6. Chipbreaker Profile
The SGS37973 features an optimized chipbreaker geometry specifically designed for 5fl high-efficiency milling. The flute profile incorporates a variable helix design (38° primary helix with 35°-41° variation) that breaks harmonic vibration and ensures stable chip evacuation even at aggressive depths of cut.

| Flute Profile | Variable helix, parabolic core | Vibration damping, chip curl control |
| Rake Face Angle | 8° positive radial, 4° axial | Reduced cutting force, lower heat |
| Chip Pocket Volume | Optimized for 1.0 diameter | Prevents chip recutting |
| Edge Preparation | T-land + honed radius (0.02 mm) | Edge strength + finish quality |
| Corner Radius Geometry | 0.090R profile | Enhanced corner durability |
7. Recommended Applications & Workpiece Materials
This endmill is ideally suited for the following material groups and application scenarios:
- Carbon Steels (AISI 1010–1055): Excellent performance in roughing to finishing operations. Recommended for die and mold manufacturing.
- Alloy Steels (AISI 4140, 4340): Ideal for aerospace components and automotive transmission parts requiring tight tolerances.
- Stainless Steels (304, 316, 17-4PH): Superior chip control and edge stability with TM grade.
- Cast Irons (GG20–GG40, GGG50): High wear resistance ensures consistent performance in gray and ductile iron machining.
- Titanium & Nickel Alloys: Optimized for Ti-6Al-4V and Inconel 718 with controlled heat generation.
- General Engineering: Versatile enough for prototype work, small-batch production, and high-volume manufacturing.
8. Application Map by Operation
| Operation Type | Suitability | Recommended Materials | Notes |
|---|---|---|---|
| Profile Milling | Excellent | Steel, SS, Ti | Full depth engagement recommended |
| Slot Milling | Very Good | Steel, Cast Iron | Use climb milling for best finish |
| Pocket Milling | Excellent | Steel, SS | Helical entry preferred |
| Ramping | Good | Steel, Ti | Max 3° ramp angle |
| Plunge Milling | Very Good | Steel, Cast Iron | Center-cutting capable |
| Helical Interpolation | Excellent | Steel, SS | Excellent hole quality achievable |
9. Recommended Cutting Conditions
The following parameters serve as starting recommendations. Always optimize based on machine rigidity, workpiece setup, and coolant delivery.
| Workpiece Material | Vc (m/min) | fz (mm/tooth) | ap × ae |
|---|---|---|---|
| Stainless Steel (316L) | 90-130 | 0.06-0.12 | 0.5-1.0D |
| Titanium (Ti-6Al-4V) | 50-80 | 0.05-0.10 | 0.3-0.8D |
| Inconel 718 | 30-50 | 0.03-0.06 | 0.2-0.5D |
| Hardened Steel (48-52 HRC) | 60-90 | 0.04-0.08 | 0.3-0.6D |
| Duplex Stainless Steel | 70-100 | 0.05-0.10 | 0.3-0.8D |
Note: Vc = Cutting speed; fz = Feed per tooth; ap = Axial depth of cut; ae = Radial depth of cut. Values assume stable machine conditions and adequate coolant.
10. Operating Guidelines
- Tool Runout: Maintain maximum runout of 0.01 mm at the tool tip. Excessive runout will reduce tool life dramatically.
- Coolant Recommendation: Use high-pressure through-spindle coolant (70+ bar) for best chip evacuation and thermal management. External flood coolant is acceptable for lower-speed operations.
- Entry Strategy: For pocket milling, use helical ramping or pre-drilled entry holes. Avoid direct plunge into solid material where possible.
- Depth of Cut: For finishing, use ae = 0.1–0.2 × D1. For roughing, ae up to 0.5 × D1 is acceptable with reduced speeds.
- Chip Load: Start at the lower end of the recommended fz range and increase gradually while monitoring tool wear and surface finish.
- Tool Life Monitoring: Inspect cutting edges after every 30 minutes of cutting time. Look for uniform flank wear; replace when VBmax = 0.2 mm.
- Storage: Store in original packaging away from moisture and corrosive atmospheres. Avoid contact between cutting edges.
11. Toolholder Compatibility
| Holder Type | Specification | Compatibility |
|---|---|---|
| Hydraulic Chuck | HSK-A63 / HSK-A100 | Excellent – recommended for finishing |
| Shrink Fit Holder | HSK-A63, ISO 40 taper | Excellent – best rigidity and runout control |
| Collet Chuck (ER) | ER32, ER40 precision collets | Good – ensure collet is in good condition |
| Milling Chuck | Standard milling chucks | Good – suitable for general milling |
| Side Lock (Weldon) | Standard Weldon flat | Acceptable – may limit runout precision |
For optimal performance, combine with Kyocera-approved toolholders and ensure TIR (Total Indicated Runout) does not exceed 0.01 mm at 3×D projection.
