Collis Tool 71159 MT1 Morse Taper Drill Driver

Product Description

The COLLIS TOOL 71159 is an MT1 outside Morse taper drill driver designed to seat and drive taper-shank drill bits in compatible spindles and chucks. With a 3/16 inch projection and a drill tang thickness range of 0.09 to 3/32 inch, it provides a secure mechanical interface between the drill bit tang and the driving spindle. Rated for a drill size of 0.1496 inch decimal and a drill depth of 3/4 inch, this driver is built for precision drilling applications where consistent taper engagement is required. It is used by machinists, tool-and-die professionals, and maintenance technicians working with taper-shank tooling setups.

This drill driver is suited for machine shop, production, and maintenance environments where MT1 taper-shank tooling is standard. It accommodates drill bits with a compatible tang, allowing the spindle to positively drive the bit without relying solely on friction. Typical install scenarios include drill presses, milling machines, and lathe tailstocks configured for Morse taper tooling. The 3/4 inch drill depth and 0.1496 inch drill size designation make it appropriate for light-duty precision drilling operations at this size range.

Compatibility

Designed as an OEM-style replacement or direct-fit driver for MT1 Morse taper spindle applications requiring tang-drive engagement with taper-shank drill bits in the 0.1496 inch size range.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician. Always power down and lock out the machine before seating or removing any taper tooling from the spindle. Ensure the taper bore and driver shank are clean and free of debris before seating to prevent fretting or misalignment. A proper drift and drift slot should be used to remove the driver from the spindle; never strike the tooling directly.
