Value Collection SM2300304 Spiral Shell Reamer 3-1/16 in

Product Description

The VALUE COLLECTION SM2300304 is a spiral shell reamer designed for precision hole finishing in metalworking and machining applications. Built from high-speed steel, this reamer delivers consistent, accurate results when enlarging or finishing pre-bored holes to a final diameter of 3.0625 inches. The spiral flute geometry with a left-hand spiral and right-hand cutting direction helps control chip evacuation and reduces chatter during the cut. With an overall length of 4.5 inches and a 1.75-inch center hole, it is sized for use with an arbor number 11 drive setup. Machinists and tool room professionals working on large-bore finishing operations are the primary users of this tool.

This shell reamer is suited for production and job-shop environments where large-diameter hole finishing is required. The arbor-mounted design makes it appropriate for use on drill presses, manual mills, and boring mills. It handles ferrous and non-ferrous materials typical in industrial machining, and the high-speed steel construction holds up under moderate cutting speeds without coolant in many applications. It is a single-piece unit packaged individually and ordered in single-unit quantities.

Key Features

• 3.0625-inch reamer diameter for large-bore hole finishing
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Left-hand spiral flute promotes controlled chip flow during right-hand cutting
• 1.75-inch center hole sized for arbor number 11 compatibility
• 4.5-inch overall length suits standard arbor-mount setups on drill presses and mills

Compatibility

Designed for use with arbor number 11 drive arbors. Intended for arbor-mounted reaming operations on drill presses, manual milling machines, and boring mills where a 3.0625-inch finished bore diameter is required.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with arbor-mounted cutting tools. Secure the arbor to the spindle and verify runout before cutting to avoid oversizing the bore. Power down the machine and lock out the spindle before mounting or removing the reamer. Follow applicable shop safety standards and the machine manufacturer guidelines for speed and feed selection with large-diameter shell reamers.
