Collis Tool 71320 Split Sleeve Tapping Driver MT1

Product Description

The COLLIS TOOL 71320 is a split sleeve tapping driver designed for use with a 1/4 inch tap and an MT1 Morse taper shank. It provides a 31/32 inch tap entry depth and a 3/16 inch projection, making it suitable for precision tapping operations in machining and metalworking environments. The tap shank diameter measures 0.255 inches and the tap shank square measures 0.191 inches. This driver is installed by machinists, toolroom technicians, and trade professionals who require a reliable, positive-drive connection between a taper shank spindle and a standard tap during through-hole or blind-hole tapping work.

The COLLIS TOOL 71320 is suited for use in drill press, milling machine, and lathe tailstock applications where an MT1 taper shank socket is present. It is a common choice for light-duty tapping operations on ferrous and non-ferrous materials in job shop, maintenance, and production machining settings. The split sleeve design allows quick tap changes without removing the driver from the spindle, improving workflow efficiency in repetitive tapping tasks.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with Morse taper tooling. Ensure the machine spindle is fully powered down and at a complete stop before inserting or removing the driver. Clean both the MT1 taper shank and the spindle socket before seating to ensure full taper engagement and prevent fretting. Verify tap shank dimensions match driver specifications before use to avoid slippage or driver damage.
