Value Collection SM2300212 Spiral Shell Reamer 2-3/16 in

Product Description

The VALUE COLLECTION SM2300212 is a spiral shell reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel, this reamer measures 2.1875 inches (2-3/16 inches) in diameter with an overall length of 3-3/4 inches. It features a left-hand spiral flute geometry paired with a right-hand cutting direction, a combination that reduces chatter and helps pull chips away from the cutting edge during operation. The center hole measures 1-1/4 inches and accepts a No. 9 arbor. This tool is suited for machinists and toolroom technicians working on bore finishing and sizing operations where dimensional accuracy is the priority.

Shell reamers of this diameter range are commonly used in production and job-shop machining environments for finishing pre-bored or pre-drilled holes to tight tolerances. The arbor-mounted design allows the reamer to be driven by a standard machine spindle or reamer driver. Typical applications include finishing holes in ferrous and non-ferrous metals on lathes, drill presses, and milling machines. This size is well suited to medium and large-bore finishing work where a solid-shank reamer would be impractical.

Key Features

• 2.1875 inches (2-3/16 inches) reamer diameter for medium-to-large bore finishing
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Left-hand spiral flutes promote chip evacuation and reduce chatter
• Right-hand cutting direction for standard machine spindle compatibility
• No. 9 arbor compatibility with 1-1/4 inches center hole
• 3-3/4 inches overall length suits typical machine setups

Compatibility

Designed for use with No. 9 shell reamer arbors. Confirm arbor taper and drive compatibility with your machine spindle before installation.

Installation Notes

Shell reamers are installed by a machinist onto a matching arbor before mounting in the machine spindle. Ensure the machine is fully powered down and the spindle is locked before mounting or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not exceed the recommended feed and speed parameters for high-speed steel tooling in the material being machined.
