Value Collection 331-2004 Shell Reamer Arbor Straight Shank

Product Description

The VALUE COLLECTION 331-2004 is a shell reamer arbor designed to mount shell reamers for precision hole finishing in metalworking and machining applications. The arbor features a 0.625 inch straight shank for secure chuck or collet holding, with an overall length of 9.5 inches to provide the reach and rigidity needed during reaming operations. It accepts shell reamers ranging from 0.8125 inches to 1.03125 inches in diameter, making it appropriate for a focused range of medium-bore finishing work. Machinists and tool and die professionals typically install and use this arbor in manual or CNC mill setups.

This shell reamer arbor is suited for machine shop environments where reaming operations require a removable, mountable shell reamer rather than a solid reamer. Typical applications include finish-reaming bored holes to tight tolerances in steel, cast iron, aluminum, and similar materials. The arbor allows the shell reamer to be replaced independently, reducing tooling cost over time. It is commonly used in production and job-shop environments on vertical mills, drill presses, and horizontal machining centers.

Key Features

• Accepts shell reamers from 0.8125 inches to 1.03125 inches in diameter
• 0.625 inch straight shank for standard chuck or collet mounting
• 9.5 inch overall length provides reach for deeper bore applications
• Separable arbor design allows shell reamer replacement without discarding the arbor
• Sold individually, quantity of one per package

Compatibility

Designed for use with shell reamers having a compatible mounting bore, accommodating shell reamer diameters from 0.8125 inches to 1.03125 inches. Verify arbor and reamer mounting dimensions before installation.

Installation Notes

Installation is typically performed by machinists in a machine shop environment. Ensure the machine spindle is powered down and fully stopped before mounting or removing the arbor. Verify that shank diameter matches the chuck or collet size before clamping. Secure the shell reamer to the arbor according to the reamer and arbor manufacturer mounting requirements before beginning any reaming operation.
