Product Overview
The Kyocera SGS38838 1/2 inch solid carbide endmill is a five-flute precision cutting tool engineered for demanding CNC milling operations. Featuring a 0.010 inch corner radius and advanced TM-grade coating, this endmill delivers an optimal balance of surface finish, dimensional accuracy, and metal removal rate across a broad spectrum of ferrous and non-ferrous workpiece materials. The 5-flute configuration provides increased productivity in finishing and semi-finishing applications by allowing higher feed rates while maintaining excellent chip evacuation. Manufactured to Kyocera's stringent quality standards, this tool is suitable for aerospace, automotive, die and mould, and general precision engineering industries.

Grade Details
The TM grade is a high-performance micro-grain carbide substrate combined with a multi-layer PVD coating. It is specifically formulated to resist crater wear and flank wear at elevated cutting temperatures, making it ideal for medium-to-high speed machining of steels, stainless steels, and cast irons. The fine grain structure provides excellent edge integrity and a balance of hardness and toughness.

Chipbreaker Profile
The flute geometry of this 5-flute endmill is engineered with a variable helix and optimized core-to-edge ratio. The profile promotes efficient chip curling, controlled chip flow, and reduced cutting forces, which improves surface finish and extends tool life in semi-finishing and finishing operations.
- Variable helix design reduces harmonic vibration and chatter during high-speed cutting.
- Polished flute faces minimise chip adhesion and improve evacuation in slotting and pocketing.
- Positive rake geometry lowers cutting forces and heat generation.
- Core-reinforced body provides rigidity for stable machining of tough materials.
- 0.010" corner radius improves edge durability and produces consistent fillets.

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Roughing | ★★★★☆ | High material removal in stable setups |
| Semi-Finishing | ★★★★★ | Optimal balance of speed and finish |
| Finishing | ★★★★☆ | Excellent surface finish at lighter depths |
| Slotting | ★★★☆☆ | Use reduced ae; ensure chip evacuation |
| Profiling / Side Milling | ★★★★★ | Outstanding finish and accuracy |

Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed Rate fn (mm/tooth) | Coolant |
|---|---|---|---|
| Carbon Steel | 120 – 180 | 0.08 – 0.15 | Emulsion / Flood |
| Alloy Steel | 100 – 150 | 0.06 – 0.12 | Emulsion / Flood |
| Stainless Steel | 80 – 120 | 0.05 – 0.10 | Emulsion / Flood |
| Cast Iron | 100 – 160 | 0.08 – 0.14 | Air / Emulsion |
| Aluminium Alloys | 200 – 300 | 0.10 – 0.20 | Flood / Mist |
Operating Guidelines
- Runout: Maintain tool runout below 0.010 mm TIR to maximise tool life and surface finish.
- Peck Cycle: Not applicable to peripheral milling; for plunging use ramp entry or helical interpolation only.
- Coolant: Use ample coolant or minimum quantity lubrication to evacuate chips and control heat in the cutting zone.
- Entry Angle: Avoid direct 90° plunging. Employ helical or ramp entries to protect cutting edges.
- Speed/Feed: Start at the conservative end of recommended parameters and increase gradually based on machine stability and chip formation.
- Tool Life: Monitor flank wear regularly. Remove or replace the tool when flank wear reaches approximately 0.15–0.20 mm.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best runout and vibration damping |
| Shrink Fit Holder | ★★★★★ | Excellent rigidity for high-speed milling |
| ER Collet Chuck | ★★★★☆ | Use high-precision collet and proper torque |
| Milling Chuck | ★★★★☆ | Good gripping force for roughing |
| Side-Lock Holder | ★★★☆☆ | Acceptable; higher runout may reduce finish |
