Value Collection 331-2208 Shell Reamer Arbor No. 8

Product Description

The VALUE COLLECTION 331-2208 is a No. 8 shell reamer arbor designed to mount and drive shell reamers in precision boring and reaming operations. It features a 1-1/8 inch cylindrical (straight) shank that fits standard machine tool spindles and tool holders. The arbor accepts shell reamers ranging from 1-11/16 inches to 2 inches in diameter and has a maximum arbor diameter of 1-1/8 inches. Overall length is 12 inches. Machinists and tool-and-die professionals use this arbor when finishing bored holes to tight tolerances in production or job-shop environments.

This shell reamer arbor is suited for use on manual lathes, milling machines, and boring mills where shell reamers must be driven with a secure, concentric connection. The straight shank allows direct chucking or collet mounting without additional adapters in most setups. It is a general-purpose arbor appropriate for both production runs and maintenance machining where hole finishing in the 1-11/16 inch to 2 inch range is required.

Installation Notes

Installation is performed by qualified machinists. Ensure the machine spindle and tool holder are fully powered down and locked out before mounting or removing the arbor. The straight shank should be clean and free of burrs before seating in the chuck or collet. Verify runout with a dial indicator after mounting to confirm concentricity before beginning the reaming operation.
