Value Collection SC00186551 MT5 Morse Taper Extension Adapter

Product Description

The VALUE COLLECTION SC00186551 is an MT5-to-MT5 Morse taper extension adapter used to extend the reach of drill press spindles, milling machine quills, and lathe tailstocks when additional tooling clearance is required. It accepts an MT5 inside taper and presents an MT5 outside taper, allowing standard MT5 shank tooling to seat securely at an extended depth. The body is constructed from medium carbon steel with a soft body and a hardened tang for durability at the drive point. Overall length is 13.25 inches. This adapter is suited for machine shops, maintenance facilities, and metalworking operations where spindle extension is a routine requirement.

This extension adapter is installed in machine tool spindles rated for MT5 tooling where additional clearance between the spindle nose and the workpiece is needed. Typical applications include deep-hole drilling setups, extended boring operations, and situations where a standard-length arbor or chuck shank cannot reach the work envelope. The hardened tang engages the spindle drift slot for positive retention and controlled removal. It is appropriate for use on heavy-duty drill presses, knee mills, and engine lathes with MT5 spindle bores.

Key Features

• MT5 inside taper accepts standard MT5 shank tooling such as drill chucks and arbors
• MT5 outside taper seats directly into MT5 spindle bores without adapters
• 13.25-inch overall length provides significant spindle extension for deep-clearance applications
• Medium carbon steel body balances machinability with structural rigidity
• Hardened tang resists deformation during drift-key removal
• Soft body allows re-grinding or refacing if the taper surface wears over time

Compatibility

Designed for use with machine tools equipped with MT5 spindle bores requiring a Morse taper to Morse taper extension configuration. Specific compatible machine models were not identified in the available product data.

Installation Notes

Installation and removal should be performed by a qualified machinist or maintenance technician familiar with Morse taper tooling. Power off and lock out the machine at the main disconnect before inserting or removing any taper tooling. Clean both the spindle bore and the adapter taper surfaces thoroughly before seating to ensure full contact and prevent taper slippage under load. Use a proper drift key through the spindle slot to remove the adapter — never hammer directly on the tooling body.
