Rail Twist Drill Bit

A Railway Twist Drill Bit with Straight Shank is a specialized cutting tool designed for drilling precise holes in steel rails, commonly used in railway maintenance and infrastructure projects. These drill bits are essential for tasks such as installing joint bars, grounding cables, and mounting signaling equipment.

Key Features

• Material Composition: Typically constructed from High-Speed Steel (HSS) for durability and heat resistance. Some variants feature carbide tips for enhanced cutting performance in hard rail materials.

• Shank Design: Straight shank design allows for secure clamping in standard drill chucks, ensuring stability during operation.

• Point Geometry: Often equipped with a notched or split point to facilitate easy centering and reduce walking on the curved surface of rails.

• Surface Treatment: Many bits undergo surface treatments, such as nitriding, to increase wear resistance and extend tool life.

• Size Variations: Available in various diameters and lengths to accommodate different drilling requirements in rail applications.

Product Specifications

Material: HSS

Diameter: 9.8-13.5mm

Cutting depth: 25mm

It is applicable to all kinds of internal combustion and electric rail drill machine, railway maintenance and repair, rail drilling operations.

The drill bit is a short cylindrical positioning drill. As a result it can easily match with the drilling machine, but also eliminates the repeated replacement of the chuck, and enhance its tightening force so as to maintain a strong power. Its efficiency is higher than the ordinary twist drill and having water-drainage holes for cooling on the shank, it is a good tool for electrical maintenance work.

Advantages

• Precision: Designed to produce clean, accurate holes in high-strength rail materials.

• Durability: High-quality materials and surface treatments contribute to a longer service life, even under demanding conditions.

• Compatibility: Straight shank design ensures compatibility with a wide range of drilling equipment used in railway operations.
