Gun Drills – High-Precision Deep Hole Drilling Solutions
Gun drills are specialized cutting tools designed for deep hole drilling applications where accuracy, straightness, and surface quality are critical. At Snijer, we manufacture high-performance gun drills engineered to deliver exceptional results in demanding industrial environments.
Thanks to their unique geometry and internal coolant channels, Snijer gun drills ensure reliable chip evacuation, reduced heat generation, and consistent hole quality even at very high length-to-diameter ratios.
What Is a Gun Drill?
A gun drill is a single-lip deep hole drilling tool featuring:
An internal coolant channel for direct cooling at the cutting edge
A V-shaped or straight flute for controlled chip evacuation
A guide pad system that ensures excellent hole straightness and roundness
Gun drills are typically used for drilling holes with length-to-diameter ratios of 10:1 up to 100:1, where conventional drills are no longer effective.
