M.a. Ford. 27211000 Chucking Reamer No. 35 Solid Carbide

Product Description

The M.A. FORD. 27211000 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built to wire size No. 35 with a decimal diameter of 0.1100 inches, this reamer holds a tolerance of +0.0001 to +0.0003 inches, making it suited for close-tolerance bore work. The 4-flute straight flute geometry provides consistent material removal and surface finish. With an overall length of 2.25 inches and a flute length of 0.625 inches, the compact profile fits standard drill press and CNC machine tool chucks. It is installed and used by machinists, tool-and-die makers, and precision machine shop technicians.

This reamer is used in production and job-shop environments where small-diameter holes require precise sizing after drilling. The straight shank design allows direct mounting in drill chucks, collets, or machine spindles without adapters. Typical applications include finishing through-holes and blind holes in ferrous and non-ferrous metals where dimensional accuracy is critical. The right-hand cutting direction pairs with conventional right-hand spindle rotation. This tool is used in both manual and CNC drilling setups across light manufacturing, aerospace component work, and general precision machining.

Key Features

• Wire size No. 35 diameter — 0.1100 inches decimal equivalent
• Solid carbide construction for rigidity and extended tool life in hard materials
• 4-flute straight flute design for consistent bore finish and chip clearance
• Tight reamer diameter tolerance of +0.0001 to +0.0003 inches for close-fit applications
• Straight shank for direct chuck or collet mounting
• Right-hand cut, right-hand spiral direction — compatible with standard spindle rotation
• Uncoated finish — suitable for use with cutting fluids as required by material

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard drill chucks, collets, and machine spindles accepting straight-shank tooling in the No. 35 wire size diameter range.

Installation Notes

Chucking reamers are installed by machinists in powered drilling or milling equipment. Always power down and lock out the machine spindle before inserting or removing tooling. Secure the straight shank fully within the chuck or collet to the manufacturer-specified engagement depth before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
