M.a. Ford 27206450 Chucking Reamer 0.0645 in Solid Carbide

Product Description

The M.A. FORD 27206450 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance applications. Built to Series 272 specifications, this reamer holds a diameter tolerance of +0.0001 to +0.0003 inches, making it well-suited for work where hole size accuracy is critical. The 4-flute straight configuration and right-hand cutting direction deliver a clean, consistent finish in a variety of materials. At 1.5 inches overall length with a 3/8-inch flute length, this tool is sized for small-diameter work requiring tight control. The straight-cylindrical shank seats directly in a standard chuck for quick, secure setup.

This reamer is used in precision machining environments where small-bore hole finishing is required. Typical applications include finishing drilled or bored holes in metal components where tight dimensional tolerances are specified. The 0.0645-inch diameter targets small-bore work in industries such as aerospace, medical device manufacturing, and general precision machining. It is installed by machinists on CNC machining centers, drill presses, or manual milling machines using a standard chuck.

Key Features

• Solid carbide construction provides hardness and wear resistance for precision reaming
• Diameter tolerance of +0.0001 to +0.0003 inches ensures consistent, repeatable hole sizing
• 4-flute straight design for clean, smooth finishes in small-diameter bores
• Right-hand cutting direction with right-hand spiral for standard machining setups
• Bright/uncoated finish - no coating interference on critical diameter
• Straight-cylindrical shank for direct chuck mounting with no adapter required

Compatibility

Designed as an OEM-style solid carbide chucking reamer in the M.A. FORD Series 272 line, suited for standard chuck-mounted reaming of 0.0645-inch diameter holes.

Installation Notes

Installation is performed by machinists using a standard drill chuck or collet chuck sized for the straight-cylindrical shank diameter. Ensure the spindle and workpiece are properly secured before engaging the reamer. Recommended practice is to ream after drilling, taking a light finishing pass to bring the hole to final tolerance. Follow applicable shop safety standards and machine guarding requirements during operation.
