A Gun Drill is a specialized deep hole drilling tool originally developed for manufacturing gun barrels—hence the name. It is designed to drill very deep and precise holes with excellent straightness, roundness, and surface finish.
Gun drills find extensive use in industries such as aerospace, automotive, mold making, medical devices, and hydraulics. They are favored for their ability to produce high-quality holes with precision and efficiency.
Key Features
Deep Hole Capability:
Capable of drilling depths exceeding 100 times the diameter (100×D) or more.
High Precision:
Excellent straightness, roundness, and surface finish.
Single-Flute Design:
Easier chip evacuation, though it requires slower feed rates.
Internal Coolant Flow:
Enables continuous cutting and efficient chip removal.
