Value Collection SM2300352 Spiral Shell Reamer 3-13/16 in

Product Description

The VALUE COLLECTION SM2300352 is a spiral shell reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel, this reamer measures 3-13/16 inches in diameter with a 5-inch overall length. It features a left-hand spiral flute geometry paired with a right-hand cutting direction, a combination that reduces chatter and produces a clean, accurate bore finish. A 2-inch center hole accommodates arbor mounting, and the tool is rated for No. 12 arbor compatibility. Machinists and tool-room technicians rely on shell reamers like this for finishing bores to tight tolerances in production or maintenance environments.

This shell reamer is suited for machine shop, toolroom, and industrial maintenance applications where large-diameter bore finishing is required. The arbor-mounted design makes it appropriate for use on lathes, milling machines, and boring mills. At 3-13/16 inches diameter, it targets large-bore finishing tasks common in heavy equipment, pump housings, and industrial component manufacture. Installation requires a compatible No. 12 arbor, which is sourced separately. Right-hand cutting direction supports conventional feed on standard spindle setups.

Key Features

• 3-13/16 inch reamer diameter for large-bore finishing applications
• High-speed steel construction provides durability and heat resistance during cutting
• Left-hand spiral flutes reduce chatter and improve surface finish quality
• Right-hand cutting direction compatible with standard spindle rotation
• 2-inch center hole for secure arbor mounting
• No. 12 arbor compatibility for use with standard shell reamer arbors

Compatibility

Designed for use with No. 12 shell reamer arbors. Arbor is not included and must be sourced separately.

Installation Notes

Shell reamers are installed by qualified machinists or toolroom technicians. Before mounting, ensure the machine spindle is fully powered down and locked out per OSHA lockout/tagout procedures. Verify arbor size matches the 2-inch center hole before seating the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
