+91-8777212335

Short Description

Certain drilling applications require greater reach than standard or long series drills can provide. Extra Long Series Drill Bits are designed for machining deep holes in components where extended tool length is essential. Featuring a longer flute and overall body, these drills allow access to hard-to-reach areas while maintaining reliable cutting performance and efficient chip evacuation. They are widely used in heavy engineering, fabrication, automotive, mould making, maintenance, and general machining applications where precision and extended drilling depth are equally important.
