Value Collection 331-2116 Shell Reamer Arbor 5MT

Product Description

The VALUE COLLECTION 331-2116 is a No. 11 shell reamer arbor designed to mount and drive shell reamers in precision machining and metalworking applications. The arbor accepts shell reamers ranging from 3-1/16 inches to 3-1/2 inches in diameter and features a 5MT Morse taper shank for secure, concentric seating in compatible spindles and tailstocks. At 15 inches overall length and a maximum arbor diameter of 1-3/4 inches, this tool is built for heavy-duty reaming operations where accurate hole finishing is critical. Machinists and toolroom professionals select this arbor for its direct compatibility with standard shell reamer sizing conventions.

This arbor is suited for use in manual and CNC lathes, milling machines, and boring mills equipped with a No. 5 Morse taper spindle. It is appropriate for production and toolroom environments where shell reamers must be driven repeatedly with consistent alignment. Typical applications include finishing bored holes to precise diameters in ferrous and non-ferrous workpieces. The No. 11 arbor number corresponds to a standardized sizing system, making selection straightforward when paired with matching shell reamers.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before mounting or removing the arbor. Ensure the Morse taper surfaces on both the arbor and the spindle socket are clean and free of nicks or burrs before seating. Use a proper drift and mallet to remove the arbor; never pry against the reamer or arbor body.
