Precision-engineered 20D Carbide Deep Hole Drill with AlTiSiN Coating
Designed for extreme-depth drilling (20× diameter) in carbon steel, alloy steel, and stainless steel. These drills combine ultra-fine grain carbide with advanced coolant-through technology for unmatched stability, efficient chip evacuation, and exceptional tool life in demanding industrial applications.
Key Features
- 20D Depth Ratio - Reliable performance for deep-hole drilling (up to 20 × diameter)
- Optimized Geometry - Parabolic flutes with split-point design for reduced thrust force and chip clogging
- High-Pressure Coolant Channels - Internal coolant holes (dual/triple) for effective heat and chip removal
- Wear-Resistant Coating - AlTiSiN/AlCrN coatings for enhanced heat resistance (up to 900°C)
- 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
