Value Collection SM2300108 Spiral Shell Reamer 1-1/8 in

Product Description

The VALUE COLLECTION SM2300108 is a spiral shell reamer designed for precision hole finishing in metalworking and machining applications. Built from high-speed steel, this reamer delivers consistent sizing and smooth surface finishes in drilled holes. It measures 1.125 inches in diameter with an overall length of 2.75 inches. The spiral flute geometry with left-hand spiral and right-hand cutting direction reduces chatter and improves chip evacuation during the reaming pass. A 5/8-inch center hole accepts a No. 6 arbor for secure machine mounting. Machinists and toolroom professionals use this tool when bore tolerances require finishing beyond what a standard drill provides.

This reamer is suited for light to medium stock removal in ferrous and non-ferrous metals. The right-hand cutting action is compatible with standard spindle rotation on most manual and CNC machine tools, including drill presses, lathes, and knee mills. The arbor-mount design makes it easy to swap between machines when production setups require consistent hole sizing across multiple workpieces.

Key Features

• 1.125-inch reamer diameter for accurate hole finishing to size
• High-speed steel construction for durability across a range of ferrous and non-ferrous materials
• Left-hand spiral flutes promote chip pulling and reduce chatter
• Right-hand cutting direction compatible with standard machine spindle rotation
• 5/8-inch center hole fits No. 6 arbor for positive, concentric mounting
• Compact 2.75-inch overall length suits close-clearance and short-reach setups

Compatibility

Designed for use with No. 6 arbors featuring a 5/8-inch center hole. Suitable for standard drill presses, lathes, and milling machines equipped with compatible arbor tooling.

Installation Notes

Install this reamer into a No. 6 arbor and verify runout before engaging the workpiece, as excessive runout will cause bell-mouthing and oversize holes. Always ream at reduced spindle speeds compared to drilling, and apply appropriate cutting fluid for the material being machined. Secure the workpiece firmly before operation to prevent movement during the reaming pass. Allow the reamer to come to a full stop before reversing or removing it from the hole.
