Custom TiN Coated Carbide Drill Bit, Drill Head for Gun Drill

Product Introduction

Key Features

Carbide Substrate

• The carbide substrate is the foundation of our drill bit and drill head. Carbide is renowned for its remarkable hardness, which allows it to cut through a variety of tough materials such as hardened steels, stainless steels, and alloys. It exhibits excellent wear resistance, ensuring a long service life and reducing the frequency of tool replacements. This durability is crucial in industrial applications where downtime for tool changes can be costly. The carbide's high heat resistance is also a significant advantage. During the drilling process, a substantial amount of heat is generated. Carbide can effectively dissipate this heat, preventing the drill from overheating and maintaining the integrity of the cutting edge. The specific grade of carbide used is carefully selected based on the target material to be drilled, optimizing the performance and longevity of the tool.
• The microstructure of the carbide is engineered to provide a balance between hardness and toughness, enabling it to withstand the rigors of drilling without chipping or breaking.

TiN Coating

• The TiN coating applied to the carbide drill bit and drill head offers several key benefits. TiN is known for its golden color and excellent hardness and wear resistance properties. The coating provides a hard and protective layer that further enhances the wear resistance of the tool. It helps to reduce friction between the drill and the workpiece, which in turn lowers the cutting forces required. This reduction in cutting forces leads to less energy consumption and less heat generation during drilling. The TiN coating also improves the surface finish of the drilled holes. It prevents the adhesion of workpiece material to the drill, reducing the likelihood of built-up edge formation. This results in cleaner and more accurate holes. The thickness of the TiN coating can be precisely controlled to optimize its performance for different drilling applications.
• The coating process is carried out using advanced techniques to ensure a uniform and adherent coating, maximizing its effectiveness.

Gun Drill Design Compatibility

• These drill bits and drill heads are specifically designed to be used in gun drill systems. They feature a long and slender profile with a central coolant hole. The coolant, which can be a cutting fluid or emulsion, is pumped at high pressure through this hole and directed to the cutting edges. The design of the drill bit and drill head is optimized to work in conjunction with the gun drill's coolant system. The flutes are shaped to ensure efficient chip evacuation, guiding the chips along with the coolant stream out of the hole. This helps prevent chip clogging, which is a common issue in deep hole drilling and can lead to tool breakage and poor hole quality. The long length and rigidity of the drill bit and drill head enable them to create deep holes with high straightness and dimensional accuracy, meeting the strict requirements of industries such as aerospace, automotive, and machinery manufacturing.
• The compatibility with gun drill systems allows for seamless integration into existing drilling setups, enhancing productivity and precision.

Customizability

• We offer a high degree of customizability for our TiN coated carbide drill bits and drill heads. 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 used for softer materials, while a more refined geometry is suitable for harder and more brittle materials. The shank design of the drill can be tailored to fit different gun drill machine spindles, ensuring a proper and secure connection. This customization allows the drill bits and drill heads to be optimized for a wide range of applications, from small-scale precision machining to large-scale industrial manufacturing.
• The ability to customize based on specific needs makes these tools a versatile choice for various industries, including aerospace, automotive, machinery manufacturing, and more.

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 high precision and durability of the drill bits and drill heads are essential for these critical applications.
• The automotive industry benefits from these tools in manufacturing engine blocks, cylinder heads, and transmission parts. They can drill deep holes for coolant passages, piston sleeves, and other critical components, improving the overall performance and reliability of the automotive systems.
• In the machinery manufacturing sector, ideal for drilling deep holes in spindles, gears, housings, and other precision components. The customizability of the drill bits and drill heads allows for the creation of holes with the exact specifications required for proper assembly and function, enhancing the performance of the machinery.
• 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 bit or drill head is installed in a gun drill 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 bit or drill head is necessary. Check for signs of wear on the TiN coating, such as peeling or scratching, and on the carbide substrate, 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. Periodic calibration of the machine and the drill may also be required to ensure continued precision and accuracy.
