Value Collection SC00187245 MT2 to MT4 Morse Taper Extension

Product Description

The VALUE COLLECTION SC00187245 is a Morse taper extension adapter designed to connect a MT2 inside taper to a MT4 outside taper, extending tool reach in lathe, drill press, and milling machine spindles. The adapter measures 8.5 inches overall length and is manufactured from medium carbon steel that has been hardened and ground throughout for dimensional accuracy and long service life. Machinists and toolroom technicians use this style of adapter when a tool shank is smaller than the machine spindle taper, allowing the correct seating force to be transmitted without regrinding or switching spindles.

This adapter fits horizontal and vertical machining setups where an MT2 tool or arbor must seat in an MT4 spindle. Typical applications include drill presses, engine lathes, milling machines, and boring machines operating with standard Morse taper tooling. The 8.5-inch OAL provides extended reach that is useful when working in deep bores or when additional clearance is needed between the spindle nose and the workpiece. Installation and removal follow standard Morse taper drift practices and require no special modifications to the machine spindle.

Key Features

• MT2 inside taper accepts MT2 tooling directly into the adapter socket
• MT4 outside taper seats into any standard MT4 machine spindle
• 8.5 inches overall length provides extended tool reach
• Medium carbon steel construction with hardened and ground finish throughout
• Ground tapers ensure accurate tool alignment and positive drive

Compatibility

Designed as a standard OEM-style Morse taper extension adapter for use in machine tool spindles accepting an MT4 outside taper with MT2 inside tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before inserting or removing the adapter. Clean both the spindle bore and the adapter taper surfaces thoroughly before seating to ensure full contact and prevent fretting. Use a proper Morse taper drift bar through the spindle drift slot to remove the adapter; never use an impact tool against the taper body.
