Custom Durable Cemented Carbide Gundrill Deep Hole Drill Bits

Product Introduction

Key Features

Cemented Carbide Material

• The use of cemented carbide as the primary material for our gundrill bits provides numerous advantages. Cemented carbide is renowned for its extreme hardness, which allows it to effortlessly cut through a variety of tough materials, including hardened steels, stainless steels, and alloys. It exhibits excellent wear resistance, enabling the drill bits to maintain their sharpness and cutting efficiency over an extended period of drilling. This durability significantly reduces the frequency of tool replacements, thereby minimizing production downtime and costs. Additionally, cemented carbide has superior heat dissipation capabilities. Deep hole drilling generates a significant amount of heat, and the efficient heat transfer properties of cemented carbide help prevent overheating of the drill bit and the workpiece. This is crucial for maintaining the integrity of the cutting edge and ensuring accurate hole dimensions and surface finishes. The specific composition and microstructure of the cemented carbide can be optimized to suit different drilling applications and target materials.
• The high-quality cemented carbide used in our drill bits is carefully selected and processed to ensure consistent and reliable 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. This coolant hole allows for the continuous supply of high-pressure coolant, typically a cutting fluid or emulsion, directly to the cutting edge. The coolant serves multiple essential functions. It cools the drill bit and the workpiece, reducing the risk of thermal damage and maintaining the hardness and sharpness of the cutting edge. It also lubricates the cutting process, minimizing 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 challenge 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 drilling, further enhancing the quality of the drilled holes and prolonging the life of the drill bit.

Customizability

• We offer a high degree of customizability for our cemented carbide gundrill deep hole drill bits. The diameter of the drill bit can be precisely adjusted to meet specific hole size requirements, typically ranging from a few millimeters to several centimeters. The length of the drill bit 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 bit can be tailored to fit different machine tool spindles, ensuring proper and secure attachment. This customization allows our drill bits 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 bits based on specific requirements makes them a versatile tool for various industries, including aerospace, automotive, machinery manufacturing, and more.

Durability and Longevity

• The combination of the cemented carbide material and the optimized gundrill design results in drill bits with exceptional durability and longevity. The high hardness and wear resistance of the cemented carbide ensure that the drill bits 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 drill bits 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 bits also translates into cost savings over the long term, as they require less maintenance and replacement compared to conventional drill bits.
• The reliable performance and long service life of our cemented carbide gundrill deep hole drill bits make them 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 drill bits 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 bits are 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 bit's coolant hole, ensuring a proper flow of cutting fluid at the required pressure.
• Maintenance: Regular inspection of the drill bits 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 drill bits 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 bits show significant wear or damage, they should be replaced or reconditioned to maintain optimal performance. Periodic calibration of the machine and the drill bits may also be required to ensure continued precision and accuracy.
