Value Collection 220-1534 Boring Head MT3 Taper Shank

Product Description

The VALUE COLLECTION 220-1534 is a boring head taper shank designed to connect a boring head to a machine spindle using a Morse Taper 3 (MT3) shank and a 1-1/2-18 threaded mount interface. The MT3 taper provides a self-holding fit in compatible spindles, while the threaded mount allows secure attachment to a standard boring head body. This component is used in manual milling machines and drill presses where precision boring operations are required. Installation is typically performed by machinists and tool-and-die professionals working in job shop, maintenance, or production environments.

This taper shank is suited for light-to-medium boring operations on manual knee mills, Bridgeport-style machines, and similar equipment equipped with MT3 spindles. It serves as the intermediate adapter between the machine spindle and the boring head assembly. The 1-1/2-18 threaded mount is a common standard interface found on many boring head bodies in this size range. Coolant-through capability is not included in this design.

Compatibility

Designed for use with machine spindles accepting an MT3 taper and boring head bodies with a 1-1/2-18 threaded mount interface. Compatible with manual milling machines and drill presses that use MT3 tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before installing or removing the taper shank. Clean the spindle bore and taper shank surfaces thoroughly before seating to ensure full contact and accurate alignment. Use a draw bar where the spindle design requires it to secure the MT3 taper against pull-out during cutting operations.
