing to medium-duty machining applications. The optimized 5-flute geometry provides a balance between chip evacuation and cutting-edge strength, making it ideal for profiling, slotting, and contouring of alloy steels, stainless steels, and cast irons on modern machining centers.

Grade Details - Key Grade Characteristics
The SGS38824 utilizes Kyocera's TM-series fine-grain carbide substrate, engineered specifically for solid endmill applications requiring high wear resistance and thermal stability. The advanced PVD coating reduces friction and provides exceptional oxidation resistance at elevated cutting temperatures, making this grade ideal for high-speed finishing and light-to-medium machining operations.
| Coating | Multi-layer PVD (TiAlN-based) |
| Hardness | 92.0 HRA / 1,700 HV |
| Grain Size | Sub-micron fine grain (0.6 µm) |
| Rupture Strength | ≥ 3,500 N/mm² |
| Key Performance | High wear resistance, excellent heat resistance, low friction |
Grade Comparison Matrix
| Grade | Wear Resistance | Toughness | Heat Resistance | Finish Quality | Applications |
|---|---|---|---|---|---|
| SGS Standard | ★★★☆☆ | ★★★★☆ | ★★★☆☆ | ★★★☆☆ | General purpose |
| SGS-TM (This Tool) | ★★★★☆ | ★★★☆☆ | ★★★★☆ | ★★★★★ | Finishing, high-speed |
| SGS-HP Premium | ★★★★★ | ★★★★☆ | ★★★★★ | ★★★★☆ | Hardened steels, hard milling |
Chipbreaker Profile
The 5-flute geometry of the SGS38824 is optimized with variable helix angles and carefully designed chip pockets to promote stable chip formation and efficient evacuation. The profile minimizes harmonic vibration and reduces the risk of chip recutting, especially during high-speed profiling and finishing passes.
- Variable helix design suppresses chatter and harmonic vibration
- Wide chip pockets improve evacuation in slotting and pocketing
- Positive rake face reduces cutting forces and heat generation
- Polished flute surface minimizes chip adhesion on sticky materials
- Strong core geometry provides rigidity for stable finishing cuts

Recommended Cutting Conditions
| Material | Cutting Speed Vc | Feed Rate fn | Coolant |
|---|---|---|---|
| Low-Carbon Steel | 120 - 180 m/min | 0.08 - 0.15 mm/tooth | Emulsion / Air |
| Alloy Steel | 80 - 140 m/min | 0.06 - 0.12 mm/tooth | Emulsion |
| Stainless Steel | 60 - 100 m/min | 0.05 - 0.10 mm/tooth | Emulsion / MQL |
| Cast Iron | 100 - 160 m/min | 0.08 - 0.14 mm/tooth | Air / Emulsion |
| Aluminum Alloy | 200 - 400 m/min | 0.10 - 0.20 mm/tooth | Air / MQL |
| Hardened Steel | 40 - 80 m/min | 0.03 - 0.08 mm/tooth | Emulsion / Oil |
Operating Guidelines
- Runout: Maintain total indicated runout below 0.01 mm at the tool tip. Excessive runout causes uneven flute loading and premature corner wear.
- Peck Cycle: Use continuous pecking for deep pockets; reduce axial depth of cut (ap) to 1×D in slotting and 1.5×D–2×D for profiling.
- Coolant: Apply copious coolant or MQL to control heat. Avoid thermal shock by maintaining consistent coolant flow, especially in stainless steel and titanium.
- Entry Angle: Use ramp or helical entry angles between 2°–5°. Avoid direct 90° plunging unless the tool is specified as centre-cutting.
- Speed/Feed: Start at the lower end of recommended cutting data and increase gradually based on machine rigidity and chip formation.
- Tool Life: Monitor flank wear and corner radius wear. Re-sharpen or replace when flank wear exceeds 0.15 mm or when surface finish degrades.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER Collet Chuck | ★★★★☆ | Suitable for most finishing applications; ensure correct collet size |
| Hydraulic Chuck | ★★★★★ | Excellent runout and damping for high-speed finishing |
| Milling Chuck | ★★★★☆ | Good grip and torque transmission |
| Shrink Fit Holder | ★★★★★ | Best runout and rigidity for precision milling |
| Side-Lock Endmill Holder | ★★★☆☆ | Acceptable; check runout and gripping length |
