Long Series Drills

A long series drill, also known as an extended-length drill bit, is a type of drill bit designed to reach deeper into materials than standard-length drill bits. These drills are typically used when the material being drilled is thick or when you need to reach a deeper spot without enlarging the hole.

Purpose and Function Long Series Drills:

• Deep Drilling: Long series drills are primarily used for drilling deeper holes where a standard drill bit might not reach. They're commonly used in applications requiring holes to be drilled through thick materials like metal, wood, or plastic.
• Precision: These drills are designed to maintain accuracy and precision even at greater depths, minimizing the risk of hole deviation.
• Extended Reach: Ideal for applications where you need to reach into confined or difficult-to-access areas, making them indispensable in various industrial and construction settings.

Types of Long Series Drills:

• High-Speed Steel (HSS): These are versatile and suitable for drilling into a wide range of materials, including metals, plastics, and wood.
• Cobalt Drills: Made with a cobalt alloy, these drills are more heat-resistant and are ideal for drilling harder materials like stainless steel.
• Carbide-Tipped Drills: These are used for extremely hard materials, providing longer life and better performance in tough conditions.

Applications

• Automotive Industry: Used for deep drilling in engine blocks, crankshafts, and other thick components.
• Construction: Essential for creating deep anchor points in beams or walls.
• Metalworking: Used for boring deep holes in thick metal parts and machinery components..
• Aerospace: Employed in the manufacturing and maintenance of aircraft parts that require precise and deep drilling.

Advantages

• Extended Reach: The longer length of these drills allows for deeper holes to be drilled, which is essential in applications requiring access to hard-to-reach areas or when drilling through thick materials.
Versatility: HSS material is known for its toughness and ability to withstand high temperatures, making these drills suitable for a wide range of materials, including steel, aluminum, and plastic.
• Durability:HSS drills maintain their hardness at high temperatures, reducing wear and extending the tool's life, which is particularly useful when drilling tough materials.
• Precision: The long series design helps maintain alignment and accuracy over greater depths, reducing the likelihood of the drill wandering off course.
• Cost-Effective: Compared to carbide drills, HSS long series drills offer a good balance of performance and cost, making them an economical choice for many applications.
• Resharpening: HSS drills can be resharpened multiple times, which extends their usability and reduces overall tooling costs.
