Value Collection SM2300104 Spiral Shell Reamer 1-1/16 in

Product Description

The VALUE COLLECTION SM2300104 is a spiral shell reamer designed for precision hole finishing and sizing in metalworking applications. Built from high-speed steel, this reamer measures 1-1/16 inches (1.0625 inches decimal) in diameter with an overall length of 2-3/4 inches. It features a spiral flute geometry with a left-hand spiral direction and right-hand cutting direction, a combination commonly used to reduce chatter and produce clean, accurate bores. A 5/8-inch center hole accommodates Number 6 arbor compatibility for secure mounting on a driven spindle. Installation and operation are typically performed by machinists or tool and die professionals in shop environments.

This shell reamer is suited for finish-reaming pre-bored or drilled holes to precise tolerances in ferrous and non-ferrous metals. The arbor-mounted design makes it appropriate for use on drill presses, lathes, and milling machines where controlled feed rates and rigid setups are maintained. Its high-speed steel construction handles moderate cutting speeds and is well-suited for general-purpose production and maintenance machining work.

Key Features

• 1-1/16 inch (1.0625 inch) reamer diameter for precise hole finishing
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Spiral flute geometry with left-hand spiral reduces chatter during cutting
• Right-hand cutting direction for standard spindle rotation
• 5/8-inch center hole fits Number 6 arbor for secure driven mounting
• Compact 2-3/4 inch overall length suits close-tolerance and confined-space applications

Compatibility

Designed for use with Number 6 arbors featuring a 5/8-inch pilot. Suitable as an OEM-style replacement or direct application shell reamer for drill presses, lathes, and milling machine setups requiring a 1-1/16 inch finish bore.

Installation Notes

Shell reamers are installed and operated by machinists using an appropriate arbor mounted in a rigid machine spindle. Power down and de-energize the machine before mounting or removing the reamer from the arbor. Use proper cutting fluid for the workpiece material to extend tool life and achieve surface finish targets. Avoid hand-feeding at excessive rates, as overfeeding can damage the cutting edges and produce out-of-tolerance bores.
