Collis Tool 70410 Tapping Driver MT4 Taper Shank

Product Description

The COLLIS TOOL 70410 is a standard tapping driver designed for use with an MT4 taper shank interface. It accepts a 1.875-inch tap with a tap entry depth of 2.5 inches and a projection of 3.25 inches, making it suited for deep-reach tapping operations on drilling machines and machining centers. The tap shank diameter measures 1.519 inches with a tap shank square of 1.139 inches, providing positive drive engagement during threading operations. At 4.1 pounds, this driver is built for rigid tapping setups where consistent torque transmission and shank alignment are critical. Machinists and toolroom technicians working on production or maintenance tapping jobs will find this driver compatible with standard MT4-equipped equipment.

This tapping driver is used in machine shop environments, including production facilities, maintenance shops, and toolroom operations. It is intended for use on drill presses, milling machines, and machining centers equipped with an MT4 spindle taper. The 2.5-inch entry depth supports tapping operations that require the tap to reach into deeper bores or stepped features without interference from the driver body.

Installation Notes

Installation should be performed by a qualified machinist familiar with taper shank tooling. Power down and lock out the machine spindle before inserting or removing the driver. Ensure the MT4 taper bore is clean and free of debris before seating the shank to prevent runout or slippage during operation. Follow the machine manufacturer guidelines for drawbar engagement where applicable.
