Custom Deep Hole Drilling Carbide Insert Index Drill

Product Introduction

Key Features

Carbide Inserts

• The carbide inserts used in this drill are the key to its exceptional cutting performance. Carbide is known for its remarkable hardness, second only to diamond in some cases. This hardness allows the inserts to cut through a wide range of materials, including hardened steels, stainless steels, and various alloys, with ease. The inserts also possess excellent wear resistance, ensuring a long service life. They can maintain their sharpness and cutting efficiency over an extended period of drilling operations, reducing the frequency of tool replacements. This not only saves costs but also minimizes production downtime. The geometry of the carbide inserts is precisely engineered. 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 carbide inserts are available in different grades and coatings, allowing for customization based on the specific material and drilling conditions. For example, a particular coating may be applied to enhance the insert's resistance to heat and friction when drilling high-temperature alloys.

Indexable Design

• The indexable design of this drill offers several significant advantages. Firstly, it allows for quick and easy replacement of the carbide inserts. When one insert becomes worn or damaged, it can be easily indexed or replaced without having to remove the entire drill from the machine. This reduces tool changeover time and increases productivity. The indexable design also provides flexibility in terms of cutting edge geometry. Different inserts with varying geometries can be used depending on the application requirements. For example, a more aggressive cutting edge may be selected for rough drilling, while a finer edge can be used for finishing operations. This versatility makes the drill suitable for a wide range of drilling tasks, from initial hole creation to achieving precise final hole dimensions. Additionally, the indexable design helps to distribute the cutting forces more evenly across the inserts, reducing the risk of tool breakage and improving the overall stability of the drilling process.
• The indexing mechanism is designed to be highly accurate and reliable, ensuring that the inserts are properly positioned and locked in place during drilling.

Deep Hole Drilling Capability

• This drill is specifically engineered for deep hole drilling. It features a long and slender design with a coolant hole running through the center. 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 purposes. It cools the drill and the workpiece, preventing overheating and maintaining the integrity of the carbide inserts. It also lubricates the cutting process, reducing friction and improving the surface finish of the hole. The high-pressure coolant helps to flush the chips away from the cutting zone and out of the hole. The flute design of the drill is optimized to facilitate the smooth flow of chips along with the coolant. The combination of the coolant system and the flute geometry ensures that chips are effectively removed, preventing chip clogging and tool breakage. The drill's long length and rigidity allow it to create deep holes with high accuracy and straightness.
• The deep hole drilling capability of this tool makes it suitable for applications in industries such as aerospace, automotive, and machinery manufacturing, where deep and precise holes are often required.

Precision Engineering

• Our carbide insert index drill is manufactured with a high level of precision. The overall design of the drill, including the shank, body, and the attachment of the carbide inserts, is carefully engineered to ensure optimal performance. The shank is designed to fit securely into the machine spindle, minimizing runout and maximizing concentricity. The body of the drill is made from a high-strength alloy steel that provides the necessary rigidity to support the carbide inserts during drilling. The surface finish of the drill is 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. The precision engineering of this drill results in high-quality holes with excellent surface finishes, reducing the need for secondary finishing operations.
• Advanced manufacturing techniques and quality control processes are employed to ensure that each drill meets the strictest standards of precision and performance.

Application Scenarios

• In the aerospace industry, used for drilling deep holes in turbine engine components, such as discs and shafts, 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. They can create deep holes for coolant passages, piston sleeves, and other critical components.
• In the machinery manufacturing sector, ideal for drilling deep holes in spindles, gears, and housings, where precise hole geometries and depths are needed for proper assembly and function.
• Can also be applied in the oil and gas industry for drilling holes in drill bits and downhole tools, 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.
• Maintenance: Regular inspection of the drill is necessary. Check for signs of wear on the carbide inserts, 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.
