TiCN Coated Straight Shank Gun Drills 10-20mm Diameter For Accurate Deep Hole Drilling
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

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.
