M.a. Ford. 27206900 Chucking Reamer 0.069 in Solid Carbide

Product Description

The M.A. FORD. 27206900 is a solid carbide chucking reamer designed for precision hole finishing in demanding machining applications. With a reamer diameter of 0.069 inches and a tight tolerance of +0.0001/+0.0003 inches, this tool delivers consistent, accurate bore sizing in a single pass. The straight flute geometry and right-hand cutting direction make it well suited for through-hole and blind-hole reaming in materials where chip control and surface finish are critical. At 1.75 inches overall length with a 0.5-inch flute length and straight shank, it fits standard chuck and collet setups used on drill presses, CNC machining centers, and manual lathes.

This chucking reamer is intended for precision hole finishing in metalworking environments, including tool and die shops, machine shops, and production floor operations. The 0.069-inch diameter places it in the small-bore range, making it appropriate for finishing pilot holes, dowel pin bores, and precision fit holes in ferrous and non-ferrous workpieces. The uncoated solid carbide construction provides rigidity and wear resistance in harder materials. Licensed machinists and CNC operators are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• Reamer diameter tolerance of +0.0001/+0.0003 inches for precise bore sizing
• Straight flute design with right-hand cut for clean chip evacuation
• 4-flute configuration provides a stable cutting action and improved surface finish
• Straight shank fits standard chucks and collets without adapters
• Uncoated finish maintains consistent diameter accuracy without coating buildup

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard chuck or collet toolholders on drill presses, CNC machining centers, and manual lathes accepting straight-shank tooling in the small-bore diameter range.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with precision hole-finishing operations. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Verify chuck or collet runout before use, as excessive runout will negatively affect bore tolerance and surface finish. Do not use this reamer to remove stock beyond its rated tolerance range.
