3 Points Carbide Heavy Duty Drill for Hard Steel
Engineered for Extreme Durability

These high-performance carbide drills are designed for drilling hardened steels (HRC 45-65). Featuring a robust 2-flute design optimized for high feed rates, superior chip control, and extended tool life in demanding industrial applications.

Features
  • Solid Micro-Grain Carbide - Ultra-hard substrate for wear resistance in abrasive materials
  • 2-Flute Geometry - Balanced chip evacuation and rigidity for deep-hole drilling
  • Advanced Coating - TiAlN/AlCrN for heat resistance (up to 1,000 °C)
  • Split-Point Design - Reduces thrust force and prevents walking
Performance Advantages
  • 3 × longer tool life vs. standard carbide drills in D2, H13, 4340 steels
  • Higher feed rates (up to 0.25mm/rev) without compromising hole quality
  • Exceptional hole straightness (±0.05mm per 100mm depth)
Typical Applications
  • Die & Mold - Hardened tool steel drilling (P20, S7)
  • Aerospace - Landing gear components, turbine shafts
  • Oil & Gas - Drill collars, valve bodies
  • Automotive - Transmission gears, crankshafts
