Harvey Tool RSB0810-C3 Chucking Reamer Size 46 Carbide

Product Description

The HARVEY TOOL RSB0810-C3 is a solid carbide chucking reamer designed for precision holemaking in tight-tolerance applications. Built to a wire gauge size 46 (0.0810 inches diameter), this 4-flute, right-hand cutting reamer features a straight flute geometry and an AlTiN coating for improved wear resistance and tool life. The overall length is 2 inches with a 9/16-inch flute length, making it well-suited for miniature reaming operations. Diameter tolerance is held to +0.0002 to 0.0000 inches, which is critical when fitting dowel pins or producing close-tolerance bores. Machinists and toolroom technicians install this reamer in CNC machining centers, drill presses, or manual mills.

This reamer is part of the Harvey Tool Miniature Reamers series, intended for small-diameter precision work in industries where tight bore tolerances are non-negotiable. Typical applications include aerospace components, medical device machining, mold and die work, and any operation requiring accurate sub-0.1-inch diameter holes. The straight-cylindrical shank mounts directly into standard collets or drill chucks. It is used in both prototype and production environments where bore finish and dimensional accuracy are the primary concerns.

Key Features

• Wire gauge size 46 reamer diameter of 0.0810 inches for miniature precision holemaking
• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• AlTiN coating extends tool life and supports dry or semi-dry cutting conditions
• 4-flute straight geometry produces consistent bore finish and chip clearance
• Diameter tolerance of +0.0002 to 0.0000 inches ensures close-tolerance bore fitment
• Right-hand cutting with straight-cylindrical shank for direct collet or chuck mounting

Compatibility

Designed as an OEM-style miniature chucking reamer compatible with standard straight-bore collets and drill chucks sized for small-shank tooling. No specific machine model compatibility was provided by the manufacturer for this SKU.

Installation Notes

This reamer is installed by machinists and toolroom technicians in CNC or manual machine spindles using a collet or drill chuck matched to the shank diameter. Ensure the workpiece and machine spindle are secured before engaging the reamer. Pre-drill or bore the hole to the recommended pilot diameter prior to reaming to avoid tool deflection or overloading the flutes. Do not reverse spindle direction during tool engagement, as this reamer is designed for right-hand cutting only.
