Product Description
Engineered for extreme performance in hard metal machining, this carbide step drill bit features a wear-resistant AlTiN coating, high-efficiency spiral flutes, and precision internal coolant channels to conquer the most challenging drilling applications.
Key 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
- 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
- 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
Performance Advantages:
- 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
