Value Collection SM0406430 Chucking Reamer 0.6430 in Hss

Product Description

The VALUE COLLECTION SM0406430 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6430-inch diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate hole sizing in ferrous and non-ferrous materials on manual or CNC lathes, drill presses, and milling machines. The straight-cylindrical shank seats securely in a drill chuck or collet, and the right-hand cutting direction suits standard spindle rotation. At 9 inches overall length with a 2.25-inch flute length, this reamer handles typical through-hole and shallow blind-hole applications in production and job-shop environments. Licensed machinists and toolroom professionals are the primary users.

This chucking reamer is suited for metalworking operations requiring tight hole-tolerance finishing in the 0.5000- to 0.6999-inch diameter range. Typical applications include sizing bearing bores, bushing fits, and pin locations in steel, cast iron, aluminum, and brass workpieces. It is used in job shops, maintenance and repair operations, and light manufacturing where a precise, smooth bore finish is required. The 6-flute configuration improves surface finish and distributes cutting load evenly compared to fewer-flute designs.

Key Features

• 0.6430-inch reamer diameter for precise hole finishing to close tolerances
• High-speed steel (HSS) construction provides toughness and wear resistance across common workpiece materials
• 6 straight flutes deliver improved surface finish and balanced cutting forces
• Right-hand cutting direction compatible with standard spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collets without an adapter
• Bright, uncoated finish suitable for general-purpose reaming with cutting fluid

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and milling machines equipped with a drill chuck or collet capable of holding a straight-cylindrical shank in the 0.5000- to 0.6999-inch diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom technicians. Secure the straight shank firmly in a drill chuck or collet before operation and verify runout is within acceptable limits to avoid bell-mouthing the bore. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Feed rate and spindle speed should follow standard reaming practice for the material being cut — typically lower RPM and higher feed than drilling.
