Custom Durable Deep Hole Drilling Deep Hole Drill Tools Gun Drill

Product Introduction

Key Features

Durable Construction

• The gun drill is built to last. The body is typically made from a high-strength alloy steel that provides excellent rigidity and resistance to deformation. This is crucial as deep hole drilling exerts significant axial and torsional forces on the tool. The cutting edges are crafted from premium carbide, renowned for its extreme hardness and wear resistance. Carbide can withstand the abrasive nature of the materials being drilled, such as hardened steels, stainless steels, and various alloys. The combination of the strong steel body and the carbide cutting edges ensures a long service life. The drill's surface finish is carefully controlled to minimize friction and heat generation. A smooth surface helps to improve chip evacuation and reduces the risk of tool wear and workpiece damage. The overall construction is engineered to withstand the rigors of continuous deep hole drilling, reducing the need for frequent tool replacements and minimizing downtime.
• The manufacturing process adheres to strict quality control standards, ensuring that each gun drill is of the highest quality and reliability.

Deep Hole Drilling Capability

• This gun drill is specifically designed for deep hole drilling. It features a long and slender design with a central coolant hole. The coolant, which can be a cutting oil or a water-soluble emulsion, is pumped at high pressure through this hole and directed to the cutting edges. The coolant serves multiple essential functions. It cools the drill and the workpiece, preventing overheating and maintaining the integrity of the cutting edges. It also lubricates the cutting process, reducing friction and facilitating chip evacuation. The unique flute design of the gun drill is optimized to work in conjunction with the coolant system. The flutes are shaped to guide the chips along with the coolant stream, ensuring efficient removal of chips from the hole. This helps prevent chip clogging, which is a common challenge in deep hole drilling and can lead to tool breakage and poor hole quality. The long length and rigidity of the gun drill enable it to create deep holes with high straightness and dimensional accuracy.
• The gun drill's design is optimized to maintain stability and minimize vibration during drilling, further enhancing the quality of the drilled holes and prolonging the life of the tool.

Customizability

• We offer a high degree of customizability for our deep hole drilling gun drill. The diameter of the drill can be precisely adjusted to meet specific hole size requirements, typically ranging from a few millimeters to several centimeters. The length of the drill can also be customized to accommodate different depth needs, with options available from relatively short to extremely long lengths. Different flute geometries and coolant hole configurations can be selected based on the target material and drilling conditions. For example, a more aggressive flute geometry may be suitable for softer materials, while a more refined geometry is preferred for harder and more brittle materials. The shank design of the drill can be tailored to fit different machine tool spindles, ensuring proper and secure attachment. This customization allows our gun drill to be optimized for a wide range of applications, from small-scale precision machining to large-scale industrial manufacturing.
• The ability to customize the gun drill based on specific requirements makes it a versatile tool for various industries, including aerospace, automotive, machinery manufacturing, and more.

Precision Engineering

• Our gun drill is manufactured with a high level of precision. The geometry of the cutting edges is meticulously designed to optimize chip formation and evacuation. The point angle and helix angle are precisely determined to ensure efficient material removal and minimal cutting forces. This results in a smoother drilling process and reduces the risk of tool breakage. The drill's concentricity is maintained within extremely tight tolerances, which is crucial for achieving accurate hole diameters and straightness. The surface finish of the drill is also carefully controlled to reduce friction and heat generation. A smooth surface helps the drill to glide through the material more easily, improving the overall drilling efficiency and the quality of the hole surface. Advanced manufacturing techniques and strict quality control processes are employed to ensure that each gun drill meets the highest standards of precision and performance.
• The precision engineering of this gun drill results in high-quality holes with excellent surface finishes, reducing the need for secondary finishing operations in many cases.

• In the aerospace industry, used for drilling deep holes in turbine engine components, such as discs, shafts, and casings, for cooling channels, fuel supply systems, and structural integrity.
• The automotive industry benefits from these gun drills in manufacturing engine blocks, cylinder heads, and transmission parts, creating deep holes for coolant passages, piston sleeves, and other critical components.
• In the machinery manufacturing sector, ideal for drilling deep holes in spindles, gears, housings, and other precision components, where accurate hole geometries and depths are essential for proper assembly and function.
• Can also be applied in the oil and gas industry for drilling holes in drill bits, downhole tools, and pipes, as well as in the manufacturing of firearms and other defense-related equipment.

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 at the required pressure.
• Maintenance: Regular inspection of the gun drill is necessary. Check for signs of wear on the cutting edges, such as chipping, dulling, or coating degradation. Inspect the coolant hole for any blockages and clean it if required. The gun 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 gun drill shows significant wear or damage, it should be replaced or reconditioned to maintain optimal performance. Periodic calibration of the machine and the gun drill may also be required to ensure continued precision and accuracy.
