Parallel Shank Twist Drills - Stub Series

+91-8777212335

Short Description

Not every drilling application requires a long drill. In many machining operations, a shorter tool offers greater stability and improved accuracy. A stub drill is designed with a reduced flute length and overall length, making it more rigid than standard twist drills. This compact design minimises tool deflection and vibration, resulting in better hole accuracy and longer tool life. Stub drill bits are widely used for precision drilling in steel, cast iron, aluminium, non-ferrous metals, and engineering plastics, making them a preferred choice for machine shops, automotive manufacturing, tool rooms, fabrication units, and general engineering applications.
