This 10-piece CAT45 tool holder lot includes ER collet holders, drill holders, and a live center holder, providing a functional foundation for CAT45 taper machining centers. The CAT45 taper is less common than CAT40 but widely found on older Mazak, Mori Seiki, and similar Japanese-built machining centers, making quality used holders like these harder to source than the equivalent CAT40 sizes. Compared to CAT40 lots of similar composition, CAT45 holders are designed for a larger spindle taper with greater clamping force capacity, making them suitable for heavier cuts — while the included live center holder adds versatility for combined mill-turn or specialized boring applications.
