Grade Details - Key Grade Characteristics
The AlTiN grade is engineered specifically for micro-precision solid carbide endmills. Key characteristics include:
- Substrate: Super micro-grain carbide (0.4 μm grain size) for high hardness and edge sharpness
- Coating: Aluminum Titanium Nitride (AlTiN) PVD multi-layer coating
- Coating Hardness: 3,300 HV for superior wear resistance
- Oxidation Temperature: 1,100°C enabling dry machining capabilities
- Coating Thickness: 2-4 μm optimized for micro-tool edge retention
- Color: Dark gray/black appearance for easy identification
Grade Comparison Matrix
| Grade | Coating | Best For | Max Temp | Hardness |
|---|---|---|---|---|
| AlTiN | AlTiN PVD | Steel, Hardened Steel, Titanium | 1,100°C | 3,300 HV |
| Uncoated | None | Aluminum, Copper, Plastics | 600°C | 1,800 HV |
| TiN | Titanium Nitride | General purpose, low speeds | 600°C | 2,300 HV |
| TiAlN | TiAlN PVD | High-speed steel machining | 800°C | 2,800 HV |
Chipbreaker Profile
As a solid carbide endmill, the chip control geometry is integrated into the flute design rather than a separate chipbreaker. The 0.027" 2FL BN features:
- Flute Profile: Parabolic flute design optimized for micro-chip evacuation
- Core Thickness: 60% of tool diameter for maximum rigidity in micro-machining
- Rake Angle: 8° positive rake for reduced cutting forces and improved surface finish
- Clearance Angle: 12° primary clearance with 20° secondary clearance
- Chip Splitting: Variable pitch flute spacing to minimize harmonic vibration

Note: Values are starting recommendations. Adjust based on machine rigidity, coolant application, and desired surface finish.
Operating Guidelines
- Runout: Maintain TIR < 0.005 mm (0.0002") for optimal tool life and surface finish
- Coolant: Flood coolant or mist recommended for steel and stainless; compressed air preferred for aluminum to prevent chip recutting
- Entry: Use helical entry or ramping at 1-2° angle; avoid direct plunging
- Chip Evacuation: Ensure adequate chip evacuation to prevent re-cutting and built-up edge
- Speed/Feed: Start at 80% of recommended values and increase gradually while monitoring tool wear
- Tool Life: Expected tool life is 60-120 minutes under optimal conditions in carbon steel
- Inspection: Inspect cutting edges under magnification after each job; replace at first sign of coating delamination
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 |
