Value Collection SM2300344 Spiral Shell Reamer 3-11/16 in

Product Description

The VALUE COLLECTION SM2300344 is a spiral shell reamer designed for precision hole finishing in metalworking and machining applications. Built from high-speed steel (HSS), it delivers consistent cutting performance and durability under demanding shop conditions. The reamer measures 3-11/16 inches in diameter with an overall length of 5 inches. It features a left-hand spiral flute geometry combined with a right-hand cutting direction, a configuration that reduces chatter and helps pull chips away from the cutting edge during operation. A 2-inch center hole accommodates standard arbor mounting, and the tool is rated for arbor number 12 compatibility.

This shell reamer is suited for production and maintenance machining environments where bore sizing and finishing are required. It is typically used on drill presses, milling machines, and lathes to bring a pre-drilled or bored hole to a precise final diameter. The arbor-mounted design makes it appropriate for shops handling medium-to-large diameter hole finishing in ferrous and non-ferrous materials. Machinists and toolroom technicians are the primary users of this style of reamer.

Key Features

• 3-11/16 inch reamer diameter for large-bore finishing operations
• High-speed steel construction for wear resistance and extended tool life
• Left-hand spiral flutes promote chip evacuation and reduce chatter
• Right-hand cutting direction for standard machine spindle rotation
• 2-inch center hole fits arbor number 12 for secure, repeatable mounting
• 5-inch overall length provides reach appropriate for typical shell reamer setups

Compatibility

Compatible with arbor number 12 mounting systems. Designed as an OEM-style shell reamer for use on standard drill press, milling machine, or lathe setups requiring a 3-11/16 inch finished bore diameter.

Installation Notes

Shell reamers must be mounted securely on the correct arbor before use. Always bring the workpiece bore to within the recommended stock allowance before reaming to avoid tool damage. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter before engaging the cut. Use appropriate cutting fluid for the material being reamed to extend tool life and achieve the desired surface finish.
