Value Collection SM0407840 Chucking Reamer 0.784 in Hss

Product Description

The VALUE COLLECTION SM0407840 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Machined from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores to a finished diameter of 0.7840 inches. The straight-cylindrical shank mounts directly in a drill chuck or collet holder on a drill press, lathe, or CNC machine. With an overall length of 9.5 inches and a 2.5-inch flute length, it provides adequate reach for standard through-holes and shallow blind holes in production and maintenance machining environments. Cutting direction is right hand.

This chucking reamer is suited for machine shop, toolroom, and maintenance applications where reamed-to-size holes are required. It is appropriate for use on mild steel, aluminum, brass, and similar machinable materials. The 0.7840-inch diameter falls within the 0.7000 to 0.9999 inch decimal inch reamer range, making it a practical choice for finishing drilled holes to close-tolerance dimensions in both production runs and one-off repair work.

Key Features

• 0.7840-inch finished reamed diameter for close-tolerance hole sizing
• High-speed steel (HSS) construction for durability across a range of machinable metals
• Straight flute design suits through-holes and materials that do not require spiral chip evacuation
• Bright, uncoated finish — no additional coating to affect dimensional tolerance
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction for standard machine spindle rotation

Compatibility

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

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Secure the shank firmly in a chuck or collet and verify runout before cutting. Power down the machine completely before changing or inspecting the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
