Harvey Tool RSB1875-C3 Carbide Chucking Reamer 3/16 in

Product Description

The HARVEY TOOL RSB1875-C3 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.1875 inches and a tight tolerance of +0.0002 to -0.0000 inches, this tool delivers consistent, accurate bore sizing in a single pass. The AlTiN coating provides heat resistance and extended tool life when cutting ferrous and hardened materials. Four straight flutes with right-hand cutting direction make it well suited for CNC machining centers, lathes, and drill presses. Machinists and toolroom professionals install this reamer in standard chucks or collets to bring pre-drilled holes to final finished diameter.

The RSB1875-C3 belongs to the Harvey Tool Miniature Reamers series, covering reamer diameters in the 0.1500 to 0.1999 inch range. It is used in precision holemaking operations where tight tolerances and fine surface finish are required. Typical applications include fixture-making, aerospace components, mold and die work, and any production environment where undersized bored holes must be brought to exact specification. The 4-inch overall length and 1-inch flute length provide adequate reach for most shallow-to-moderate depth holes in this size range.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating extends tool life and reduces heat buildup at the cutting edge
• Diameter tolerance of +0.0002 to -0.0000 inches for precise, repeatable hole sizing
• Four straight flutes with right-hand cutting direction for smooth chip evacuation in through and blind holes
• Straight cylindrical shank for direct mounting in drill chucks, collets, or reamer holders
• Part of the Miniature Reamers series, covering the 0.1500 to 0.1999 inch diameter range

Compatibility

Designed as an OEM-style precision chucking reamer for use in CNC machining centers, manual lathes, and drill presses equipped with standard chucks or collets capable of holding a straight cylindrical shank in the 3/16 inch diameter class.

Installation Notes

This reamer is installed by qualified machinists in a machine tool spindle using a collet, drill chuck, or dedicated reamer holder. Always ensure the workpiece is securely clamped and the pre-drilled or bored hole is sized appropriately undersize before reaming. Use cutting fluid compatible with the workpiece material and the AlTiN coating to maximize tool life. Do not use this tool for interrupted cuts or lateral milling passes, as chucking reamers are designed for axial feed only.
