Value Collection 331-2209 Shell Reamer Arbor Straight Shank

Product Description

The VALUE COLLECTION 331-2209 is a straight-shank shell reamer arbor designed to mount and drive shell reamers in metalworking and machining applications. The arbor features a 1-3/8 inch shank diameter and an overall length of 13 inches, providing the reach and rigidity needed for accurate reaming operations on the shop floor or in the field. It accommodates shell reamers ranging from 2-1/16 inches to 2-1/2 inches in diameter. This type of arbor is used by machinists and tool-and-die tradespeople who require a secure, concentric connection between the machine spindle and the shell reamer cutting head.

This shell reamer arbor is suited for use in manual and CNC machining environments where shell reamers must be driven with precision and minimal runout. It is appropriate for enlarging and finishing bored holes to close tolerances in ferrous and non-ferrous materials. The straight shank design allows mounting in standard drill press chucks, milling machine spindles, or lathe tailstocks. Typical applications include production shops, maintenance machining, and job-shop work where multiple reamer sizes share a common arbor platform.

Key Features

• Accepts shell reamers from 2-1/16 inches to 2-1/2 inches in diameter
• 1-3/8 inch straight shank diameter for standard spindle and chuck mounting
• 13 inch overall length provides reach for deeper bore applications
• Straight shank design simplifies installation in drill presses, mills, and lathes
• Single arbor supports a range of shell reamer sizes, reducing tooling changeover

Compatibility

Designed as an OEM-style replacement or direct-use arbor for shell reamers with a diameter range of 2-1/16 inches to 2-1/2 inches, mounted via a 1-3/8 inch straight shank in compatible machine spindles or chucks.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully powered down and at rest before mounting or removing the arbor. Verify that the chuck or collet is rated for the 1-3/8 inch shank diameter and that all locking hardware is properly secured before operating. Inspect the arbor and shell reamer seat for debris or damage before each use to maintain concentricity and prevent premature tool wear.
