Carbide Step Drill Bit With AlTiN Coating Spiral Flute Internal Coolant For Hard Metals
Introduction:
Features:
✔ Advanced AlTiN Coating
Withstands temperatures up to 800°C
Provides superior abrasion resistance for extended tool life
Ideal for dry or semi-dry machining conditions
✔ Optimized Spiral Flute Design
30°-45° helix angle for improved chip evacuation
Reduces cutting forces and prevents chip clogging
Delivers smoother surface finishes vs. straight flute designs
✔ Internal Coolant System
2-4 coolant holes (Ø1.0-1.5mm) direct lubricant to cutting edges
Enables higher feed rates and deeper hole drilling
Prevents workpiece hardening in heat-sensitive alloys
✔ Solid Micro-Grain Carbide Substrate
Sub-micron carbide grain structure for exceptional hardness
Maintains edge integrity in materials up to HRC 65
3-5× longer lifespan than HSS or TiN-coated tools
✔ Multi-Step Geometry
Eliminates tool changes for tapered holes, countersinking, and deburring
Precision ground cutting edges for ±0.02mm dimensional accuracy
50% Higher Cutting Speeds vs. conventional coated drills
Exceptional Chip Control in gummy materials like Inconel and titanium
Reduced Power Consumption due to efficient cutting geometry
Interchangeable with standard ER collet and hydraulic chucks
Applications:
Aerospace - Drilling turbine blades, engine components
Medical Devices - Precision holes in surgical implants
Die/Mold Making - Hardened steel cavities (HRC 50+)
Energy Sector - Valve bodies, drilling equipment
Automotive - Transmission gears, turbocharger parts
