Collis Tool 75101 Split Sleeve Tapping Driver MT5

Product Description

The COLLIS TOOL 75101 is a split sleeve tapping driver designed for use with MT5 taper shank machine tool spindles. It accepts a 1-1/4 inch tap and provides a tap entry depth of 2-19/64 inches, making it suitable for deep-hole tapping operations on larger machining centers, drill presses, and turret lathes. The driver features a split sleeve design that allows the tap to float axially and angularly, reducing tap breakage and thread damage. A 7/16 inch projection and a tap shank diameter of 1.021 inches position this driver for heavy-duty industrial tapping work. The unit weighs 2.6 pounds and is sold as a single piece.

This tapping driver is intended for use in machine shop and manufacturing environments where precise, controlled tapping is required in ferrous and non-ferrous materials. It is installed by skilled machinists and toolroom technicians. The MT5 taper shank fits directly into compatible machine spindles without an adapter in most standard applications. Typical use cases include production tapping on knee mills, radial arm drills, and CNC machining centers equipped with MT5 spindle receivers.

Installation Notes

Installation and setup should be performed by a qualified machinist or toolroom technician. Before mounting or removing the driver, ensure the machine spindle is fully powered down and the spindle is locked or secured per the machine manufacturer's procedure. Clean both the MT5 taper shank and the spindle socket thoroughly before seating to ensure full contact and prevent fretting. Confirm tap shank diameter and square dimensions match the driver before assembly to avoid damage to the tap or the sleeve.
