Carbide Step Drill Bit with AlTiSiN Coating Straight Flute Internal Coolant for Steel Hard Metals
Introduction:
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).
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+).
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.
