Value Collection SM0407900 Chucking Reamer Hss 0.79in

Product Description

The VALUE COLLECTION SM0407900 is a straight-flute chucking reamer machined from high-speed steel (HSS) and designed to finish-ream holes to a precise 0.7900-inch diameter. It runs right-hand cutting and is intended for use in drill presses, lathes, and CNC machining centers where hole tolerance and surface finish matter. The bright, uncoated finish keeps friction low during light to moderate reaming passes. At 9.5 inches overall length with a 2.5-inch flute length, it reaches into deeper bores without sacrificing rigidity. Machinists and tool-and-die professionals use this style of reamer to bring pre-drilled or bored holes up to final dimension with tight concentricity.

This chucking reamer fits standard machine-tool chucks and collet systems that accept a straight-cylindrical shank. It is suited for general metalworking applications in job shops, maintenance facilities, and production environments. Typical materials include mild steel, aluminum, brass, and similar machinable alloys. The straight-cylindrical shank allows easy setup in any chuck with adequate bore diameter to grip a shank in the 0.79-inch class. The reamer is sold individually and is appropriate for both low-volume repair work and repetitive production reaming at moderate feeds and speeds.

Key Features

• 0.7900-inch finished hole diameter for precise tolerance control
• High-speed steel (HSS) construction handles a wide range of machinable metals
• Straight flute geometry delivers smooth cutting action and easy chip clearance
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright, uncoated finish reduces built-up edge on non-ferrous and mild steel cuts
• Straight-cylindrical shank fits drill chucks and collet holders without adapters

Compatibility

Designed as a general-purpose chucking reamer for use in any machine tool equipped with a chuck or collet system capable of gripping a straight-cylindrical shank in the 0.79-inch diameter range, including drill presses, engine lathes, and machining centers.

Installation Notes

A licensed machinist or experienced tool operator should set up and run this reamer. Power down and de-energize the machine spindle completely before loading or removing the tool from the chuck. Always apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Do not use this reamer to remove excessive stock — pre-drill or bore the hole to near-final size before reaming to final dimension.
