Description

3 points carbide heavy duty drill manufactures for hard steel

Introduction:

Engineered for extreme durability in drilling hardened steels (HRC 45-65), these high-performance carbide drills feature 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
