Collis Tool 70507 Standard Tapping Driver MT5 Taper Shank

Product Description

The COLLIS TOOL 70507 is a standard tapping driver designed for use with a 2-1/4 inch tap in machine tool and manual tapping operations. It features an MT5 taper shank for secure mounting in compatible spindles and a tap entry depth of 3.13 inches, making it suitable for deep-hole and production tapping applications. The driver projects 4-5/16 inches from the shank reference point and accepts a tap shank diameter of 1.894 inches with a tap shank square of 1.42 inches. At 9.05 pounds, this is a robust, production-grade tool intended for machinists and tool-room professionals working on medium to large tapping operations.

This tapping driver is used in machine shop environments where an MT5 taper spindle interface is present, such as drill presses, milling machines, and lathes equipped with Morse Taper 5 spindles. It is suited for industrial production tapping and tool-room work where a 2-1/4 inch tap must be driven with controlled, consistent torque transmission. The standard tapping driver configuration is a common fit for facilities running high-volume or precision threading operations on ferrous and non-ferrous materials.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Before mounting, ensure the machine spindle and MT5 taper bore are clean and free of burrs or debris to achieve full taper contact. Power down and lock out the machine before inserting or removing the tapping driver from the spindle. Verify tap shank dimensions match driver specifications before assembly to prevent drive slippage during operation.
