Collis Tool 60722 Morse Taper Extension MT2 9-3/16 in

Product Description

The COLLIS TOOL 60722 is a Morse taper extension socket that accepts an MT2 inside taper and presents an MT2 outside taper, extending the reach of tooling in lathe tailstocks, drill presses, and milling machine spindles. With an overall length of 9-3/16 inches, this extension adds clearance between the spindle nose and the workpiece without requiring a change in tooling size. The body is machined from steel for rigidity under cutting loads. Machinists, toolroom operators, and maintenance technicians install this type of adapter when standard taper depth is insufficient for deep-hole drilling, long boring operations, or similar setups.

The 60722 is suited for machine shop and industrial maintenance environments where MT2 tooling is standard. Typical applications include extending drill chuck reach in tailstock operations, adding clearance for long-series drills, and accommodating workpiece geometry that positions the spindle farther from the cutting zone than standard taper-to-taper engagement allows. The steel construction holds up to the lateral and axial forces common in production drilling and reaming operations.

Key Features

• MT2 inside taper accepts standard MT2 shanks without an adapter
• MT2 outside taper seats directly in MT2-compatible spindles and tailstocks
• 9-3/16 inch overall length provides meaningful reach extension over standard sockets
• Steel construction resists deflection under drilling and reaming loads
• Taper-to-taper design maintains centerline alignment between spindle and tooling

Compatibility

Designed as an OEM-style extension for machine spindles and tailstocks with an MT2 bore, accepting MT2-shank tooling such as drill chucks, drill sleeves, and boring heads.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine before seating or removing any taper tooling. Clean both the spindle bore and the extension taper surfaces before installation to ensure full seating and accurate alignment. Remove the extension using a drift pin through the spindle drift slot rather than striking the tooling directly.
