Collis Tool 72427 Split Sleeve Tapping Driver MT2

Product Description

The COLLIS TOOL 72427 is a split sleeve tapping driver designed for use with a 5/8 inch tap on a Morse Taper 2 (MT2) taper shank spindle. The driver accepts a tap shank diameter of 0.48 inches and a tap shank square of 0.36 inches, providing a secure, positive drive during tapping operations. The tap entry depth measures 1-29/64 inches with a 1/4 inch projection. Split sleeve drivers are standard tooling on drill presses, lathes, and CNC machines where controlled tapping torque and tap protection are required. Machinists and toolroom technicians rely on this style of driver to protect taps from breakage by releasing under overload conditions.

This tapping driver is suited for production and maintenance machining environments where 5/8 inch taps are run on MT2-spindle machines. Typical applications include threading operations on drill presses and milling machines equipped with MT2 spindles. The split sleeve mechanism provides automatic torque release, making it appropriate for both through-hole and blind-hole tapping in metal, plastic, and composite materials. It is used by machinists in manufacturing, toolroom, and repair shop settings.

Key Features

• MT2 taper shank mounts directly to standard MT2 spindles without an adapter
• Split sleeve design releases automatically under overload to protect the tap from breakage
• Accepts 5/8 inch taps with a 0.48 inch shank diameter and 0.36 inch shank square
• 1-29/64 inch tap entry depth accommodates standard 5/8 inch tap geometry
• 1/4 inch projection positions the tap correctly relative to the spindle face
• Lightweight at 0.3 pounds for easy handling and quick changeover

Compatibility

Designed as an OEM-style replacement and standard tooling fitment for MT2 taper shank spindle machines accepting 5/8 inch taps with a 0.48 inch shank diameter and 0.36 inch shank square.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the MT2 taper shank. Clean the spindle taper and driver taper with a lint-free cloth before seating to ensure full contact and prevent slippage. Do not use the driver beyond its rated tap size, as doing so can damage the split sleeve mechanism.
