Value Collection SM0406450 Chucking Reamer 0.6450 in Hss

Product Description

The VALUE COLLECTION SM0406450 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6450-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill press or lathe chucks. With 6 right-hand flutes and a 2.25-inch flute length on a 9-inch overall length body, this reamer suits production and maintenance shops that require tight-tolerance hole finishing without regrinding carbide tooling.

This chucking reamer is intended for use in drill presses, lathes, and CNC machining centers where a floating or rigid chuck holds the straight shank. It is well suited to general metalworking, toolroom, and maintenance-repair-operations (MRO) environments. Typical applications include finish-reaming pin bores, bushing seats, and shaft holes in steel, cast iron, aluminum, and brass workpieces where the target diameter falls within the 0.5000- to 0.6999-inch range.

Key Features

• 0.6450-inch finished-hole diameter for precise, repeatable sizing
• High-speed steel (HSS) construction handles intermittent cuts and moderate heat without chipping
• 6 straight flutes with right-hand cutting direction provide smooth chip evacuation and a clean bore finish
• Bright uncoated finish simplifies resharpening on standard tool-and-cutter grinders
• Straight-cylindrical shank fits standard drill chucks, collet chucks, and floating reamer holders
• 9-inch overall length provides reach for deeper setups while keeping the tool rigid

Compatibility

Designed as a general-purpose chucking reamer for metalworking applications requiring a 0.6450-inch finished bore diameter; fits any machine tool equipped with a chuck or collet capable of holding a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by machinists and toolroom technicians. Before mounting, power down and lock out the machine spindle. Secure the straight shank fully in a drill chuck, collet, or floating holder with minimal runout to prevent bell-mouthing the bore. Always apply a cutting fluid appropriate for the workpiece material, and feed at a reduced rate compared to drilling to achieve the specified finish diameter.
