High Quality Multi Specification Custom Deep Hole Drill Gun Drill

Product Introduction

Key Features

Superior Build Quality

• The gun drill is constructed from high-grade materials that ensure durability and long service life. The drill body is typically made from a strong and rigid alloy steel, capable of withstanding the high axial forces and vibrations associated with deep hole drilling. The cutting edges are crafted from high-speed steel or carbide, depending on the specific application requirements. Carbide tips, for example, offer excellent hardness and wear resistance, enabling them to maintain their sharpness even when drilling through tough materials. The surface finish of the drill is carefully controlled to minimize friction and heat generation during drilling. This not only improves the overall drilling efficiency but also helps to prevent tool damage and workpiece deformation.
• The precision manufacturing process ensures that each gun drill meets strict tolerances. The concentricity between the drill's cutting edges and the shank is maintained within a very narrow margin, which is crucial for achieving accurate hole diameters and straightness. This high level of precision also contributes to the drill's ability to produce smooth and clean hole surfaces, reducing the need for secondary finishing operations.

Customizable Specifications

• We offer a wide range of customizable options to meet the diverse needs of our customers. The diameter of the gun drill can be adjusted to suit specific hole size requirements, typically ranging from a few millimeters to several centimeters. The length of the drill can also be customized, allowing for the drilling of deep holes with varying depths. Different flute geometries are available, which can be optimized for different materials and cutting conditions. For example, a drill with a larger flute volume may be preferred for drilling materials that produce a large amount of chips, such as aluminum alloys, to ensure efficient chip evacuation. In contrast, a drill with a more streamlined flute design might be better suited for drilling harder and more brittle materials, like some types of steel or cast iron.
• The shank design of the gun drill can be tailored to fit different machine tool spindles. Whether it's a traditional Morse taper shank or a modern high-precision collet chuck shank, we can provide the appropriate configuration to ensure a secure and accurate fit. This customization not only enhances the performance of the drill but also improves the overall compatibility and versatility of the drilling operation.

Efficient Deep Hole Drilling Capability

• The gun drill is specifically designed for deep hole drilling, which requires a unique set of characteristics. It features a long and slender design with a coolant hole running through the center. This coolant hole allows for the continuous supply of cutting fluid directly to the cutting zone. The cutting fluid serves multiple purposes. It helps to cool the drill and the workpiece, reducing the risk of overheating and thermal damage. It also lubricates the cutting edges, minimizing friction and improving chip evacuation. The high-pressure coolant system, which can typically operate at pressures ranging from several hundred to several thousand pounds per square inch, forces the chips to be ejected from the hole in a continuous stream. This prevents chip clogging, which is a common problem in deep hole drilling and can lead to tool breakage and poor hole quality.
• The unique cutting geometry of the gun drill, including the angle and shape of the cutting edges, is optimized for deep hole drilling. It allows for efficient material removal while maintaining the stability of the drill. The combination of the drill's design, the coolant system, and the cutting geometry enables it to achieve high penetration rates and produce deep holes with excellent dimensional accuracy and surface finish.

Wide Range of Material Compatibility

• Our gun drill is capable of drilling a variety of materials. It can handle common metals such as steel, stainless steel, aluminum, and copper with ease. For steel drilling, it can adapt to different grades and hardness levels, from mild steel to high-strength alloy steels. When drilling stainless steel, its design and material composition help to overcome the challenges associated with the material's toughness and work hardening characteristics. In the case of aluminum, the drill's flute geometry and cutting edge sharpness are optimized to prevent chip adhesion and ensure smooth drilling. It can also be used for drilling other materials like cast iron, brass, and some composite materials, depending on the specific drill configuration and cutting parameters.
• The ability to work with such a wide range of materials makes this gun drill a versatile tool for many industries, including aerospace, automotive, machinery manufacturing, and more.

Application Scenarios

• In the aerospace industry, it is used for drilling holes in turbine engine components, such as turbine discs and shafts, where deep and precise holes are required.
• The automotive industry utilizes the gun drill for manufacturing engine blocks, cylinder heads, and transmission parts, ensuring accurate and efficient hole drilling.
• In the machinery manufacturing sector, it is essential for drilling deep holes in spindles, gears, and housings, contributing to the overall performance and reliability of the machinery.
• It can also be applied in the oil and gas industry for drilling holes in drill bits and other downhole tools.

Installation and Maintenance

• Installation: The gun drill is installed in a CNC machine or a dedicated deep hole drilling machine following the manufacturer's instructions. The shank is properly inserted into the spindle and secured using the appropriate clamping mechanism. The coolant supply system is connected to the drill's coolant hole, ensuring a proper flow of cutting fluid.
• Maintenance: Regular inspection of the gun drill is necessary. Check for signs of wear on the cutting edges, such as chipping or dulling. Inspect the coolant hole for any blockages and clean it if required. The drill should be stored in a clean and dry environment to prevent corrosion. Lubricate the shank and other moving parts as recommended by the manufacturer. If the drill shows significant wear or damage, it should be replaced or reconditioned to maintain optimal performance.
