1. Product Overview
The Kyocera SGS39629 is a 4-flute solid carbide square endmill with a 1/4 in. cutting diameter. It is designed for high-speed CNC slotting, side milling, profiling, and general finishing operations requiring sharp corners and accurate geometry.
- Precision micro-grain carbide substrate
- Square end geometry for sharp-corner milling and slotting
- 4-flute design for balanced chip removal and surface finish
- Wear-resistant coating for higher cutting speeds and longer tool life
2. ISO Designation Breakdown
| Code | Meaning |
|---|---|
| 1/4 | Nominal cutting diameter in inches |
| ENDMILL | End milling cutter |
| 4FL | Four flutes |
| SQ | Square end / 90° corner |
| TC | Solid tungsten carbide construction |
| SGS39629 | Manufacturer product/order code |
3. Engineering Dimensions & Geometry
| Parameter | Value | Notes |
|---|---|---|
| Cutting diameter | 1/4 in. (6.35 mm) | +0/-0.010 mm |
| Corner radius | 0 (sharp square end) | 90° corner profile |
| Number of flutes | 4 | Right-hand cut |
| Helix angle | 30° - 35° | Typical; smooth chip evacuation |
| Cutting length | ~22 mm (typical) | Confirm with datasheet |
| Overall length | ~57 mm (typical) | Confirm with datasheet |
| Shank diameter | 6.35 mm (h6) | Precision ground |
4. Grade Details & Characteristics
Grade family: Kyocera SGS39629 solid carbide endmill grade.
- Substrate: fine/micro-grain tungsten carbide for high hardness and edge strength.
- Coating: multi-layer PVD wear-resistant coating for heat and abrasion resistance.
- Hardness: ~92 HRA (carbide body).
- Edge preparation: sharp ground edge for clean wall and floor finishes.
5. Grade Comparison Matrix
| Grade / Type | Speed | Wear resistance | Best use |
|---|---|---|---|
| SGS39629 (coated carbide) | High | Excellent | Slotting, profiling, finishing |
| Uncoated carbide | Medium | Good | Non-ferrous, plastics |
| HSS-Co | Low | Moderate | General purpose, low cost |
6. Chipbreaker Profile
Four precision-ground helical flutes with a square end profile produce small, controlled chips and efficient evacuation. The center-cutting design allows direct plunging and helical interpolation.
- Flute form: helical gash, polished flutes
- Chip space: balanced for slotting and side-milling chip loads
- Center cutting: yes
- Ramping capability: up to approximately 3-5° recommended depending on material
7. Recommended Applications & Materials
- Carbon and alloy steels up to ~45 HRC
- Stainless steels (machining grades)
- Cast iron
- Titanium and heat-resistant alloys at reduced speeds
- Non-ferrous metals (aluminium, brass) with appropriate speeds
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Slotting | Excellent | Square end, 4 flutes |
| Side milling / profiling | Excellent | Stable wall finish |
| Pocketing | Good | Reduce ae for corners |
| 3D profiling | Limited | Use ball-nose tool |
9. Recommended Cutting Conditions
Starting values for stable machine setups; adjust according to rigidity, coolant, and part geometry.
| Material | Vc (m/min) | fz (mm/tooth) | ap / ae |
|---|---|---|---|
| Carbon steel | 120 - 180 | 0.03 - 0.06 | ap ≤1D; ae 0.2-0.5D |
| Stainless steel | 80 - 120 | 0.02 - 0.04 | ap ≤1D; ae 0.2-0.4D |
| Cast iron | 100 - 150 | 0.03 - 0.05 | ap ≤1D; ae 0.3-0.6D |
| Aluminium alloy | 250 - 400 | 0.05 - 0.10 | ap ≤1D; ae 0.3-0.7D |
10. Operating Guidelines
- Mount with the shortest overhang to reduce deflection and vibration.
- Use collet or shrink-fit holders with TIR ≤10 µm at the cutting tip.
- Apply suitable coolant or air blast to clear chips from the slot.
- Reduce radial engagement for deep pockets or weak workholding.
- Check spindle speed and feed calculations before starting the cut.
11. Toolholder Compatibility
- ER16/ER20/ER25 spring collet chucks with 1/4 in. or 6.35 mm collet
- Hydraulic or shrink-fit holders for high-speed finishing
- Standard end-mill holders with set screws for general milling
- Minimum recommended clamping length: 2.5x shank diameter
12. Packaging & Ordering Info
- Sold as one (1) piece per order unit
- Supplied in protective plastic sleeve or tube to prevent edge damage
