Harvey Tool RSB0635-C3 Chucking Reamer Size 52 Solid Carbide

Product Description

The HARVEY TOOL RSB0635-C3 is a solid carbide chucking reamer in the Miniature Reamers series, designed for precision hole finishing in small-diameter applications. It produces a 0.0635 inch diameter bore with a tight tolerance of +0.0002 to -0.0000 inches, making it suitable for close-tolerance work where dimensional accuracy is critical. The 4-flute, straight-flute geometry paired with an AlTiN coating supports cutting in hardened steels, stainless alloys, and other abrasive materials. With a 2 inch overall length and a 7/16 inch flute length, this tool is sized for use in CNC machining centers, drill presses, and manual machine tools where a straight-cylindrical shank is required. Machinists, toolroom technicians, and precision manufacturing shops are the primary users.

This reamer is used in holemaking and threading operations requiring sub-0.1 inch bore diameters, classified under wire gauge size 52. It fits residential and commercial machining environments wherever miniature precision bores are required, including aerospace component work, medical device manufacturing, mold and die work, and general precision machining. The straight-cylindrical shank allows direct mounting in standard drill chucks or collet holders without adapter hardware.

Key Features

• 0.0635 inch reamer diameter with +0.0002 to -0.0000 inch tolerance for close-tolerance bore finishing
• AlTiN coating extends tool life in hardened and abrasive workpiece materials
• 4-flute straight-flute geometry provides consistent finish and chip clearance in through and blind holes
• Solid carbide construction delivers rigidity and wear resistance at miniature diameters
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for use with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and manual machine tools accepting straight-cylindrical shank reamers in the miniature diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank in a properly sized collet or drill chuck and verify runout before cutting. Power down and de-energize the spindle before inserting or removing the tool. Do not exceed the recommended feed and speed parameters for the workpiece material and reamer diameter to avoid tool deflection or breakage at this miniature size.
