Gun drills are a specific type of deep hole drilling tool that was initially created for the production of gun barrels, hence the name. These tools are engineered to bore extremely deep and accurate holes while maintaining exceptional straightness, roundness, and surface finish quality. The applications of gun drills are extensive, spanning across industries such as aerospace, automotive, mold making, medical devices, and hydraulics.

The specialized design of these tools enables them to perform intricate drilling tasks with unparalleled accuracy and consistency. Their use is particularly prominent in advanced manufacturing sectors where the demand for high-quality holes is critical to the overall performance and functionality of the end product.
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.
