This 10-piece CAT40 lot combines end mill holders and face mill arbors, targeting two of the highest-torque operations on a machining center. End mill holders use a set screw against the weldon flat to deliver direct, pull-out-resistant clamping, while face mill arbors support the large-diameter face mills used for high-material-removal surfacing operations. Compared to collet-based holder lots, a set built around end mill holders and face mill arbors is oriented toward power milling rather than versatility — the right choice for shops with defined processes involving heavy end milling, roughing, and surface milling where tool pull-out or runout under load is a concern.
