1. Product Overview
The Kyocera SGS42731 is a 12 mm solid-carbide corner-radius end mill with four flutes, a 2.50 mm corner radius and TX/WF geometry. It is engineered for high-performance CNC milling of steels, stainless steels, cast irons and high-temp alloys, delivering excellent surface finish and long tool life.
2. ISO Designation Breakdown
| Code | Meaning |
|---|---|
| 12,0 | Nominal cutter diameter 12.0 mm |
| ENDMILL | Solid carbide end-mill family |
| 4FL | Four cutting flutes |
| 2,50R | Corner radius 2.50 mm |
| TX | Tolerance / dimensional class |
| WF | Edge preparation / wiper finish |
| SGS42731 | Manufacturer product code (MPN) |
3. Engineering Dimensions & Geometry
| Parameter | Value / Note |
|---|---|
| Nominal diameter (D1) | 12.0 mm |
| Corner radius (R) | 2.50 mm |
| Number of flutes (Z) | 4 |
| Tolerance code | TX |
| Edge condition | WF |
| Shank diameter | 12 mm (standard, confirm datasheet) |
| Overall length / helix | Refer to manufacturer datasheet |
4. Grade Details & Characteristics
- Substrate: Fine-grain solid carbide for high hardness and wear resistance.
- Coating: Advanced PVD AlTiN/TiAlN-type layer (grade-specific; refer to datasheet) for heat and oxidation resistance.
- Edge prep: WF micro-honing reduces chipping and improves surface finish.
- Performance: Stable in dry, MQL and flood-coolant machining at elevated speeds.
5. Grade Comparison Matrix
| Grade family | Coating | Characteristics | Typical application |
|---|---|---|---|
| Standard carbide | Uncoated | Economical, sharp edge | Aluminium, brass, plastics |
| AlTiN grade | PVD AlTiN | High heat resistance, long tool life | Steel, stainless steel, titanium |
| TiSiN grade | PVD TiSiN | Extreme hardness | Hardened steels >45 HRC |
6. Chipbreaker Profile
The four-flute geometry combines a continuous peripheral cutting edge with a 2.50 mm corner radius. The WF edge preparation acts as a micro-wiper, lowering cutting forces, splitting chips effectively and producing high-quality wall and floor finishes.
7. Recommended Applications & Materials
- Profile milling, contouring, shoulder milling and pocketing
- General-purpose slotting and finishing passes
- Carbon and alloy steels, stainless steels, cast iron
- Titanium and nickel-based alloys
- Hardened steels up to ~50 HRC (depending on carbide grade)
8. Application Map by Operation
| Operation | Suitability | Guidance |
|---|---|---|
| Face milling | Moderate | Light depths, secure workpiece |
| Slotting | Good | Use ramp/plunge entry where applicable |
| Profiling / contouring | Excellent | Radius protects sharp corners |
| Pocketing | Good | Maintain reliable chip evacuation |
| Ramping / helical | Moderate | Check centre-cutting capability |
| Finishing | Excellent | WF edge improves surface finish |
9. Recommended Cutting Conditions
Values are starting recommendations; optimize for machine rigidity, coolant and workpiece condition.
| Material | Vc (m/min) | fz (mm/tooth) | Depth / width guidance |
|---|---|---|---|
| Low-alloy steel | 80–140 | 0.05–0.10 | ap ≤ 1D, ae 0.5–1D |
| Stainless steel | 60–100 | 0.04–0.08 | Reduce Vc to control heat |
| Cast iron | 100–180 | 0.08–0.14 | Dry or compressed air |
| Titanium alloy | 40–70 | 0.04–0.08 | Rigid setup, flood coolant |
| Hardened steel | 60–100 | 0.03–0.06 | Light depths, high speed |
10. Operating Guidelines
- Use a precision collet, hydraulic or shrink-fit holder with minimum runout.
- Balance toolholder assembly to G2.5 or better for high-speed work.
- Keep total indicated runout below 0.01 mm at the cutting edge.
- Select coolant/lubrication method suited to material and grade coating.
- Apply ramping or helical entry for full-width slotting.
- Inspect cutting edges after each operation and replace worn tools promptly.
- Wear appropriate personal protective equipment.
11. Toolholder Compatibility
| Holder type | Compatible | Notes |
|---|---|---|
| ER collet chuck | Yes | Select correct 12 mm collet |
| Hydraulic expansion chuck | Yes | Best runout and surface finish |
| Shrink-fit holder | Yes | Ideal for high-speed milling |
| Side-lock / Weldon | Yes | Standard 12 mm shank fit |
| HSK / BT / CAT spindle | Machine dependent | Use balanced holder |
