Addison M2 Long Series Parallel Shank Twist Drill (Size 5.16-8 mm)

Addison M2 Long Series Parallel Shank Twist Drill (Size 5.16-8 mm) Parallel shank twist drill is a precision-engineered cutting tool commonly used in machining operations to create holes in various materials such as metal, wood, plastic, and composites. This type of drill features a straight, cylindrical shank that maintains a consistent diameter throughout its length, enabling it to be securely held in a drill chuck or collet.

The drill bit itself consists of a spiral-shaped cutting edge that extends from the tip to the shank. This helical design facilitates efficient chip removal and enhances cutting performance. The twist angle of the flutes may vary depending on the intended application and material being drilled.

Parallel shank twist drills are available in a wide range of diameters, lengths, and materials to suit different drilling requirements. High-speed steel (HSS) is a common material for general-purpose drilling, while carbide or cobalt variants offer increased durability and heat resistance for more demanding applications.

These drills are compatible with various drilling machines, including hand drills, drill presses, and CNC machining centers, making them versatile tools in manufacturing, construction, maintenance, and repair tasks.

Overall, the parallel shank twist drill is an essential tool in the arsenal of any machinist or craftsman, providing precision, reliability, and efficiency in hole-making operations.
