Collis Tool 72292 Letter L MT2 Drill Driver

Product Description

The COLLIS TOOL 72292 is a Letter L drill driver with an MT2 outside Morse taper shank, designed to securely seat and drive letter-size drill bits in machine tool spindles. The driver features a 1/4 inch projection and accepts drill tang thicknesses from 0.158 to 0.162 inches, providing positive drive engagement and reducing spindle slip under cutting loads. With a decimal inch drill size of 0.2900 and a drill depth of 1 inch, this driver suits precision drilling operations in metal fabrication, machining, and maintenance applications. It is installed by machinists and tool-room technicians working with drill presses, lathes, and milling machines equipped with MT2 spindle tapers.

This drill driver is suited for shop-floor and production drilling environments where letter-size tooling is run through Morse taper spindles. The MT2 taper is a common interface found on a wide range of benchtop and floor-standing drill presses as well as lathe tailstocks. It is appropriate for both light production runs and maintenance drilling tasks where repeatable tool seating and positive tang drive are required.

Installation Notes

Installation is performed by qualified machinists or tool-room personnel. Power down and lock out the machine spindle before seating or removing the taper driver. Clean both the spindle bore and the MT2 taper shank thoroughly before insertion to ensure full contact and accurate seating. Never strike the driver into the spindle with excessive force; use a proper draw bar or drift key removal procedure to avoid damaging the taper surfaces.
