Harvey Tool RSB0980 Chucking Reamer Wire Size 40

Product Description

The HARVEY TOOL RSB0980 is a solid carbide chucking reamer designed for precision hole finishing in small-diameter applications. With a wire gauge size 40 diameter of 0.0980 inches (2.50 mm), this reamer holds a tight tolerance of +0.0000 to -0.0002 inches, making it well-suited for work requiring consistent, accurate bore sizing. The 4-flute straight configuration supports smooth cutting action, and the bright uncoated carbide surface is appropriate for a range of workpiece materials. At 2.5 inches overall length with an 11/16 inch flute length, the RSB0980 fits standard precision toolholders and chucks used in CNC machining centers, drill presses, and manual machine tools.

This reamer is part of the HARVEY TOOL Miniature Reamers series, targeting applications where small bore diameters demand high dimensional control. It is used in holemaking and threading operations across aerospace, medical device, electronics, and general precision machining environments. The straight shank accepts standard collet chucks and drill chucks without adapter hardware, simplifying setup in both production and job-shop scenarios. No coolant-through capability means it is best suited for conventional flood coolant or dry cutting setups.

Key Features

• Wire size 40 diameter: 0.0980 inches (2.50 mm) for miniature bore finishing
• Tight diameter tolerance of +0.0000 to -0.0002 inches for repeatable hole sizing
• 4-flute straight configuration for smooth, stable cutting action
• Solid carbide construction for wear resistance and dimensional stability
• Bright uncoated finish suitable for a broad range of workpiece materials
• Straight-cylindrical shank for direct mounting in standard collet or drill chucks

Compatibility

Designed as an OEM-style miniature chucking reamer for use in standard straight-shank toolholders and collet chucks sized to accept a 0.0980-inch shank diameter in CNC and manual machine tool applications.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is properly secured before mounting or removing the reamer. Use appropriate cutting fluid or flood coolant as recommended for the workpiece material, and verify spindle speed and feed rate against manufacturer tooling data before operation. Inspect the cutting edges for chipping before each use, as carbide tooling is brittle and sensitive to improper handling.
