Premium Carbide Step Drill Bit with AlTiSiN Coating
Designed for high-performance machining of hardened steels and exotic alloys, this carbide step drill bit combines AlTiSiN coating, straight flute design, and internal coolant channels to deliver exceptional tool life and precision in demanding industrial applications.
Key Features
- Advanced AlTiSiN Coating - Superior heat resistance (up to 900°C) and oxidation protection for extended tool life in high-temperature operations.
- Straight Flute Design - Optimized chip evacuation reduces clogging and improves surface finish in viscous materials.
- Internal Coolant Holes - Direct coolant to the cutting edge for heat dissipation, enabling higher feed rates and deeper hole drilling.
- Solid Carbide Construction - Ultra-hard substrate maintains sharpness in abrasive materials like tool steel, stainless, and titanium.
- Multi-Step Geometry - Eliminates tool changes for tapered/stepped hole applications (e.g., chamfering, deburring).
Performance Advantages
3× Longer Lifespan - AlTiSiN coating reduces flank wear vs. uncoated/TiN drills.
Higher Feed Rates - Internal coolant allows aggressive machining without workpiece hardening.
Versatile Material Compatibility - Engineered for stainless steel (304/316), titanium (Grade 5), Inconel, and hardened steels (HRC 45+).
Industrial Applications
- CNC Machining Centers - Ideal for deep-hole drilling in molds/dies.
- Aerospace Components - Drilling turbine blades and high-strength alloys.
- Automotive Manufacturing - Precision holes in gearboxes and drivetrain parts.
- Oil & Gas Tools - Machining valve bodies and drilling equipment.
