M.a. Ford. 27206890 Chucking Reamer 1.75 Mm Solid Carbide

Product Description

The M.A. FORD. 27206890 is a solid carbide chucking reamer designed for precision hole finishing in machined components. Built to a 1.75 mm diameter (0.0689 decimal inch), it holds a reamer diameter tolerance of +0.004/+0.008 mm, making it suitable for applications where bore accuracy and surface finish are critical. The straight flute geometry and right-hand cutting direction suit through-hole and short blind-hole reaming operations. With an overall length of 51 mm (approximately 1.75 inches) and a flute length of 12.5 mm (0.5 inches), this tool is sized for small-bore work in precision machining environments. Machinists and toolroom professionals install this reamer in CNC machining centers, drill presses, or manual mills using a standard straight-shank chuck.

This reamer is intended for small-diameter bore finishing in metals and engineering plastics. It fits production and toolroom applications where hole diameter control in the 1.00 mm to 2.00 mm range is required. The uncoated solid carbide construction is well-matched to non-ferrous metals, aluminum alloys, brass, and similar materials where carbide edge retention provides consistent sizing across multiple parts. It is sold individually and is appropriate for shops requiring a single precision tool at this diameter.

Key Features

• Solid carbide construction for edge rigidity and dimensional consistency in small-bore reaming
• 1.75 mm (0.0689 inch) diameter with a tight tolerance of +0.004/+0.008 mm
• Straight flute, right-hand cut geometry suited to through-hole and short blind-hole applications
• 4-flute design for improved surface finish and chip clearance
• Straight shank compatible with standard drill chucks and collet holders
• Uncoated finish — no coating buildup that could affect critical diameter dimensions

Compatibility

Designed as an OEM-style precision reamer for use in standard straight-shank chuck or collet setups on CNC machining centers, drill presses, and manual milling machines handling small-bore hole finishing in the 1.00 mm to 2.00 mm diameter range.

Installation Notes

This reamer is installed by a machinist or toolroom professional into a straight-shank drill chuck or collet holder rated for the shank diameter. The machine spindle must be stopped and secured before tool changes. Use appropriate cutting fluid or coolant for the workpiece material even though coolant-through is not available on this tool. Do not use this reamer to remove stock beyond what is appropriate for a finishing pass — pre-drill or bore the hole to within a few hundredths of a millimeter before reaming to final size.
