Value Collection 220-1554 Boring Head MT5 Taper Shank

Product Description

The VALUE COLLECTION 220-1554 is a Morse Taper 5 (MT5) boring head taper shank with a 1-1/2-18 threaded mount, designed to connect a boring head to a compatible machine spindle on milling machines and boring mills. The MT5 taper provides a rigid, self-holding connection to the spindle, while the 1-1/2-18 threaded nose interfaces directly with the boring head body. Weighing 4.6 pounds, this shank is built for applications where rigidity and concentricity are critical to achieving accurate bore diameters. Coolant-through capability is not included in this configuration. Machinists and tool-and-die professionals use this shank as a core component of a precision boring setup.

This taper shank is suited for use in manual and CNC milling machines or horizontal boring mills equipped with an MT5 spindle. It is typically used in machine shops, tool rooms, and production environments where off-center boring or precise diameter work is performed. The 1-1/2-18 threaded mount accepts standard boring head bodies that use this thread specification. It is appropriate for both roughing and finishing boring operations when paired with the correct boring head and insert tooling.

Key Features

• MT5 (Morse Taper 5) shank provides a self-holding fit in compatible machine spindles
• 1-1/2-18 threaded mount interfaces with standard boring head bodies
• No coolant-through ports — suited for dry or flood coolant environments where through-tool coolant is not required
• 4.6-pound construction reflects a robust, solid shank build for rigidity during boring operations
• UNSPSC Code 27112800 for procurement and catalog classification

Compatibility

Designed for use with boring head bodies that accept a 1-1/2-18 threaded mount connection, installed in machine spindles with an MT5 taper socket. Consult your boring head and machine tool specifications to confirm thread and taper compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with Morse Taper tooling and machine tool setup procedures. Before installing or removing the shank, ensure the machine is fully powered down and the spindle is locked or secured per the machine manufacturer's guidelines. Clean both the MT5 shank and spindle bore thoroughly to remove chips, oil film, and debris before seating, as contamination will affect runout and concentricity. Use a drawbar if the machine spindle is designed to accept one, and follow standard shop practices for taper seating and removal to avoid damage to the taper surfaces.
