Ten CAT40 ER collet chuck holders in a single lot — a clean, ready-to-use set that covers the most common toolholder need on any CAT40 machining center. ER collet holders are preferred for their low runout, broad shank-size compatibility within each ER collet size, and fast tool changeover without the torque wrench precision required by side-lock or set-screw holders. For shops running high-mix work or frequent job changes, having a dedicated set of 10 ER collet holders allows tools to stay pre-loaded between jobs — eliminating the time lost pulling and re-setting tools in shared holders between operations or setups.
