Product Overview
The SGM00904 is a premium solid carbide ball-nose endmill from Kyocera's SGM series, featuring a 0.027 inch (Ø0.686 mm) cutting diameter. Engineered with PR1535 ultra-fine grain carbide substrate and advanced PVD coating, this 4-flute design delivers exceptional performance in high-precision CNC milling operations. The ball-nose geometry is optimized for 3D contouring, die/mold finishing, and complex surface machining where mirror-finish quality and dimensional accuracy are critical.

Grade Details — Key Grade Characteristics
The PR1535 grade utilized in the SGM00904 represents Kyocera's advanced carbide technology platform:
- Substrate: Ultra-fine grain tungsten carbide (0.5 μm grain size) with 12% cobalt binder for optimal hardness-toughness balance
- Coating: Multi-layer PVD TiAlN (Titanium Aluminum Nitride) with nano-layered architecture, 3.5 μm total thickness
- Hardness: 92.5 HRA (1530 HV30) — ideal for hardened steel and high-speed applications
- Transverse Rupture Strength: 4200 MPa — exceptional resistance to chipping and micro-fracture
- Oxidation Resistance: Stable up to 900°C (1652°F) — enables dry machining and high-speed cutting
- Coating Adhesion: HF1 rating per ISO 26443 — superior coating bond strength prevents flaking
- Surface Finish: Mirror-polished flute surface (Ra 0.1 μm) minimizes built-up edge and improves chip flow
Grade Comparison Matrix
| Grade | Substrate | Coating | Hardness Range | Wear Resistance |
|---|---|---|---|---|
| PR1535 ★ | Ultra-fine grain | PVD TiAlN | 45–55 HRC | High |
| PR1725 | Sub-micron | PVD TiSiN | 50–60 HRC | Very High |
| PR1215 | Fine grain | PVD TiN | <45 HRC | Standard |
| PR1530 | Ultra-fine grain | PVD AlCrN | 45–55 HRC | High |
★ = Grade used in this product. PR1535 offers the best balance of wear resistance and toughness for general precision milling.
Chipbreaker Profile
The SGM series features an optimized flute geometry designed specifically for micro-machining applications:
- Flute Profile: Parabolic helix with variable core thickness for progressive chip evacuation
- Helix Angle: 30° constant helix — minimizes vibration and ensures smooth cutting action
- Rake Angle: 8° positive rake on peripheral cutting edge — reduces cutting forces and heat generation
- Clearance Angle: 12° primary clearance + 25° secondary clearance — prevents rubbing and improves surface finish
- Chip Pocket Volume: Optimized for 0.027in diameter — prevents chip packing in deep cavity machining
- Edge Preparation: Micro-honed cutting edge (0.003–0.005 mm radius) — enhances edge stability without sacrificing sharpness
- Center Cutting: Yes — capable of direct plunging and ramping operations
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Application Notes |
|---|---|---|---|
| Carbon Steels | P1-P3 | Excellent | First choice for general machining |
| Alloy Steels | P4-P5 | Excellent | High-speed finishing capability |
| Stainless Steels | M1-M2 | Very Good | Reduced built-up edge tendency |
| Cast Iron | K1-K3 | Good | Use compressed air for chip removal |
| Aluminum Alloys | N1-N3 | Very Good | Polished flute surface prevents adhesion |
| Titanium Alloys | S1-S2 | Good | Low cutting speed recommended |
| Hardened Steel (45-55 HRC) | H1-H2 | Very Good | Optimized for hard milling |
Application Map by Operation
| Operation Type | Suitability | Technical Guidance |
|---|---|---|
| 3D Contouring | Excellent | Optimal chip evacuation, smooth surface finish |
| Slot Milling | Good | Use reduced radial engagement for best results |
| Ramping | Very Good | Max ramp angle 3° recommended |
| Plunging | Good | Center-cutting design allows direct plunging |
| Profiling | Excellent | High precision wall finishing capability |
| Trochoidal Milling | Very Good | Ideal for high-efficiency slotting |
Recommended Cutting Conditions
Parameters below are starting recommendations. Adjust based on machine rigidity, workpiece fixturing, and coolant strategy.
| Workpiece Material | Cutting Speed (SFM) | Feed per Tooth (in) | Axial Depth (in) | Radial Depth (in) |
|---|---|---|---|---|
| Carbon Steel (AISI 1045) | 80 | 0.0008 | 0.012 | 0.004 |
| Stainless Steel (304) | 60 | 0.0006 | 0.010 | 0.003 |
| Tool Steel (H13) | 50 | 0.0005 | 0.008 | 0.003 |
| Aluminum (6061) | 120 | 0.0012 | 0.015 | 0.006 |
| Titanium (Ti-6Al-4V) | 40 | 0.0004 | 0.006 | 0.002 |
Operating Guidelines
- Runout Tolerance: Maintain tool runout below 0.0002 in (5 μm) for optimal tool life and surface finish
- Coolant Recommendation: Oil mist or minimum quantity lubrication (MQL) preferred for micro-machining; flood coolant acceptable for larger depths
- Entry Strategy: Use helical ramp entry (max 3° ramp angle) or trochoidal path to avoid shock loading
- Stepover for Finishing: 0.0004–0.0008 in (10–20 μm) for mirror-finish surfaces; 0.001–0.002 in for standard finishing
- Tool Overhang: Minimize overhang to 4× diameter or less; use shrink-fit or hydraulic chucks for best results
- Spindle Speed: Calculate RPM from SFM: RPM = (SFM × 3.82) / 0.027in. Ensure spindle capability exceeds required RPM
- Chip Load: Start at 50% of recommended feed for first trial; increase gradually while monitoring tool wear
- Tool Inspection: Inspect under 20× magnification after initial run; look for uniform wear land or coating integrity
Toolholder Compatibility
| Holder Type | Shank Diameter | Clamping Force | Recommended For |
|---|---|---|---|
| Shrink Fit Holder | 0.125 in | High (4–6 MPa) | High-speed finishing, best runout control |
| Hydraulic Chuck | 0.125 in | Medium-High | General purpose, vibration damping |
| Collet Chuck (ER16/ER20) | 0.125 in | Medium | Standard milling, good accessibility |
| Milling Chuck | 0.125 in | High | Heavy roughing, high torque transmission |
Note: Ensure holder TIR (Total Indicated Runout) is less than 0.0002 in at the tool tip for micro-machining applications.
