Straight Shank Drill Chuck Arbors – Partially Ground
Straight shank drill chuck arbors with a partially ground shank provide a practical balance between accuracy and versatility for general drilling applications. These arbors are designed to mount into collet chucks, end mill holders, or other straight-shank toolholding systems while maintaining reliable alignment between the spindle and drill chuck.
Commonly used in CNC machines, milling machines, and job shop environments, partially ground straight shank arbors offer consistent performance at a lower cost than fully ground alternatives. They are well suited for everyday drilling operations where dependable concentricity and durability are required.
