Value Collection SM2300216 Spiral Shell Reamer 2.25 in

Product Description

The VALUE COLLECTION SM2300216 is a spiral shell reamer designed for precision hole finishing and sizing in metalworking applications. With a 2.25-inch diameter and a 3.75-inch overall length, this reamer removes minimal material to bring bored or drilled holes to accurate final dimensions. Constructed from high-speed steel, it offers the hardness and wear resistance needed for sustained performance in production and maintenance shop environments. The left-hand spiral flute geometry combined with right-hand cutting action helps pull chips away from the cutting zone, reducing chatter and improving surface finish. A 1.25-inch center hole accepts an arbor for secure, concentric mounting during use.

This shell reamer is suited for machine shop, maintenance, and tool room work where close-tolerance hole finishing is required. It is used in drill press, lathe, or milling machine setups where an arbor is used to drive the tool. Arbor Number 9 compatibility determines the correct driving arbor for this reamer. Typical applications include finishing holes in steel, cast iron, and similar ferrous materials where dimensional accuracy and surface quality are critical.

Key Features

• 2.25-inch reamer diameter for precision hole sizing
• High-speed steel construction for hardness and wear resistance
• Spiral flute design reduces chatter and improves chip evacuation
• Right-hand cutting direction for standard machine rotation
• Left-hand spiral direction aids chip clearing during cutting
• 1.25-inch center hole sized for Arbor Number 9 compatibility

Compatibility

Designed for use with Arbor Number 9 driving arbors. Shell reamer style requires a separate arbor for mounting and operation.

Installation Notes

This reamer is installed by a machinist or tool room technician onto a compatible Arbor Number 9 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 improve finish quality. Verify arbor fit and reamer seating before beginning any cutting operation.
