1. Product Overview
The Kyocera 7/8 ENDMILL 3FL SQ TN SGS39773 is a 3-flute solid carbide square end mill for high-performance CNC milling. Its balanced geometry reduces cutting forces, improves chip evacuation and delivers consistent surface finish across steel, stainless steel and cast iron.
2. ISO Designation Breakdown
| Element | Interpretation |
|---|---|
| MPN | SGS39773 |
| Cutting diameter | 7/8 in (22.225 mm) |
| Flute count | 3FL = 3 flutes |
| End style | SQ = square / 90° corner |
| Application group | ISO 513 P/M/K solid carbide end mill |
3. Engineering Dimensions & Geometry
| Parameter | Value |
|---|---|
| Cutting diameter (D1) | 7/8 in / 22.225 mm |
| Shank diameter (D2) | 7/8 in / 22.225 mm |
| Overall length (L1) | 3.0 in / 76.2 mm (typical) |
| Length of cut (L2) | 1.75 in / 44.45 mm (typical) |
| Corner radius | Square (0 mm) |
| Helix angle | 30° - 45° |
| Tolerance | h6 (typical) |
4. Grade Details & Characteristics
- Grade / MPN: SGS39773
- Substrate: Micro-grain solid carbide
- Coating: Advanced PVD/TiAlN-type wear-resistant coating
- Edge preparation: Precision ground square cutting edge
- Performance: High hardness, heat resistance and extended tool life
5. Grade Comparison Matrix
| Grade | Substrate | Coating | Best suited for |
|---|---|---|---|
| SGS39773 | Micro-grain carbide | PVD/TiAlN | Steel, stainless steel, cast iron |
| General 2-flute | Standard carbide | Uncoated/TiN | Aluminium, general machining |
| General 4-flute | Standard carbide | TiAlN | Finishing, high-speed steel |
6. Chipbreaker Profile
This 3-flute design uses a high-helix flute profile with a sharp square cutting edge rather than an indexable chipbreaker. The flute geometry creates natural chip curl, splits chips into manageable lengths and directs evacuation away from the cut zone.
7. Recommended Applications & Materials
- Carbon and alloy steels (ISO P)
- Stainless steels (ISO M)
- Cast iron (ISO K)
- High-temp alloys at reduced speeds
- General engineering and mould/die machining
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Slotting | Excellent | Full-width cuts up to 1xD |
| Profiling / side milling | Excellent | Use ae up to 0.5xD for stability |
| Pocketing | Good | Preferred ramp/helical entry |
| Finishing | Good | Light depth and high speed |
| Roughing | Moderate | Use reduced ae/ap and rigid setup |
9. Recommended Cutting Conditions
Starting parameters for stable CNC mills; adjust based on machine, fixture and material condition.
| Work material | Vc (m/min) | fz (mm/tooth) | ap max | Coolant |
|---|---|---|---|---|
| Mild / carbon steel | 120 - 180 | 0.05 - 0.10 | 1xD | Emulsion / air |
| Alloy steel | 90 - 140 | 0.04 - 0.08 | 1xD | Emulsion |
| Stainless steel | 70 - 110 | 0.04 - 0.07 | 0.8xD | High-pressure coolant |
| Cast iron | 100 - 160 | 0.06 - 0.12 | 1xD | Air / minimal coolant |
10. Operating Guidelines
- Use a rigid toolholder and minimum overhang.
- Secure workpiece and verify run-out below 0.01 mm.
- Start with lower speeds/feeds and increase progressively.
- Apply adequate coolant for stainless and alloy steels; cast iron often machines dry or with air blast.
- Inspect cutting edges before each use; replace if chipping or coating wear is visible.
11. Toolholder Compatibility
| Holder type | Interface / size | Notes |
|---|---|---|
| ER collet chuck | ER25 / ER32 / 22 mm collet | Common on BT40/ISO40 spindles |
| End mill holder | 7/8 in Weldon / side-lock | High torque, good rigidity |
| Shrink-fit holder | 7/8 in bore | Best run-out and balance for HSM |
| Hydraulic holder | 7/8 in clamping | Damping for long overhang |
