M.a. Ford. 27209400C Chucking Reamer 3/32 in Solid Carbide

Product Description

The M.A. FORD. 27209400C is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built to Series 272 specifications, it features a 3/32 inch (0.0940 inch decimal) diameter with a reamer diameter tolerance of +0.0001 to +0.0003 inches, ensuring accurate, repeatable results in production or toolroom environments. The TiCN coating improves surface hardness and wear resistance for extended tool life. With a straight-cylindrical shank and 4 straight flutes in a right-hand cutting direction, this reamer is suited for use in CNC machining centers, drill presses, and manual lathes. Machinists and toolroom technicians are the primary installers of this tool.

This chucking reamer is intended for small-diameter precision reaming in metalworking applications where hole size and surface finish are critical. The 2 inch overall length and 1/2 inch flute length make it appropriate for shallow-hole reaming operations in ferrous and non-ferrous metals. It is classified as a modified standard item under M.A. FORD. Series 272. No coolant-through capability is present, so external coolant or cutting fluid should be applied as needed during operation.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• TiCN coating enhances surface hardness and extends tool life
• Diameter tolerance of +0.0001 to +0.0003 inches for tight-tolerance hole finishing
• 4 straight flutes with right-hand cutting direction for smooth material removal
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• No coolant-through design simplifies setup in standard machine tool configurations

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard drill chucks and collet holders accepting a straight-cylindrical shank at 3/32 inch diameter; suitable for CNC and manual machine tool setups requiring small-diameter precision reaming.

Installation Notes

This tool should be installed and operated by qualified machinists or toolroom technicians familiar with small-diameter carbide tooling. Secure the shank firmly in a precision collet or drill chuck before use to minimize runout. Carbide tooling is brittle and should not be subjected to side loads or impact during handling or operation. Apply appropriate cutting fluid externally when reaming to manage heat and chip evacuation, as this tool does not include coolant-through capability.
