M.a. Ford. 27209840 Chucking Reamer 2.5 Mm Carbide

Product Description

The M.A. FORD. 27209840 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining operations. With a 2.5 mm (0.0984 inch) cutting diameter and a reamer diameter tolerance of +0.004/+0.008 mm, this tool produces accurate, repeatable bore dimensions in a single pass. The straight flute geometry and right-hand cutting direction make it well-suited for through-holes in a range of materials. At 2.25 inches overall length with a 0.625 inch flute length, it fits standard chucks and collets on CNC machining centers, drill presses, and manual mills. No coating is applied, keeping the carbide substrate fully exposed for inspection and resharpening. Machinists, tool-and-die makers, and precision machine shops are the primary users.

This chucking reamer is intended for finish-reaming operations where dimensional accuracy and surface finish are critical. The straight shank seats directly in a drill chuck or collet holder without additional tooling adapters. With four flutes and a right-hand spiral direction, the tool maintains stable cutting action in ferrous and non-ferrous materials. It is sized for applications requiring a nominal 2.5 mm finished bore diameter, commonly encountered in fixture work, jig drilling, dowel pin fitting, and precision component manufacturing. The compact overall length suits short-reach applications on standard machining equipment.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 2.5 mm cutting diameter with a tight tolerance of +0.004/+0.008 mm for accurate bore sizing
• Four straight flutes with right-hand cutting direction for stable, consistent material removal
• Straight shank compatible with standard drill chucks and collet holders
• Uncoated carbide substrate allows easy inspection and supports resharpening
• No coolant-through requirement simplifies setup on standard equipment

Compatibility

Designed as an OEM-style precision cutting tool for use in standard drill chucks and collet holders on CNC machining centers, drill presses, and manual milling machines capable of accepting a straight shank reamer in the 2.5 mm diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Secure the straight shank firmly in a drill chuck or collet before operation, and verify runout with an indicator before cutting. Power down and lock out the machine before changing or inspecting tooling. Reaming feeds and speeds should follow the tool manufacturer guidelines for the specific workpiece material to avoid oversize bores or premature tool wear.
