Collis Tool 72505 MT2 Center Drill Driver 7/16 Inch

Product Description

The COLLIS TOOL 72505 is an MT2 outside Morse taper center drill driver designed to hold and drive center drills in machine tool applications. This driver accepts a 7/16 inch center drill body diameter and provides a 1/4 inch projection, giving the tool the reach needed for precise center drilling operations. Compatible with No. 5 and No. 15 center drills, it features an MT2 taper shank for direct mounting into compatible machine tool spindles. The drill tang compatible designation is No, meaning this driver seats and drives through the taper interface alone. Machinists and tool room technicians rely on this style of driver for accurate center hole location on lathes and mills.

This center drill driver is suited for use in machine shops, tool rooms, and production environments where center drilling is a standard step in workpiece preparation. The MT2 taper shank fits a broad range of benchtop and floor-standing lathes, knee mills, and drill presses equipped with MT2 spindle bores. It is used when mounting center drills directly into the spindle without a separate chuck, improving rigidity and concentricity during the operation.

Installation Notes

Installation is performed by machinists or tool room technicians. Before mounting, power down and lock out the machine spindle per standard lockout/tagout procedures. Clean both the driver taper and the spindle bore thoroughly before seating to ensure full taper contact and concentricity. Use a proper drift and drift slot to remove the driver from the spindle - never strike the driver or workpiece directly to dislodge it.
