Value Collection SM2200360 Straight Shell Reamer 3-15/16 in

Product Description

The VALUE COLLECTION SM2200360 is a straight-flute shell reamer designed for precision bore finishing in metalworking applications. Built from high-speed steel, it delivers consistent cutting performance on ferrous and non-ferrous materials. The reamer measures 3-15/16 inches in diameter with a 5-inch overall length, and it accepts a No. 12 arbor through a 2-inch center hole. Right-hand cutting direction makes it compatible with standard drill press and milling machine spindle rotation. Machinists and tool-and-die professionals use shell reamers of this size to hold tight tolerances on large-diameter bores during production or repair work.

This shell reamer is suited for heavy-duty bore sizing and finishing operations in job shops, maintenance facilities, and production machining environments. It is typically used on drill presses, milling machines, or horizontal boring equipment where a No. 12 arbor is already in service. At 3-15/16 inches in diameter, this tool handles large-bore finishing tasks that exceed the capacity of most solid or expansion reamers, making it a practical choice for industrial and toolroom applications requiring accurate final-pass sizing.

Key Features

• High-speed steel construction provides wear resistance and heat tolerance during extended cutting operations
• Straight flute geometry produces consistent surface finish and is well-suited for through-bore applications
• 3-15/16 inch (3.9375 inch) diameter for large-bore finish reaming
• 5-inch overall length balances reach with rigidity in typical machine setups
• 2-inch center hole sized for No. 12 arbor compatibility
• Right-hand cutting direction matches standard machine spindle rotation

Compatibility

Designed for use with a No. 12 arbor. Shell reamers of this type mount to a matching arbor and are a standard OEM-style replacement or upgrade for large-bore finishing setups on drill presses and milling machines that accept No. 12 arbor tooling.

Installation Notes

Installation is performed by a qualified machinist. Mount the shell reamer securely onto a No. 12 arbor before installing the assembly into the machine spindle. Ensure the machine is fully powered down and the spindle is locked before mounting or removing tooling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
