Value Collection SM2300112 Spiral Shell Reamer 1-3/16 in

Product Description

The VALUE COLLECTION SM2300112 is a spiral shell reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel, this reamer features a left-hand spiral flute with a right-hand cutting direction, a combination that helps control chip evacuation during through-hole reaming operations. It measures 1.1875 inches in diameter with an overall length of 2.75 inches and accepts a Number 6 arbor via a 5/8-inch center hole. This tool is suited for machinists, tool-and-die professionals, and maintenance technicians who need accurate bore sizing in production or repair environments.

Shell reamers are used where a separate arbor drive is required, typically in manual or machine-spindle reaming of pre-drilled bores that need tight dimensional tolerance. This model is appropriate for finishing holes in ferrous and non-ferrous metals in both job-shop and production-floor settings. The high-speed steel construction handles moderate cutting speeds and is compatible with standard cutting fluids used in machine shop operations.

Key Features

• 1.1875-inch reamer diameter for precise bore finishing
• High-speed steel construction for durability across metalworking applications
• Left-hand spiral flute geometry aids chip control during cutting
• Right-hand cutting direction for standard spindle rotation
• 5/8-inch center hole fits Number 6 arbor for secure drive engagement
• Compact 2.75-inch overall length suits close-quarters setups

Compatibility

Designed for use with Number 6 arbors featuring a 5/8-inch pilot. Suitable as an OEM-style shell reamer for manual and CNC machine spindle reaming operations requiring a 1-3/16-inch finished bore diameter.

Installation Notes

Shell reamers must be mounted on a correctly sized arbor before use — never attempt to chuck directly on the center hole. Always power down and lock out the machine spindle before mounting or removing the reamer. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. This tool should be installed and operated by qualified machinists or toolroom technicians following applicable shop safety procedures.
