Value Collection SC00186353 MT3 to MT5 Morse Taper Adapter

Product Description

The VALUE COLLECTION SC00186353 is a Morse taper extension adapter designed to bridge an MT3 inside taper to an MT5 outside taper. It extends reach in drilling and boring setups where the spindle taper is larger than the tooling shank. The adapter measures 10.5 inches overall length (OAL) and is constructed from medium carbon steel with a soft body and hardened tang. The hardened tang resists the drive forces of the spindle drift key, while the soft body allows the tapers to seat cleanly without galling the mating surfaces. Machinists and machine tool technicians install this adapter in drill press, lathe, and milling machine applications.

This adapter is suited for machine shop environments where MT5 spindles must accept MT3 tooling, such as drill chucks, boring heads, or center sleeves. The 10.5-inch OAL provides added reach for deep-hole operations or setups requiring extended tool projection. It is appropriate for both production and maintenance machining applications in industrial and toolroom settings.

Key Features

• MT3 inside taper accepts standard MT3 tooling shanks
• MT5 outside taper seats directly into MT5 machine spindles
• 10.5 inches OAL for extended reach in deep-hole and offset setups
• Medium carbon steel construction for strength and machinability
• Hardened tang withstands drift-key ejection forces
• Soft taper body promotes accurate seating without surface damage

Compatibility

Designed as a standard Morse taper extension adapter for machine tools equipped with an MT5 spindle bore requiring MT3 tooling fitment.

Installation Notes

Installation is performed by qualified machinists or machine tool technicians. Power down and lock out the machine before inserting or removing any taper adapter. Clean all taper surfaces and remove any burrs or debris before seating the adapter to ensure full contact and accurate alignment. Remove the adapter using a drift key through the spindle slot; do not strike the tooling directly.
