Collis Tool 70505 Standard Tapping Driver MT5 Taper Shank

Product Description

The COLLIS TOOL 70505 is a standard tapping driver designed to securely hold and drive taps during machining operations. Featuring an MT5 taper shank, this driver mounts directly into compatible machine spindles and transmits torque to the tap with a positive drive. The 2-inch tap capacity handles heavy-duty tapping work, and the 2.63-inch tap entry depth accommodates a range of tap lengths. The 3.75-inch projection positions the tap at a practical working distance from the spindle face. With a tap shank diameter of 1.644 inches and a tap shank square of 1.233 inches, this driver is dimensioned for large, production-grade tapping applications. Machinist and toolroom technicians are the primary installers.

This tapping driver is suited for use on vertical mills, drill presses, radial arm drills, and similar machine tools equipped with an MT5 spindle taper. It is appropriate for production and job-shop environments where consistent, repeatable tap alignment is required. The large tap capacity makes it a fit for tapping operations in heavy steel, cast iron, and other ferrous materials where torque loads are significant. It is not intended for hand tapping or portable drill use.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the driver. Clean the MT5 taper bore and the driver shank thoroughly before seating to ensure full contact and accurate alignment. Do not force the taper shank with impact tools, as this can damage the taper interface or the spindle bore.
