About Gun Drills

A Gun Drill is a special type of drill used for making deep, precise holes, originally developed for drilling gun barrels — hence the name. It is widely used in industries like automotive, aerospace, mold making, and medical devices.

Structure
  • Single Cutting Edge: Simplifies chip removal and reduces vibration.
  • Guide Pads: Help maintain straightness and improve surface finish.
  • Internal Coolant Channel: High-pressure coolant flows through the tool to cool and remove chips.
  • Long, Thin Drill Tube: Ideal for deep holes — up to 100 times the diameter or more.
Advantages
  • Excellent for deep hole drilling
  • Produces high-precision holes with smooth surfaces
  • Efficient chip evacuation with internal coolant
  • Commonly used for gun barrels, engine parts, molds, and surgical tools
 

Features:

Advantages of Gun Drills

Excellent Deep Hole Capability

Can drill holes over 100× diameter (D)

Ideal for deep, narrow, and precision bores

High Hole Accuracy

Superior straightness, roundness, and coaxiality

Typically achieves IT8–IT10 tolerance levels

Smooth Surface Finish

Surface roughness can reach Ra 0.4–1.6 µm, reducing the need for reaming or honing

Efficient Chip Removal

Internal high-pressure coolant flushes chips out smoothly

Prevents clogging and overheating

Stable and Low Vibration Drilling

Guide pads stabilize the tool and reduce tool deflection

Suitable for long and precise holes

Long Tool Life (with proper use)

With correct speeds, feeds, and coolant, gun drills maintain sharpness over long runs

Carbide-tipped or solid carbide options available

Applicable to Various Materials

Effective on steel, aluminum, copper, titanium, plastic, and other metals or composites

Automation-Friendly

Can be used in CNC machines, gun drilling machines, or modified lathes
