3 points carbide heavy duty drill manufactures for hard steel
Introduction:
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
