Harvey Tool RSB0615-C3 Chucking Reamer 0.0615in Carbide

Product Description

The HARVEY TOOL RSB0615-C3 is a solid carbide chucking reamer designed to finish-ream precision holes to tight tolerances in small-diameter applications. At 0.0615 inches in diameter with a 4-flute straight geometry, it holds a reamer diameter tolerance of +0.0002 to -0.0000 inches, making it well-suited for exacting fit requirements in close-tolerance bores. The AlTiN coating extends tool life in harder workpiece materials by providing thermal and oxidation resistance at the cutting edge. Machinists and toolroom operators use this reamer in CNC machining centers, drill presses, and manual mills where repeatable hole sizing is critical.

This reamer is part of the HARVEY TOOL Miniature Reamers series, built for small-diameter holemaking in precision machining environments. The straight flute design and straight cylindrical shank allow it to seat reliably in standard collet chucks and drill chucks. It is suited for use in ferrous and non-ferrous materials where a smooth, accurate bore finish is required after drilling. Typical applications include instrument components, medical device tooling, electronics hardware, and other small-part manufacturing where sub-0.1-inch hole diameters demand tight size control.

Key Features

• Solid carbide construction provides rigidity and wear resistance in precision reaming operations
• AlTiN coating improves thermal resistance and extends tool life in harder materials
• 4-flute straight geometry delivers a consistent, smooth bore finish
• Diameter tolerance of +0.0002 to -0.0000 inches supports tight-fit hole specifications
• Straight cylindrical shank is compatible with standard collet and drill chucks
• Miniature series sizing at 0.0615 inches diameter covers the 0.0500 to 0.0999 inch range

Compatibility

Designed as an OEM-style precision reamer for use in standard chucking setups on CNC machining centers, knee mills, and drill presses where a straight cylindrical shank interface is used. No specific machine model compatibility was provided.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with small-diameter rotary cutting tools. Secure the straight shank firmly in a collet or drill chuck with appropriate runout control before operation, as excessive runout at this diameter range will directly affect bore size and finish. Power down and de-energize the machine spindle completely before tool changes. Consult the machine tool builder specifications and applicable shop safety standards for proper feed and speed selection with carbide reamers in the miniature diameter range.
