This 10-piece CAT40 lot pairs ER collet chucks with end mill holders, covering the two most frequently used toolholder types on any CAT40 machining center. ER collet chucks handle a wide range of shank sizes with minimal runout, while end mill holders provide a direct, high-rigidity clamp for weldon-shank end mills in heavy cutting applications. Together, ER and end mill holders complement each other — ER chucks excel in lighter, higher-speed work, while end mill holders are the preferred choice when torque and pull-out resistance are the priority, making this mixed lot versatile enough for nearly any shop environment.
