Rail drill bits are a high-efficiency cutting tool specifically designed for the construction and maintenance of railways and rail transit systems, as well as for the production of special equipment. They perform excellently in drilling rails of grades U74, U71MN, PD2, PD3 (U75V), and others; Chuangheng Company is a pioneer in the production of high-speed steel rail drill bits and is distinguished by the following key characteristics:
1. By material and design, rail drills are divided into four main categories: carbide drills, high-speed steel drills, solid steel drills, and drills with replaceable cutting edges;
2. Carbide drills and high-speed steel drills, depending on their performance characteristics, are divided into standard and high-performance series;
3. High-speed steel drills are suitable for dry cutting, while carbide drills are used for processing materials of high hardness.
