Value Collection SM2300356 Spiral Shell Reamer 3-7/8 in

Product Description

The VALUE COLLECTION SM2300356 is a spiral shell reamer designed for precision hole finishing in metalworking and machining applications. Built from high-speed steel, this reamer delivers consistent cutting performance and wear resistance across a range of materials. It measures 3-7/8 inches in diameter with a 5-inch overall length, and features a 2-inch center hole for arbor mounting. The spiral flute geometry, combined with a right-hand cutting direction and left-hand spiral, reduces chatter and produces a smooth bore finish. Machinists and toolroom technicians use this style of reamer to bring drilled or bored holes to precise final dimensions.

This shell reamer is suited for production machining, toolroom work, and maintenance operations where accurate hole sizing is required. Its arbor-mounted design is compatible with No. 12 arbors, making it practical for use on milling machines, lathes, drill presses, and boring mills. The large diameter makes it appropriate for finishing holes in heavier workpieces such as housings, fixtures, and structural components. It is used in both job shop and production floor environments.

Key Features

• 3-7/8 inch reamer diameter for large-bore hole finishing
• High-speed steel construction for durability and heat resistance
• Spiral flute design reduces chatter and improves surface finish
• Right-hand cutting direction with left-hand spiral for smooth stock removal
• 2-inch center hole fits No. 12 arbor for secure machine mounting
• 5-inch overall length suited for standard depth applications

Compatibility

Designed for use with No. 12 arbors. Fits standard arbor-mount tool holders compatible with that arbor designation on milling machines, lathes, and drill presses.

Installation Notes

Shell reamers are installed and removed by a machinist or toolroom technician. Power down the machine and secure the spindle before mounting or removing the reamer from its arbor. Ensure the arbor is clean and properly seated before tightening. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the desired surface finish.
