Engineered for Extreme Durability

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

Key Features

Solid Micro-Grain Carbide - Ultra-hard substrate for exceptional wear resistance in abrasive materials
2-Flute Geometry - Optimized for balanced chip evacuation and rigidity in deep-hole drilling
Advanced Coating - TiAlN/AlCrN coating provides heat resistance up to 1,000°C
Split-Point Design - Reduces thrust force and prevents walking for precise drilling

Performance Advantages

3× longer tool life compared to standard carbide drills in D2, H13, and 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
