1. Product Overview
The Kyocera 25,0 ENDMILL 4FL SQ SGS40185 is a solid-carbide square end mill engineered for precision CNC milling. Its 25 mm diameter and four-flute configuration deliver high material-removal rates, stable chip evacuation, and excellent surface finish in general engineering, mould-and-die, and aerospace production.
2. ISO Designation Breakdown
The part-code structure identifies the tool geometry and product series:
- 25,0 — nominal cutting diameter in millimetres (25 mm)
- ENDMILL — solid-carbide end-mill tool family
- 4FL — four flutes for semi-finishing and finishing
- SQ — square end geometry (90° corner)
- SGS40185 — Kyocera product / ordering code
3. Engineering Dimensions & Geometry
| Parameter | Value / Description |
| Cutting Diameter (D) | 25.0 mm |
| Number of Flutes | 4 |
| Corner Geometry | Square (90° end) |
| Shank Diameter | 25.0 mm (ISO h6 typical) |
| Overall Length | Per Kyocera SGS40185 specification |
| Helix Angle | Standard 30°–45° (grade dependent) |
| Coating | Advanced wear-resistant carbide grade coating |
4. Grade Details & Characteristics
Built on a premium sub-micrograin carbide substrate, the SGS40185 grade offers:
- High transverse rupture strength for demanding interrupted cuts
- Excellent edge stability and heat resistance
- Advanced coating for reduced built-up edge and extended tool life
- Balanced hardness/toughness for steel and cast-iron machining
5. Grade Comparison Matrix
| Variant | Corner | Best For |
| SGS40185 | Square | Slotting, profiling, 90° shoulder milling |
| SGS40186 | Ball Nose | 3D contouring, finishing, die & mould |
6. Chipbreaker Profile
The four-flute geometry is engineered with a stable core and open flutes for efficient chip evacuation. The cutting-edge design balances shearing action with chip curl control, reducing cutting forces and improving wall-surface finish in slotting and profiling passes.
7. Recommended Applications & Materials
- Carbon and alloy steels
- Stainless steels (pre-machining and finishing)
- Grey and nodular cast iron
- Hardened steels up to approx. 50–55 HRC (grade dependent)
- General engineering, aerospace and die & mould components
8. Application Map by Operation
| Operation | Suitability |
| Slotting | Excellent (up to 1×D axial depth) |
| Side / Shoulder Milling | Excellent |
| Profiling | Excellent |
| Pocketing | Good |
| Plunging | Limited (ramp-in recommended) |
9. Recommended Cutting Conditions
Starting parameters for a 25 mm four-flute carbide end mill; adjust based on machine rigidity and material condition:
| Material | Vc (m/min) | fz (mm/tooth) |
| Mild / Low-Carbon Steel | 120–180 | 0.08–0.14 |
| Alloy Steel | 80–150 | 0.06–0.12 |
| Stainless Steel | 60–100 | 0.05–0.10 |
| Grey Cast Iron | 100–160 | 0.08–0.14 |
| Hardened Steel (50 HRC) | 40–80 | 0.03–0.08 |
10. Operating Guidelines
- Use minimum runout toolholding (≤0.01 mm) to protect cutting edges and maximise tool life.
- Start with conservative axial depth and increase once tool behaviour is confirmed.
- For slotting, keep axial depth (ap) at or below 1×D; use ramp or helical entry instead of direct plunging.
- Apply appropriate coolant or compressed-air blast to clear chips and reduce thermal cycling.
- Verify spindle speed and feed calculations for the actual flute count and workpiece material.
11. Toolholder Compatibility
Compatible with standard high-precision milling toolholders:
- ER collet chucks (minimum TIR)
- Hydraulic expansion chucks
- Shrink-fit holders
- Milling chucks / high-torque holders
12. Packaging & Ordering Info
Supplied as a genuine Kyocera industrial cutting tool. Each unit is individually packaged with the manufacturer part number (MPN) SGS40185 clearly marked for traceability. Order by MPN for exact replacement.
