Value Collection SM2300320 Spiral Shell Reamer 3-5/16 in

Product Description

The VALUE COLLECTION SM2300320 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 geometry paired with a right-hand cutting direction, a combination that helps pull chips away from the workpiece and reduce chatter during the cut. The reamer measures 3-5/16 inches in diameter with an overall length of 4-1/2 inches, and accepts a No. 11 arbor through a 1-3/4 inch center hole. Machinists and tool-and-die professionals use this tool to bring bored or drilled holes to final dimensional tolerance.

This shell reamer is suited for production and maintenance machining environments where large-diameter holes require precise finishing. The arbor-mount design allows the reamer head to be swapped independently of the arbor, reducing tooling cost in high-cycle operations. It is appropriate for use on ferrous and non-ferrous metals in both manual and CNC machining setups where a No. 11 arbor is available.

Key Features

• High-speed steel construction for durability across a range of workpiece materials
• Left-hand spiral flute promotes chip evacuation and reduces chatter
• Right-hand cutting direction for standard machine spindle rotation
• Shell-style arbor mount accepts No. 11 arbor with 1-3/4 inch center hole
• 3-5/16 inch reamer diameter suitable for large-bore finishing work

Compatibility

Designed for use with No. 11 arbors in shell reamer configurations. Confirm arbor taper and drive lug dimensions match your toolholder before installation.

Installation Notes

Shell reamers are installed by a machinist or toolroom technician onto a compatible arbor before mounting in the machine spindle. Ensure the machine is fully de-energized and the spindle is locked before mounting or removing the reamer head. Use the correct arbor taper and confirm drive lugs are properly seated to prevent slippage during the cut. Follow your facility safety procedures and applicable OSHA machining standards when operating rotating cutting tools.
