A gun drill is a specialized cutting tool used for deep-hole drilling. It is a long, straight tool that has a cutting edge at one end and a cooling system at the other end. The cooling system is used to cool the cutting edge and the workpiece during the drilling process. This helps to reduce heat buildup and extend the life of a gun drill. Gun drills are capable of drilling deep holes up to several meters in length and are known for their high cutting efficiency, reduced cutting force, and improved tolerance control.

Gun Drill Advantages

Gun Drills are a popular choice for deep-hole drilling in industries where precision, efficiency, and accuracy are critical. Gun drills have many advantages over traditional drilling methods including:

  • Deep Hole Capability: Ability to drill deep holes up to several meters in length with high accuracy, making them ideal for applications that require deep hole drilling, including aerospace, medical, and energy industries.
  • Straightness and Surface Finish: Produce straight holes with a smooth surface finish, critical in precision drilling applications.
  • High Cutting Efficiency: Uses a unique cutting action that results in high cutting efficiency and a longer tool life when compared to traditional drilling methods.
  • Minimal Heat Generation: Generate minimal heat during the drilling process, which helps to reduce the risk of thermal damage to the workpiece and the tool.
  • Reduced Cutting Force: Have a reduced cutting force compared to traditional drilling methods, which reduces the stress on the machine and the tool, increasing the tool life.
  • Improved Tolerance Control: Improved tolerance control results in more consistent and accurate hole size and position.
  • Versatility: Gun drills are versatile and can be used on a wide range of materials, including stainless steel, aluminum, titanium, and high-strength alloys.

Types of Gun Drills

Solid Carbide Gun Drills Made entirely from carbide, a very hard and wear-resistant material, solid carbide gun drills are ideal for drilling hard materials like titanium, stainless steel, and high-strength alloys.

Brazed Gun Drills Made from a steel shank and a carbide cutting head that is brazed onto the end, brazed gun drills are versatile and can be used on a wide range of materials including aluminum, brass, and plastic.

Indexable Gun DrillsWith an indexable cutting insert that is replaceable, indexable gun drills are more cost-effective than solid carbide or brazed gun drills. These are commonly used for drilling softer materials such as cast iron and low-carbon steel.

Coolant-Fed Gun DrillsThese gun drills have a coolant channel built into the shank to deliver coolant to the cutting edge, with the coolant helping to reduce heat buildup and extend the life of the tool. Coolant-fed gun drills are commonly used for drilling deep holes in materials such as stainless steel and high-temperature alloys.

Trepanning Gun Drills These gun drills have a cutting edge that forms a ring-shaped groove around the drill hole. This ring-shaped groove can be removed, leaving a solid cylinder in the center. Trepanning gun drills are used for drilling holes that require a core sample, such as in the oil and gas industry.

Industries 

Deep hole drilling machines are known for their ability to drill deep, straight holes with high accuracy and a smooth surface finish. This makes them ideal for applications where precision and a smooth surface are critical. Gun drilling machines are used in industries including aerospace, automotive, medical, energy, manufacturing, mining, and more.

Gun Drill Alternative Names

Gun drills are referred to by several different names which reflect their unique capabilities and characteristics, which set them apart from other drilling methods and make them a popular choice for deep hole drilling applications. Alternative names include:

  • Deep Hole Drills Because of their capability to drill deep holes with high accuracy, gun drills are often used interchangeably with deep hole drills.
  • BTA Drills BTA or “bottoming and through” drills refer to the ability of gun drills to drill both blind and through holes.
  • Gun Reamers Because gun drills have a reaming action that produces a smooth surface finish, they’re sometimes referred to as gun reamers.
  • Gun Taps With a tapping action that creates internal threads in a drilled hole, gun drills are sometimes referred to as gun taps.
  • Deep Hole Boring Bars Due to their long-straight design and capability to produce precise, straight holes, gun drills are also referred to as deep hole boring bars.

From deep, precise, and accurate holes to smooth surface finishes, longer tool life, and improved machining performance, gun drills are the perfect choice for anyone looking to achieve high-quality results and increased productivity in deep-hole drilling applications.
