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
