Value Collection 331-2310 Shell Reamer Arbor 5MT 14in

Product Description

The VALUE COLLECTION 331-2310 is a No. 10 shell reamer arbor designed to mount and drive shell reamers in machine tool applications. It features a 5MT (No. 5 Morse Taper) shank for direct mounting in compatible spindles and has an overall length of 14 inches. The arbor accepts shell reamers ranging from 2-9/16 inches to 3 inches in diameter, covering a practical range of large-bore finishing work. This arbor is the interface between the machine spindle and the shell reamer cutting head, transferring torque and maintaining concentricity during reaming operations. It is typically installed by machinists and toolroom technicians in production and job-shop environments.

This arbor is suited for use in drill presses, milling machines, and lathes equipped with a No. 5 Morse Taper spindle. It supports shell reamer operations on large-diameter bores requiring precise finishing passes. Typical applications include bearing bore finishing, bushing fits, and close-tolerance hole sizing in metal fabrication and machining operations where shell reamers in the 2-9/16 inch to 3 inch range are specified.

Compatibility

Designed to accept No. 10 shell reamers with cutting diameter range of 2-9/16 inches to 3 inches, mounted in machine spindles with a No. 5 Morse Taper socket.

Installation Notes

Installation is performed by machinists or toolroom personnel. Before mounting or removing the arbor, ensure the machine spindle is fully stopped and power is locked out per shop lockout/tagout procedures. Clean both the arbor taper and the spindle socket thoroughly before seating to ensure full taper contact and prevent runout. Use a proper drift and mallet to remove the arbor from the spindle — never apply side load to the shank.
