Value Collection 246519 Machine Expansion Reamer 19/32 in

Product Description

The VALUE COLLECTION 246519 is a machine expansion reamer with a straight shank, designed for precision hole finishing in metalworking and machining applications. Built with a carbide-tipped cutting edge, it delivers consistent sizing performance across ferrous and non-ferrous materials. The 19/32-inch nominal diameter (0.5938 decimal inches) features a diameter tolerance of +0.0003 to -0.0000 inches and a guaranteed minimum expansion of 0.0100 inches, giving machinists controlled adjustment capability. With 6 straight flutes and an overall length of 8 inches, this reamer is suited for use in machine tool setups where repeatable bore accuracy is required. It is installed and operated by machinists and tool-and-die professionals.

This machine expansion reamer is intended for use in drill press, lathe, or milling machine setups where final bore sizing and surface finish are critical. The expansion feature allows the operator to fine-tune the cutting diameter within the specified range, reducing the need for multiple fixed-size reamers. The 1-1/8-inch flute length is appropriate for shallow to moderate depth holes. Right-hand cutting direction is standard for conventional machine tool spindle rotation. This tool is a fit for production shops, maintenance facilities, and job shops working with close-tolerance bore requirements.

Key Features

• Carbide-tipped cutting edges for extended tool life on hard and abrasive materials
• Adjustable expansion with a guaranteed minimum of 0.0100 inches for fine diameter tuning
• Diameter tolerance of +0.0003 to -0.0000 inches for close-tolerance bore finishing
• 6 straight flutes providing smooth, consistent chip evacuation
• Straight shank for direct chuck or collet mounting in standard machine spindles
• Right-hand cutting direction compatible with standard machine tool rotation
• Coated finish for improved wear resistance and reduced friction

Compatibility

Designed as an OEM-style machine expansion reamer for use in drill press, lathe, or milling machine setups requiring a straight-shank tool with a 19/32-inch nominal bore diameter.

Installation Notes

This reamer is installed and operated by qualified machinists. Secure the straight shank in a suitable chuck or collet and verify runout before use to maintain bore accuracy. Always power down and lock out the machine spindle before adjusting the expansion setting. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality.
