Value Collection SC00186338 MT3 Morse Taper Extension Adapter

Product Description

The VALUE COLLECTION SC00186338 is a Morse taper extension adapter designed to extend or connect MT3 tooling in machine tool applications. It accepts an MT3 inside taper and presents an MT3 outside taper, allowing a technician to extend reach or adapt between compatible spindles and tool shanks. The body is medium carbon steel with a soft construction and hardened tang, providing wear resistance at the drive point while keeping the body machinable if needed. Overall length is 8.5 inches. This adapter is a direct-fit solution for lathes, drill presses, and milling machines that use the MT3 standard taper system.

This adapter is suited for machine shops, tool rooms, and maintenance facilities where MT3 tooling must be extended or repositioned within a spindle. Typical applications include extending drill chucks, live centers, or arbors in lathe tailstocks and drill press spindles. The MT3-to-MT3 configuration makes it a straightforward swap when additional clearance or reach is required without changing the taper standard. Installation is handled by machinists and tool-and-die technicians during setup or tooling changeovers.

Key Features

• MT3 inside taper accepts standard MT3 tooling shanks
• MT3 outside taper fits MT3 spindle sockets directly
• 8.5 inch overall length provides extended reach for deep-reach applications
• Medium carbon steel construction balances strength and machinability
• Hardened tang resists wear and drive-slot damage during installation and removal
• Soft body allows re-machining or cleanup if required

Compatibility

Designed as a standard MT3-to-MT3 extension adapter compatible with machine tool spindles and tooling holders that conform to the Morse Taper 3 standard, including lathe tailstocks, drill press spindles, and milling machine quills using MT3 sockets.

Installation Notes

Installation and removal should be performed by a qualified machinist or tool-and-die technician. Ensure the machine is fully powered down and the spindle is locked before inserting or drifting the adapter. Use a proper drift punch against the hardened tang to remove the adapter without damaging the taper bore. Inspect both the inside and outside taper surfaces for burrs or debris before seating to ensure full contact and concentricity.
