M.a. Ford. 27224800 Chucking Reamer 0.248 in Solid Carbide

Product Description

The M.A. FORD. 27224800 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. With a reamer diameter of 0.248 inches and a 4-flute straight flute geometry, it delivers consistent sizing and smooth bore finishes in drilled holes. The straight shank allows direct mounting in standard drill chucks and collet holders. At 3 inches overall length with a 1-inch flute length, this reamer is suited for shallow-to-moderate depth reaming operations where rigidity and dimensional accuracy are critical. It is an uncoated tool intended for use in controlled machining environments.

This chucking reamer is used in machine shop and production environments where precision bore tolerances are required. It is appropriate for use in CNC machining centers, drill presses, and manual lathes. The right-hand cutting direction and straight flute configuration make it a reliable choice for reaming soft to medium-hardness metals. Machinists and tool-and-die professionals typically deploy this reamer as a finishing step after drilling to bring bore diameters to final tolerance. The 0.248-inch diameter corresponds to a dowel pin size of 0.2480 D/P, making it relevant for dowel pin hole preparation.

Key Features

• Solid carbide construction provides rigidity and wear resistance for consistent bore sizing
• 4-flute straight flute design for smooth surface finish and chip clearance
• Right-hand cutting direction with straight shank for standard chuck compatibility
• Uncoated finish suitable for use with cutting fluids in ferrous and non-ferrous applications
• Reamer diameter tolerance of +0.006/+0.012 mm for close-tolerance dowel pin hole finishing
• No coolant-through feature; external coolant or cutting oil application required

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems accepting straight shank tooling in the 0.248-inch diameter range. Suited for dowel pin hole reaming to 0.2480 D/P specification per the Series 272 product line.

Installation Notes

Installation and operation of this reamer should be performed by a qualified machinist. Secure the straight shank firmly in a properly sized collet or drill chuck before use, and verify runout before cutting. Always apply appropriate cutting fluid or oil during reaming to extend tool life and maintain bore finish quality. Do not exceed recommended feed rates for solid carbide tooling, as carbide is brittle and susceptible to chipping under lateral shock loads.
