Value Collection 220-1532 Boring Head Taper Shank MT3

Product Description

The VALUE COLLECTION 220-1532 is a Morse Taper 3 (MT3) boring head shank designed to connect a boring head to a milling machine or boring mill spindle using a threaded interface. The shank seats directly into an MT3-compatible spindle and threads into the boring head body via a 7/8-20 threaded mount. Weighing 1.48 pounds, this is a solid, purpose-built adapter component used in metal-removal operations where precise bore sizing is required. Machinists and toolroom technicians install this shank as part of a complete boring head assembly on manual or CNC knee mills and vertical machining centers with MT3 spindles.

This shank is suited for shop environments running MT3-spindle machines that require a threaded boring head connection. Typical applications include line boring, precision bore finishing, and diameter sizing on ferrous and non-ferrous workpieces. It is not configured for coolant-through delivery, making it appropriate for dry or flood-coolant setups where coolant is directed externally. The 7/8-20 thread size is a common standard for boring head body attachment across a range of boring head diameters.

Key Features

• MT3 taper shank seats directly into standard Morse Taper 3 spindles without adapters
• 7/8-20 threaded mount provides secure, repeatable connection to compatible boring head bodies
• No coolant-through design simplifies setup in conventional flood or dry machining environments
• Compact, 1.48-pound construction reduces spindle load during boring operations
• Single-piece shank construction for rigid tool holding and minimal runout

Compatibility

Designed for use with boring heads featuring a 7/8-20 threaded mount on machines equipped with an MT3-compatible spindle. No specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing the taper shank. Clean the MT3 taper bore and shank surface thoroughly before insertion to ensure full contact and minimize runout. Use the appropriate drawbar or retention hardware as required by the machine spindle design to secure the taper during operation.
