M.a. Ford. 27217320 Chucking Reamer 4.40mm Solid Carbide

Product Description

The M.A. FORD. 27217320 is a solid carbide chucking reamer designed for precision hole finishing in metal components. With a 4.40mm reamer diameter (0.1732 decimal inch) and a 70.00mm overall length, this tool delivers accurate, repeatable bore sizing in machine shop and production environments. The bright, uncoated solid carbide construction provides rigidity and wear resistance in a compact package. Machinists and tool-and-die professionals use this reamer where tight diameter tolerances and smooth bore finish are required in CNC machining centers and drill press setups.

This reamer fits production and job shop applications where 4.00mm to 5.00mm diameter hole finishing is required. The 22.00mm flute length provides adequate chip clearance for the bore depth typical of small-diameter precision work. Right-hand cutting direction and straight flute geometry suit most standard through-hole and blind-hole reaming operations in steel, aluminum, brass, and similar machinable materials. It is sold and shipped individually with a minimum order quantity of one piece, making it practical for both production restocking and single-tool replacement.

Key Features

• Solid carbide construction for rigidity and extended tool life in precision reaming
• 4.40mm (0.1732 inch) diameter with a tolerance of plus 0.005 to plus 0.010mm over nominal
• Straight-cylindrical shank for direct chuck or collet holding without adapters
• 4-flute, straight flute, right-hand cutting geometry for smooth, consistent bore finish
• Bright, uncoated finish suitable for use with standard cutting fluids
• Series 272 designation for straightforward reorder and tooling inventory management

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, manual drill presses, and lathe tailstock applications requiring 4.00mm to 5.00mm diameter hole finishing with a straight-cylindrical shank interface.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Secure the straight-cylindrical shank in a precision collet, drill chuck, or reamer holder that is concentric and free of runout before use. Always bring the spindle to a complete stop and confirm the workpiece is firmly fixtured before engaging the reamer. Do not use this tool as a drill; reamers require a pre-drilled or bored pilot hole sized appropriately undersized to the finished diameter.
