AMG Step Drill with Fixed Shank – High-Precision Multi-Diameter Drilling Solution
The AMG fixed-shank step drill is a multifunctional solid carbide drill specially developed for multi-diameter hole processing, and high-precision drilling. Featuring an integrated step design, it can complete multiple diameter holes in a single feed, significantly improving machining efficiency . This tool is widely used in mechanical processing, mold manufacturing, aerospace components, automotive parts, and electronic equipment.
Manufactured from premium ultra-fine grain carbide, the AMG step drill offers excellent wear resistance and fracture toughness. Combined with high-precision CNC grinding and advanced coating technologies such as TiAlN and DLC, it delivers outstanding stability and cutting performance at high speeds. The fixed shank design ensures stable clamping, making it especially suitable for CNC machining centers and CNC drilling and milling machines.
Applications:
Multi-diameter one-pass drilling
Internal step forming and deburring
Drilling of electronic and electrical equipment housings
Automotive engine housings and mold structural parts
