The Alliance Tools Deep Hole Drilling System is designed for precision drilling of holes with depth-to-diameter ratios exceeding 10:1. This specialized system includes a set of gun drills with internal coolant channels that deliver cutting fluid directly to the cutting edge, ensuring efficient chip evacuation and preventing overheating during deep drilling operations.
The carbide-tipped drills feature single-lip geometry optimized for straight, accurate holes in challenging materials. The system includes 5 drill diameters (3mm, 4mm, 5mm, 6mm, and 8mm) with effective drilling depths up to 30 times their diameter.
Each drill incorporates a specialized point geometry that minimizes thrust forces and ensures excellent centering accuracy. This professional system is ideal for mold making, aerospace components, and precision engineering applications where hole straightness and surface finish are critical requirements.
The Alliance Tools Deep Hole Drilling System represents the culmination of advanced drilling technology specifically designed to address the unique challenges of deep hole drilling. This professional-grade system enables machinists and engineers to produce exceptionally straight, accurate holes with depth-to-diameter ratios that far exceed the capabilities of conventional drilling methods.
At the heart of this system are specialized gun drills that incorporate several key technological innovations:
The integrated coolant delivery system is a critical component that enables successful deep hole drilling:
This system includes 5 precision-manufactured gun drills covering the most commonly used diameters for deep hole applications: 3mm, 4mm, 5mm, 6mm, and 8mm. Each drill is capable of producing holes with depth-to-diameter ratios up to 30:1, allowing for exceptional versatility across various applications.
Each drill incorporates a carefully engineered point geometry that provides several critical advantages:
The system comes complete in a custom-designed case that includes:
