Halnn: The Ultimate Guide to Gun Drills

Gun drilling is a precision machining process designed for deep hole drilling with exceptional accuracy, surface finish, and straightness. At Halnn, we specialize in high-performance gun drills tailored for various industrial applications, ensuring superior efficiency and extended tool life.

 What is a Gun Drill?

A gun drill is a specialized cutting tool used for drilling deep and straight holes with high precision. It features a single straight flute for chip evacuation and internal coolant channels to facilitate heat dissipation and lubrication. This design enables gun drills to achieve depth-to-diameter ratios of up to 300:1, making them ideal for deep hole applications.
