Description

20D Carbide deep hole drill with AlTiSiN coating for steel

Introduction:

Precision-engineered for extreme-depth drilling (20× diameter) in carbon steel, alloy steel, and stainless steel. Combining ultra-fine grain carbide with advanced coolant-through technology, these drills deliver unmatched stability, efficient chip evacuation, and exceptional tool life in demanding industrial applications.

Features:

1.20D Depth Ratio – Reliable performance for deep-hole drilling (up to 20× diameter)


2.Optimized Geometry – Parabolic flutes + split-point design for reduced thrust force and chip clogging


3.High-Pressure Coolant Channels – Internal coolant holes (dual/triple) for effective heat and chip removal


4.Wear-Resistant Coating – AlTiSiN/AlCrN coatings for enhanced heat resistance (up to 900°C)


5.Rigid Shank Design – Precision-ground tolerance (h6) for minimal runout

Performance Advantages:


30% longer tool life vs. conventional carbide drills


Superior hole straightness (±0.1mm/100mm)


Reduced cycle time with aggressive feeds (up to 0.3mm/rev)

Typical Applications:


• Oil & gas (valve bodies, drilling components)


• Automotive (transmission shafts, hydraulic cylinders)


• Mold making (ejection pin holes, coolant channels)


• Energy (turbine blades, boiler tubes)
