Value Collection 331-2108 Shell Reamer Arbor 3MT Morse Taper

Product Description

The VALUE COLLECTION 331-2108 is a shell reamer arbor designed to mount shell reamers in machine tool spindles using a No. 3 Morse Taper shank. The arbor accepts shell reamers ranging from 1-5/16 inches to 1-5/8 inches in diameter and measures 11 inches in overall length. It serves as the drive interface between the machine spindle and the shell reamer body, transmitting torque and providing precise alignment during reaming operations. Machinists and tool-and-die professionals install this arbor in drill presses, lathes, and milling machines where finish-bore sizing is required.

This arbor is suited for metalworking shops performing precision bore finishing on ferrous and non-ferrous materials. Typical applications include final-sizing bored holes in machine components, fixtures, and production parts where close tolerances are required. The 3MT shank fits spindles commonly found in knee mills, radial arm drill presses, and engine lathes equipped with a No. 3 Morse Taper socket. The 11-inch overall length provides clearance for deep-bore setups and workholding fixtures with extended reach requirements.

Compatibility

Designed as a standard replacement or spare shell reamer arbor for machine tool spindles with a No. 3 Morse Taper socket, compatible with shell reamers measuring 1-5/16 inches to 1-5/8 inches in diameter.

Installation Notes

Installation is performed by qualified machinists. Clean the Morse Taper shank and spindle socket thoroughly before seating to ensure full contact and prevent fretting. Power down and lock out the machine before mounting or removing the arbor. Do not strike the arbor directly with a steel hammer when drifting it free from the spindle; use a soft-faced mallet or the machine drift slot with a brass drift to avoid shank damage.
