Harvey Tool RSB2500-C3 Chucking Reamer Letter E Carbide

Product Description

The HARVEY TOOL RSB2500-C3 is a solid carbide chucking reamer sized at Letter E (0.2500 inches diameter) for precision hole finishing in machining applications. Built to the Miniature Reamers series, it features a straight-cylindrical shank and six straight flutes with right-hand cutting action. The AlTiN coating improves wear resistance and tool life when running in ferrous and hardened materials. Overall length is 4 inches with a flute length of 1-1/8 inches. Diameter tolerance is held to +0.0002 to 0.0000 inches, making it suitable for close-tolerance bore finishing where dimensional accuracy is critical. Machinists and tool-and-die professionals use this reamer in drill press, lathe, or CNC machining center applications.

This reamer is designed for reaming pre-drilled or bored holes to a precise 0.2500 inch finished diameter. It fits standard chucking setups and is well suited for finishing through-holes and blind holes in ferrous metals, stainless steel, aluminum, and similar materials where surface finish and dimensional control are required. The compact 4-inch overall length makes it appropriate for work on smaller workpieces and close-quarters fixtures typical in miniature component machining.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating extends tool life in ferrous and hardened workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, accurate bore finishing
• Diameter tolerance of +0.0002 to 0.0000 inches for close-tolerance hole sizing
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Miniature Reamers series — optimized for small-diameter precision work

Compatibility

Designed as an OEM-style replacement and standard chucking reamer for use in any machine tool equipped with a drill chuck or collet system accepting a straight-cylindrical shank at the corresponding shank diameter.

Installation Notes

Chucking reamers are installed and operated by qualified machinists following standard shop safety practices. Secure the shank firmly in a drill chuck or precision collet before use and verify runout before cutting. Power down and de-energize the machine spindle completely before tool changes. Do not attempt to use a chucking reamer as a drill — always pre-drill or bore the hole to the appropriate undersize before reaming.
