The HARVEY TOOL RSB1660-C3 is a solid carbide chucking reamer designed for precision holemaking in tight-tolerance applications. Built to wire size 19, it produces a finished bore diameter of 0.1660 inches with a tolerance of +0.0002 to 0.0000 inches, making it suitable where dimensional accuracy is critical. The 4-flute, straight-flute geometry with right-hand cutting direction delivers clean, repeatable results. An AlTiN coating extends tool life in abrasive and hard materials. Licensed machinists and toolroom professionals use this reamer in CNC machining centers, drill presses, and manual lathes equipped with a precision chuck.
This reamer is part of the HARVEY TOOL Miniature Reamers series, targeting small-diameter finish reaming in aerospace, medical, automotive, and precision instrument applications. The straight-cylindrical shank at 0.1875 inches (3/16 inch) fits standard collet chucks and drill chucks without adapter hardware. The 3.0-inch overall length and 7/8-inch flute length suit shallow-to-moderate depth finishing passes in ferrous and non-ferrous materials where close-tolerance bore sizing is required.
Designed as an OEM-style precision chucking reamer for use in machining centers, CNC lathes, and drill presses accepting a straight-cylindrical shank. Belongs to the HARVEY TOOL Miniature Reamers series for small-diameter holemaking and threading applications.
Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before loading or changing the tool in the chuck. Seat the shank fully and evenly in a precision collet or drill chuck to minimize runout. Coolant-through is not available on this tool; apply cutting fluid externally as appropriate for the workpiece material.
