Value Collection SC00187336 MT3 to MT3 Taper Extension Adapter

Product Description

The VALUE COLLECTION SC00187336 is a Morse taper extension adapter designed to extend the spindle reach of machine tools that use Morse taper tooling. It accepts an MT3 inside taper and presents an MT3 outside taper, allowing a technician or machinist to add length between the spindle and the cutting tool or chuck without changing the taper size. The adapter measures 8.5 inches overall length and is constructed from medium carbon steel that has been hardened and ground throughout, providing consistent taper geometry and reliable tool holding under load.

This adapter is used in machine shop and maintenance environments where a drill press, lathe, milling machine, or similar machine tool requires extended reach to access a workpiece or fixture. It is a same-size MT3-to-MT3 extension, meaning the taper size does not change from input to output. Typical applications include production machining, toolroom work, and industrial maintenance operations where standard spindle depth is insufficient for the job at hand.

Key Features

• MT3 inside taper accepts standard MT3 tooling or shanks
• MT3 outside taper fits directly into any MT3 spindle or holder
• 8.5 inches overall length provides meaningful spindle extension
• Medium carbon steel construction for strength under axial and radial loads
• Hardened and ground throughout for precise taper fit and long service life

Compatibility

Designed as a same-size MT3-to-MT3 extension for use in any machine tool spindle or holder that accepts a standard Morse Taper 3 shank, including drill presses, lathes, and milling machines equipped with MT3 spindles.

Installation Notes

Installation is performed by machinists or maintenance technicians. Power down and lock out the machine tool before inserting or removing any taper adapter. Clean both the spindle bore and the adapter taper surfaces thoroughly before seating to ensure full contact and prevent fretting. Use a proper drift and mallet to remove the adapter through the spindle drift slot; never attempt to pry a seated taper free from the side.
