Collis Tool 73422 Split Sleeve Tapping Driver MT3

Product Description

The COLLIS TOOL 73422 is a split sleeve tapping driver with an MT3 taper shank, designed to hold and drive taps in machining and drilling operations. It accepts a 5/8 inch tap with a tap entry depth of 1-29/64 inches and provides 1/4 inch projection. The tap shank diameter is 0.48 inches and the tap shank square measures 0.36 inches. This driver is used in production and toolroom environments where accurate, repeatable tapping is required on drill presses, milling machines, and similar machine tools. Machinists and toolroom technicians are the primary users of this type of toolholder.

The 73422 is suited for use in metal-cutting operations on drill presses and vertical milling machines where a floating or driven tapping attachment is needed. The MT3 taper shank seats directly into compatible spindle tapers, providing a secure, repeatable connection for tapping ferrous and non-ferrous materials. The split sleeve design allows the driver to grip the tap shank securely while allowing quick tap changes. Typical applications include production tapping in job shops, toolrooms, and general metalworking facilities.
