Product Introduction

Key Features

Sintered Tungsten Carbide Tips

• The sintered tungsten carbide tips are the key to the outstanding cutting performance of our gun drill. Tungsten carbide is known for its remarkable hardness, which is second only to diamond in some measures. This hardness allows the tips to effortlessly penetrate and cut through a variety of tough materials, including hardened steels, stainless steels, and various alloys. The wear resistance of sintered tungsten carbide is also outstanding. It can maintain its sharpness and cutting efficiency over an extended period of drilling, significantly reducing the frequency of tool replacements. This not only saves costs but also minimizes production downtime. The sintering process used to fabricate the carbide tips ensures a dense and homogeneous structure, enhancing its mechanical properties. The tips are carefully engineered with precise geometries. The cutting edge angles and shapes are optimized to promote efficient chip formation and evacuation. They are designed to produce small, well-defined chips that can be easily removed from the hole, preventing chip clogging and ensuring a smooth drilling process.
• The quality of the sintered tungsten carbide used is of the highest grade, and its composition can be adjusted based on the specific material to be drilled, further optimizing the drill's performance.

Gundrill Design

• The gundrill design is specifically tailored for deep hole drilling. It features a long and slender body with a central coolant hole. High-pressure coolant, usually a cutting fluid or emulsion, is pumped through this hole and directed precisely 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 tungsten carbide tips. It also lubricates the cutting process, reducing friction and facilitating chip evacuation. The unique flute design of the gundrill 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 obstacle in deep hole drilling and can lead to tool breakage and poor hole quality. The long length and rigidity of the gundrill enable it to create deep holes with high straightness and dimensional accuracy.
• The gundrill design is engineered to maintain stability and minimize vibration during the drilling process, further enhancing the quality of the drilled holes and prolonging the life of the drill.

Customizability

• We offer a high degree of customizability for our sintered tungsten carbide tipped gundrill. 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 drill based on specific requirements makes it a versatile tool for various industries, including aerospace, automotive, machinery manufacturing, and more.

Durability and Longevity

• The combination of the sintered tungsten carbide tips and the optimized gundrill design results in a drill with exceptional durability and longevity. The high hardness and wear resistance of the carbide tips ensure that the drill can withstand the abrasive forces and stresses of deep hole drilling. The efficient heat dissipation and chip evacuation mechanisms help prevent premature wear and damage. These drills can endure a large number of drilling cycles without significant degradation in performance. This not only reduces the need for frequent tool replacements but also contributes to consistent and reliable production processes. The durability of our drill also translates into cost savings over the long term, as it requires less maintenance and replacement compared to conventional drill bits.
• The reliable performance and long service life of our sintered tungsten carbide tipped gundrill make it a valuable asset in any manufacturing operation that involves deep hole drilling.

Application Scenarios

• 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 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 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 drill is necessary. Check for signs of wear on the tungsten carbide tips, such as chipping, dulling, or coating degradation. 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. Periodic calibration of the machine and the drill may also be required to ensure continued precision and accuracy.
