Product Overview
The Kyocera 0.028 ENDMILL 4FL BN SGM00763 is a precision-engineered solid carbide micro ball-nose endmill featuring a AlTiN coating and 4-flute design. Engineered for aerospace finishing, this tool delivers superior surface finish, tight dimensional tolerances, and extended tool life in high-precision CNC machining centers. The 4-flute configuration provides increased rigidity and higher feed rates compared to 2-flute designs, making it ideal for finishing operations where surface quality is paramount. The super micro-grain carbide substrate combined with advanced PVD coating technology ensures stable, predictable cutting performance across a wide spectrum of workpiece materials.

Grade Details - Key Grade Characteristics
The AlTiN grade is engineered specifically for precision finishing solid carbide endmills. Key characteristics include:
- Substrate: Super micro-grain carbide (0.4 μm grain size) for maximum hardness and edge stability
- Coating: Aluminum Titanium Nitride (AlTiN) PVD multi-layer coating optimized for finishing
- Coating Hardness: 3,300 HV for superior wear resistance in high-speed finishing
- Oxidation Temperature: 1,100°C enabling dry or minimal-lubrication machining
- Coating Thickness: 2-4 μm optimized for micro-tool edge retention and sharpness
- Surface Finish: Ultra-smooth coating surface reduces built-up edge and improves workpiece finish
- Color: Dark gray/black appearance for easy visual identification
Grade Comparison Matrix
| Grade | Coating | Best For | Max Temp | Hardness |
|---|---|---|---|---|
| AlTiN | AlTiN PVD | Steel, Hardened Steel, Titanium Finishing | 1,100°C | 3,300 HV |
| Uncoated | None | Aluminum, Copper, Plastics | 600°C | 1,800 HV |
| TiN | Titanium Nitride | General purpose, low-speed roughing | 600°C | 2,300 HV |
| TiAlN | TiAlN PVD | High-speed steel machining | 800°C | 2,800 HV |
| DLC | Diamond-Like Carbon | Non-ferrous, graphite | 400°C | 3,000 HV |
Chipbreaker Profile
As a solid carbide 4-flute endmill, chip control is achieved through integrated flute geometry rather than separate chipbreakers. The 0.028" 4FL BN features:
- Flute Profile: Tight-radius parabolic flute optimized for micro-chip formation and evacuation
- Core Thickness: 65% of tool diameter for maximum rigidity in finishing operations
- Rake Angle: 6° positive rake for fine chip control and reduced burr formation
- Clearance Angle: 10° primary clearance with 18° secondary clearance for minimal flank rubbing
- Chip Splitting: Variable helix angle (28°-32°) to suppress chatter and harmonic vibration
- Edge Preparation: Micro-honed cutting edge (0.005-0.010 mm) for enhanced edge stability

Application Map by Operation
| Operation | Recommended | Max Depth | Notes |
|---|---|---|---|
| 3D Contouring | ✓ Primary Use | 1.5×Dc | Stepover 0.03-0.08×Dc |
| Profiling | ✓ Recommended | 2.0×Dc | Climb milling preferred |
| Slotting | △ Caution | 0.8×Dc | Reduce feed by 40%; chip evacuation limited |
| Ramping | ✓ Recommended | 2.0×Dc | Max angle 1.5° |
| Plunging | ✗ Not Recommended | — | Use center-cutting tools only |
| Engraving | ✓ Excellent | 0.5×Dc | High spindle speed, light cuts |

Recommended Cutting Conditions
| Material | Vc (m/min) | Vc (SFM) | fz (mm/tooth) | RPM (approx) |
|---|---|---|---|---|
| Carbon Steel | 31 | 101 | 0.004-0.008 | 13,874 |
| Stainless Steel | 26 | 85 | 0.003-0.006 | 11,636 |
| Aluminum | 110 | 360 | 0.008-0.015 | 49,232 |
| Hardened Steel (50 HRC) | 18 | 61 | 0.002-0.004 | 8,324 |
| Titanium Alloy | 20 | 68 | 0.002-0.005 | 9,309 |
| Graphite | 160 | 524 | 0.010-0.020 | 71,610 |
Note: Values are starting recommendations for finishing passes. Reduce by 20-30% for semi-finishing. Adjust based on machine rigidity, coolant, and desired surface finish (Ra 0.2-0.4 μm achievable).
Operating Guidelines
- Runout: Maintain TIR < 0.003 mm (0.00012") for mirror surface finishes; use precision collets or shrink-fit holders
- Coolant: Flood coolant or MQL (Minimum Quantity Lubrication) recommended for steel and stainless; compressed air or mist for aluminum to prevent chip welding
- Entry: Use helical entry or ramping at 1-1.5° angle; avoid direct plunging with non-center-cutting 4FL tools
- Chip Evacuation: Compressed air blast highly recommended to prevent chip packing in 4-flute cavity; insufficient evacuation is the #1 cause of failure
- Speed/Feed: Start at 70% of recommended values for finishing; increase gradually while monitoring surface finish and tool wear
- Tool Life: Expected tool life is 90-150 minutes under optimal finishing conditions in carbon steel
- Inspection: Inspect cutting edges under 20× magnification after each job; replace at first sign of coating wear or edge chipping
- Surface Finish: For Ra < 0.4 μm, use stepover ≤ 0.05×Dc and feed per tooth at lower end of recommended range
Toolholder Compatibility
| Holder Type | Shank Diameter | Clamping | Recommended Brand |
|---|---|---|---|
| Collet Chuck (ER) | 0.125" / 3.175mm | ER11, ER16 | Kyocera, Rego-Fix, BIG Daishowa |
| Shrink Fit | 0.125" / 3.175mm | Hydro/shrink | Haimer, SCHUNK |
| Hydraulic Chuck | 0.125" / 3.175mm | Hydraulic clamp | Komet, Mapal |
| Milling Chuck | 0.125" / 3.175mm | Mechanical | NT Tool, Nikken |
Minimum clamping length: 3×shank diameter. Use dynamically balanced holders (G2.5 @ 30,000 RPM) for high-speed finishing. Runout < 0.003 mm is critical for 4FL micro finishing performance.
