Custom Single-Fluted Deep Hole Gun Drills with Brazed Carbide Head

Product Introduction

Key Features

Brazed Carbide Head

• The brazed carbide head is the core component that provides exceptional cutting performance. Carbide is known for its remarkable hardness and wear resistance. It can withstand the abrasive forces encountered when drilling through tough materials such as hardened steels, stainless steels, and various alloys. The brazing process used to attach the carbide head to the drill body ensures a strong and reliable connection. This allows the drill to transfer the cutting forces effectively and maintain its integrity during the drilling operation. The geometry of the carbide head is precisely engineered. The cutting edge angles and shapes are optimized to promote efficient chip formation and minimize cutting forces. This results in a smoother drilling process and reduces the risk of tool breakage. The carbide head also has excellent heat resistance, which is crucial in deep hole drilling where heat dissipation can be a challenge. It helps to prevent overheating of the cutting edge, thereby prolonging the tool life and maintaining the accuracy of the drilled holes.
• The quality of the carbide used and the brazing technique are carefully controlled and monitored to ensure consistent and reliable performance.

Single-Fluted Design

• The single-fluted design offers several significant benefits. Firstly, it provides excellent chip evacuation capabilities. With only one flute, there is a larger space available for the chips to travel along as they are removed from the hole. This is especially important in deep hole drilling, where chip clogging can lead to tool failure and poor hole quality. The single flute also allows for a more efficient coolant flow. The coolant can be directed precisely to the cutting edge, providing effective cooling and lubrication. This helps to reduce heat generation and friction, further enhancing the drill's performance and prolonging its life. Additionally, the single-fluted design results in a more stable drilling process. It reduces the vibration and chatter that can occur with multi-fluted drills, leading to more accurate hole diameters and better surface finishes.
• The flute geometry is optimized to ensure a smooth and continuous chip flow, and it is carefully matched with the carbide head geometry to achieve maximum drilling efficiency.

Customizability

• These gun drills offer a high degree of customization. The diameter of the drill can be 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, allowing for the drilling of deep holes with varying depths. Different flute geometries and carbide head configurations are available to suit different materials and cutting 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 machine tool spindles, ensuring a proper and secure connection. This customization allows for the drill to be optimized for a wide range of applications, from small-scale precision machining to large industrial manufacturing processes.
• The ability to customize the drill based on specific needs makes it a versatile tool for various industries, including aerospace, automotive, machinery manufacturing, and more.

Durable and High-Quality Construction

• The overall construction of the drill is built to last. The body of the drill is made from a high-strength alloy steel that provides excellent rigidity and support for the brazed carbide head. The surface finish of the drill 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 drill is manufactured to strict quality control standards, ensuring that each unit meets the highest levels of performance and reliability. The combination of the brazed carbide head, single-fluted design, and durable construction results in a drill that can withstand the rigors of continuous deep hole drilling operations and maintain its accuracy and efficiency over time.
• The reliable construction of the drill also reduces the need for frequent tool replacements, saving both time and costs in the manufacturing process.

Application Scenarios

• In the aerospace industry, used for drilling deep holes in turbine engine components, such as discs and shafts, for cooling channels and fuel supply systems.
• The automotive industry benefits from these drills in manufacturing engine blocks and cylinder heads, creating deep holes for coolant passages and piston sleeves.
• In the machinery manufacturing sector, ideal for drilling deep holes in spindles, gears, and housings, where precise hole geometries are needed for proper assembly and function.
• Can also be applied in the manufacturing of firearms and other defense-related equipment, where deep hole drilling is required for barrels and other components.

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.
• Maintenance: Regular inspection of the drill is necessary. Check for signs of wear on the carbide head, 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.
