Harvey Tool RSB0465-C3 Chucking Reamer Size 56 Solid Carbide

Product Description

The HARVEY TOOL RSB0465-C3 is a miniature solid carbide chucking reamer designed to finish-ream precision holes to tight tolerances in small-diameter applications. Built to a wire gauge size 56 (0.0465 inch decimal diameter), this reamer holds a tolerance of +0.0002 to 0.0000 inches, making it well-suited for work that demands consistent, repeatable hole sizing. The 4-flute, straight-flute geometry cuts in a right-hand direction and is ground from solid carbide for rigidity and wear resistance. An AlTiN coating adds heat resistance for improved tool life in harder materials. At 2 inches overall length with a 5/16-inch flute length and a 1/8-inch straight-cylindrical shank, this tool fits standard precision chucks and collet systems.

This miniature reamer is used in close-tolerance holemaking across precision machining, instrument manufacturing, watchmaking, medical device fabrication, and electronics assembly. Its compact geometry makes it appropriate wherever small-bore accuracy is required and conventional tooling is too large. The straight-cylindrical shank seats cleanly in 1/8-inch collet chucks or drill chucks on CNC machining centers, manual mills, and benchtop drilling equipment. It is intended for installation by machinists and toolroom personnel working to blueprint or specification tolerances.

Key Features

• Wire gauge size 56 diameter: 0.0465 inch decimal equivalent
• Solid carbide construction for rigidity and dimensional stability in small-bore applications
• AlTiN coating for elevated heat resistance and extended tool life
• 4-flute straight geometry with right-hand cutting direction
• Tight reaming tolerance: +0.0002 to 0.0000 inches
• 1/8-inch straight-cylindrical shank compatible with standard precision collet systems

Compatibility

Designed as an OEM-style precision cutting tool for use in standard 1/8-inch collet chucks and drill chucks on CNC machining centers, manual knee mills, and benchtop drilling equipment where miniature-diameter reaming is required.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the tool from the collet or chuck. Verify collet bore size matches the 1/8-inch shank diameter before clamping. Do not exceed the recommended feed and speed parameters for the workpiece material, as solid carbide miniature tools are brittle and susceptible to breakage under side load or excessive feed pressure.
