Value Collection SM0407850 Chucking Reamer 0.785 in Hss

Product Description

The VALUE COLLECTION SM0407850 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing on through-holes and blind holes where tight tolerances are required. The reamer measures 0.7850 inches in diameter with an overall length of 9.5 inches and a flute length of 2.5 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. Right-hand cutting direction suits conventional machine spindle rotation. Machinists and toolroom technicians are the primary installers and users of this tool.

This chucking reamer is suited for use in manual mills, drill presses, lathes, and CNC machining centers where a reamed finish bore is required. It is appropriate for both job shop and production environments handling steel, aluminum, brass, and similar machinable materials. The 0.7850-inch diameter falls within the 0.7000 to 0.9999 inch decimal range, making it a common selection for medium-bore finishing work. It ships individually and is sold in single-unit quantity.

Key Features

• High-speed steel (HSS) construction provides wear resistance across a broad range of machinable metals
• Straight flute geometry suits through-hole and short blind-hole reaming
• Bright, uncoated finish maintains dimensional accuracy and allows easy wear inspection
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for use with conventional machine spindle rotation

Compatibility

Designed as a standard decimal-inch chucking reamer for use in drill presses, milling machines, lathes, and CNC machining centers equipped with a drill chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists in accordance with standard shop practices. Always power down and lock out the machine spindle before changing tooling. Secure the straight-cylindrical shank fully within the chuck or collet to the recommended engagement depth before operating. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
