Value Collection SM2300144 Spiral Shell Reamer 1-11/16 in

Product Description

The VALUE COLLECTION SM2300144 is a spiral shell reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel, this reamer features a spiral flute geometry with a left-hand spiral direction and right-hand cutting direction. It measures 1-11/16 inches (1.6875 inches) in diameter with an overall length of 3-1/2 inches. A 1-inch center hole accommodates an arbor-mounted setup, and the tool is compatible with a No. 8 arbor. Machinists and tool-and-die professionals use this reamer to bring bored or drilled holes to a precise final diameter with a clean surface finish.

This spiral shell reamer is suited for machine shop use in both production and maintenance environments. The shell-style body mounts to a separate arbor, which allows the cutting head to be replaced independently of the drive shank — a practical advantage in high-volume or precision-tolerance work. The right-hand cutting direction is compatible with standard spindle rotation on most lathes, milling machines, and drill presses. The left-hand spiral flute assists in directing chips away from the finished bore during the cut.

Key Features

• High-speed steel construction for durability in ferrous and non-ferrous materials
• Left-hand spiral flute geometry for controlled chip evacuation
• Right-hand cutting direction compatible with standard machine spindle rotation
• Shell-style body with 1-inch center hole mounts to a No. 8 arbor for flexible tooling setups
• 1-11/16 inch (1.6875 inch) diameter for precise hole finishing to final tolerance
• Compact 3-1/2 inch overall length suits standard machine tool setups

Compatibility

Designed for use with a No. 8 arbor and a 1-inch center hole mounting interface, consistent with standard shell reamer arbor systems used on lathes, mills, and drill presses.

Installation Notes

Shell reamers are installed by a machinist 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. Verify arbor size and center hole fit before applying cutting pressure. Use appropriate cutting fluid for the workpiece material to maintain tool life and surface finish quality.
