Product Description

The COLLIS TOOL 70509 is a standard tapping driver designed for use with MT5 taper shank machine tool spindles. It accepts a 2.5-inch tap and provides a tap entry depth of 3.5 inches, making it suitable for deep-hole or production tapping operations. The driver features a 4.625-inch projection and a tap shank diameter of 2.1 inches, with a tap shank square of 1.575 inches. Weighing 11.17 pounds, this is a heavy-duty tooling component installed by machinists and toolroom professionals on milling machines, drill presses, or tapping centers.

This tapping driver is intended for industrial and production machine shop environments where consistent, repeatable tapping performance is required. The MT5 taper shank provides a rigid, self-holding connection to compatible machine spindles. It is well-suited for applications demanding accurate thread formation in metal workpieces using standard tap geometries. Installation and setup are performed by skilled machinists or toolroom technicians as part of a tooling changeover or new setup on compatible equipment.
