Product Description:

A Gun Drill is a specialized type of drill designed for creating deep and precise holes, initially developed for the purpose of drilling gun barrels — hence its name. This tool finds widespread application in various 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

Applications:

 

Gun drills find application in various industries where there is a need for deep, straight, and precise holes. Some common industries that benefit from the use of gun drills include:

  • Firearms Industry: Gun barrels are initially where gun drills were used, requiring exceedingly straight and high-precision bores.
  • Automotive Industry:
    • Engine components such as crankshafts, camshafts, and connecting rods.
    • Fuel system parts including injectors, valve bodies, and oil passages.
    • Transmission and hydraulic systems necessitating precision deep bores.
  • Aerospace Industry:
    • Hydraulic manifolds and landing gear parts.
    • Structural components that require lightweight deep bores.

Mold and Die Making: Gun drills are used for creating cooling channels in injection molds or die-casting tools to ensure accurate and efficient heat dissipation paths.

Medical Devices: They are utilized for making bone drills, cannulas, and needle tubes, crafting precision small-diameter, high-quality holes.

Hydraulics & Pneumatics: In this sector, gun drills are employed for valve bodies, cylinders, and pressure blocks, necessitating precise axial bores for fluid control.

General Manufacturing: Any component that requires a deep, accurate, and clean hole in metal, plastic, or composite materials can benefit from the application of gun drills.
