Product Description:

A Gun Drill is a specialized type of drill designed for creating deep, accurate holes, originally created for drilling gun barrels — thus its name. It is widely utilized in industries such as 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
