M.a. Ford. 27217720 Chucking Reamer 4.5 Mm Solid Carbide

Product Description

The M.A. FORD. 27217720 is a solid carbide chucking reamer designed for precision hole finishing in metal and engineered materials. With a 4.5 mm (0.1772 inch) reamer diameter, it delivers a tight diameter tolerance of +0.005/+0.010 mm, making it well suited for applications that require consistent, accurate bore sizing. The straight flute geometry and right-hand cutting direction provide clean, controlled stock removal. This reamer is sold individually and is intended for use by machinists and tool-and-die professionals working with CNC machining centers, drill presses, and manual mills.

This reamer is appropriate for general-purpose reaming operations in production and job-shop environments. It handles hole finishing in ferrous and non-ferrous metals where close tolerances are required. The straight shank allows direct chuck mounting in standard toolholders. With an overall length of 2-3/4 inches (76 mm) and a flute length of 7/8 inch (22 mm), it fits compact tooling setups and shallow-to-moderate depth bores. No coolant-through capability means it is best suited for operations where flood or mist coolant is applied externally.

Key Features

• 4.5 mm (0.1772 inch) diameter with a precision tolerance of +0.005/+0.010 mm for accurate bore sizing
• Solid carbide construction for superior wear resistance and rigidity versus high-speed steel
• Straight flute geometry with right-hand spiral direction for smooth, stable cutting action
• Straight shank design for direct mounting in standard drill chucks and toolholders
• 4-flute configuration balances chip evacuation with surface finish quality
• Uncoated finish suitable for a wide range of general-purpose reaming applications

Compatibility

Designed as a general-purpose chucking reamer compatible with standard straight-shank toolholders on CNC machining centers, manual mills, and drill presses where a 4.5 mm bore diameter and straight shank are specified.

Installation Notes

Installation and use should be performed by a qualified machinist. Secure the straight shank firmly in a chuck or collet before operation and verify runout is within acceptable limits prior to cutting. Apply appropriate external coolant or cutting fluid to extend tool life and maintain bore quality. Never exceed the recommended feed and speed parameters for solid carbide tooling in the workpiece material being machined.
