Value Collection 331-2010 Shell Reamer Arbor No. 8

Product Description

The VALUE COLLECTION 331-2010 is a No. 8 shell reamer arbor designed to mount and drive shell reamers in precision machining and metalworking operations. It features a straight shank measuring 1-1/8 inches in diameter and an overall length of 12 inches, providing rigid support for shell reamers ranging from 1-11/16 to 2 inches in diameter. This arbor serves as the interface between the machine spindle and the shell reamer body, transmitting rotational force accurately during reaming operations. It is used by machinists and toolroom professionals in lathes, milling machines, and boring applications where close-tolerance hole finishing is required.

This arbor is suited for production and toolroom environments where shell reamers in the 1-11/16 to 2 inch range are in regular use. The 12-inch overall length accommodates setups requiring additional reach, and the 1-1/8-inch straight shank allows mounting in standard collet chucks or tool holders sized for that bore. It is packaged individually and sold as a single unit.

Key Features

• No. 8 arbor designation for shell reamers from 1-11/16 to 2 inches in diameter
• 1-1/8 inch straight shank for standard chuck or collet holder mounting
• 12 inch overall length for extended reach setups
• Rigid arbor body supports accurate, chatter-reduced reaming cuts
• Single-piece construction for consistent concentricity between shank and reamer seat

Compatibility

Designed for use with No. 8 shell reamers having a reamer diameter between 1-11/16 and 2 inches. Confirm arbor number and pilot diameter against the shell reamer manufacturer's specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist familiar with arbor and reamer assembly procedures. Ensure the machine spindle is fully powered down and locked out before mounting or removing the arbor. Verify that the shank fits the tool holder bore without excessive clearance, and that the shell reamer is properly seated and secured on the arbor before beginning a cut. Follow applicable shop safety standards and machine manufacturer guidelines for tooling installation.
