Harvey Tool RSB1570 Chucking Reamer 0.157 in Solid Carbide

Product Description

The HARVEY TOOL RSB1570 is a solid carbide chucking reamer designed to finish-ream holes to a precise diameter of 0.1570 inches (Wire Size 22). It features 4 straight flutes with a right-hand cutting direction and an uncoated bright finish. With an overall length of 3 inches and a flute length of 0.875 inches, this reamer is built for tight-tolerance holemaking in small-diameter applications. The straight-cylindrical shank measures 0.1875 inches in diameter. Licensed machinists, tool-and-die makers, and precision metalworking shops are the primary users of this tool.

This miniature reamer is suited for precision reaming operations where hole diameter tolerances must be held within a very tight range. The diameter tolerance is +0.0000 to -0.0002 inches, making it appropriate for close-fit dowel holes, instrument components, and other small-bore finish operations in production and job-shop environments. Its compact geometry fits machine tool chucks used on CNC machining centers, manual mills, and drill presses equipped for small-diameter tooling.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision holemaking
• 0.1570 inch finished reamer diameter (Wire Size 22 / 4.00 mm equivalent)
• Tight diameter tolerance of +0.0000 to -0.0002 inches for close-fit applications
• 4 straight flutes with right-hand cutting direction
• Bright uncoated finish suitable for a wide range of workpiece materials
• Straight-cylindrical shank (0.1875 inches) for standard chuck compatibility
• Part of the Harvey Tool Miniature Reamers series for small-diameter applications

Compatibility

Designed as an OEM-style precision reamer for use in standard machine tool chucks accepting a 0.1875-inch straight-cylindrical shank, typical of CNC machining centers, knee mills, and drill presses used in precision metalworking applications.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with precision holemaking practices. Ensure the machine spindle and chuck are clean and properly aligned before seating the shank to avoid runout that could compromise hole tolerance. Power down the machine and de-energize all controls before changing tooling. Do not use this reamer as a drill — pre-drill or bore the hole to the recommended undersize before reaming.
