Custom Three Sides Index Iscar Insert Drills for Deep Hole Processing

Product Introduction

Key Features

Iscar Inserts

• The Iscar inserts used in these drills are a hallmark of quality and performance. These inserts are crafted from advanced carbide materials, known for their outstanding hardness and wear resistance. They can effortlessly cut through a variety of tough materials, including hardened steels, stainless steels, and high-strength alloys. The precise geometry of the Iscar inserts is engineered to optimize chip formation and evacuation. Their cutting edges are sharp and durable, ensuring efficient material removal and a smooth drilling process. The inserts are available in different grades and coatings, allowing for customization based on the specific material and drilling conditions. For example, a specialized coating can enhance the insert's resistance to heat and corrosion, prolonging its service life and maintaining cutting performance in harsh environments.
• The high-quality Iscar inserts contribute to the overall precision and reliability of the drill, enabling it to produce accurate and high-quality deep holes.

Three Sides Indexable Design

• The three sides indexable design offers several significant advantages. Firstly, it provides enhanced tool life and cost-effectiveness. When one side of the insert becomes worn, it can be easily indexed to a new, sharp side without having to replace the entire insert. This significantly reduces tool changeover time and the frequency of insert replacements, saving both time and costs in the manufacturing process. The three-sided design also allows for greater flexibility in cutting strategies. Different cutting geometries can be utilized on each side, depending on the specific requirements of the drilling operation. For example, one side may be optimized for rough drilling to quickly remove material, while another side can be used for semi-finishing or finishing operations to achieve the desired hole surface finish and dimensional accuracy. This versatility makes the drill suitable for a wide range of deep hole processing tasks, from initial hole creation to final precision machining.
• The indexing mechanism is designed to be highly accurate and reliable, ensuring that the inserts are properly positioned and locked in place during drilling, thereby maintaining consistent hole quality.

Deep Hole Processing Capability

• These drills are specifically engineered for deep hole processing. They feature a long and slender design with a well-designed coolant hole. The coolant, which can be a high-performance cutting fluid, is pumped at high pressure through the hole and directed to the cutting edges. The coolant serves multiple crucial purposes. It cools the drill and the workpiece, preventing overheating and maintaining the integrity of the Iscar inserts. It also lubricates the cutting process, reducing friction and improving chip evacuation. The high-pressure coolant helps to flush the chips out of the hole, preventing chip clogging, which is a common challenge in deep hole drilling. The flute design of the drill is optimized to work in conjunction with the coolant system, ensuring a smooth and continuous flow of chips. The long length and rigidity of the drill enable it to create deep holes with excellent straightness and dimensional accuracy.
• The deep hole processing capability of these tools makes them indispensable in industries such as aerospace, automotive, and machinery manufacturing, where deep and precise holes are often required for critical components.

Precision Engineering

• Our three sides index Iscar insert drills are manufactured with a high level of precision. The overall design of the drill, including the shank, body, and the attachment of the inserts, is meticulously engineered. 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 inserts during drilling. The surface finish of the drill is carefully 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. Advanced manufacturing techniques and quality control processes are employed to ensure that each drill meets the strictest standards of precision and performance.
• The precision engineering of these drills results in high-quality holes with excellent surface finishes, reducing the need for secondary finishing operations and enhancing the overall productivity of 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, 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 Iscar 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.
