Value Collection SC00185140 MT4 Morse Taper Adapter 6 in

Product Description

The VALUE COLLECTION SC00185140 is a Morse Taper to Straight Shank adapter designed for machine tool applications where an MT4 inside taper is required to interface with a straight shank toolholder or spindle. Constructed from medium carbon steel and hardened and ground throughout, this adapter delivers consistent concentricity and dimensional accuracy under typical drilling, boring, and reaming loads. The overall length is 6 inches, making it suitable for standard quill and spindle setups found in drill presses, lathes, and milling machines. Machinists, tool-and-die workers, and machine shop technicians are the primary installers of this type of adapter.

This adapter fits applications where an MT4 taper bore must accept a straight shank cutting tool or arbor. It is commonly used in production and maintenance machine shops, toolroom environments, and vocational or educational machining programs. The hardened and ground construction makes it appropriate for repeated insertion and removal cycles without significant wear to the taper surfaces. Suitable for both manual and CNC-equipped machines that retain an MT4 spindle or quill bore.

Installation Notes

Installation is performed by qualified machinists or machine tool technicians. Always power down and lock out the machine spindle before inserting or removing the adapter. Clean the taper bore and adapter shank thoroughly before seating to ensure full contact and prevent fretting. Use a proper drift key and soft mallet to remove the adapter — never strike the spindle housing or use excessive force that could damage the taper bore.
