Harvey Tool RSB1260 Chucking Reamer 0.1260 in Carbide

Product Description

The HARVEY TOOL RSB1260 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a 0.1260-inch reamer diameter and a diameter tolerance of +0.0000 to -0.0002 inches, this tool holds the close tolerances required for dowel holes, bearing bores, and similar precision fits. The 4-flute, straight-flute geometry and right-hand cutting direction make it well suited for use in CNC machining centers, drill presses, and manual lathes. At 3 inches overall length with a 0.75-inch flute length, the RSB1260 falls within the miniature reamer series, covering diameters in the 0.1000 to 0.1499-inch range. Installation is handled by machinists and toolroom technicians working in metalworking and manufacturing environments.

This reamer is intended for precision finish reaming of small-diameter bores in metalworking and manufacturing settings. The miniature reamer series addresses applications where standard-size reamers cannot reach required diameters. The straight-cylindrical shank seats directly into standard collet chucks or drill chucks without additional adapters. The bright, uncoated carbide finish is appropriate for use on a range of materials including steel, aluminum, and brass. It is sold individually and is suited for both production and toolroom use where repeatable, tight-tolerance hole finishing is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter reaming
• 0.1260-inch reamer diameter with +0.0000 to -0.0002-inch tolerance for precision bore finishing
• 4-flute straight-flute geometry with right-hand cutting direction
• 0.75-inch flute length and 3-inch overall length for compact reach
• Straight-cylindrical shank compatible with standard collet and drill chucks
• Bright, uncoated finish — no coating buildup to affect finished bore diameter

Compatibility

Part of the HARVEY TOOL Miniature Reamers series, covering the 0.1000 to 0.1499-inch reamer diameter range. Designed for use in CNC machining centers, drill presses, and lathes equipped with standard collet or drill chuck toolholding accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists or toolroom technicians. Ensure the workpiece is securely fixtured and the spindle is brought to the appropriate speed and feed for the material being reamed before engaging the tool. Power down and lock out the machine before changing tooling. Avoid using a reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
