Gun Drill: 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.
Applications: Gun drills are widely used in industries like aerospace, automotive, mold making, medical devices, and hydraulics.
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.
