M.a. Ford 27219900 Chucking Reamer No. 8 Solid Carbide

Product Description

The M.A. FORD 27219900 is a solid carbide chucking reamer designed to produce accurate, smooth-bore holes in precision machining applications. Built to No. 8 wire size (0.1990 inches), it features a 4-flute straight flute geometry with right-hand cut and right-hand spiral direction. The diameter tolerance of +0.0001/+0.0003 inches makes it well suited for close-tolerance bore finishing. With a 3.0-inch overall length and a 1-inch flute length, this reamer fits standard drill chuck setups and is used by machinists and tooling professionals across production and job-shop environments.

This chucking reamer is intended for finishing pre-drilled holes to a precise diameter in a range of workpiece materials. It is appropriate for use in manual drill presses, CNC machining centers, and turret lathes where chuck mounting is standard. The straight shank allows direct clamping in a keyed or keyless chuck without the need for a collet adapter. Typical applications include precision bore finishing in metalworking operations where tight dimensional control is required. The uncoated solid carbide construction performs in dry or lightly lubricated cutting conditions.

Key Features

• Right-hand cut and right-hand spiral direction
• Straight shank for direct chuck mounting without additional adapters
• Uncoated finish suitable for dry or minimally lubricated cutting operations

Compatibility

Designed as an OEM-style precision chucking reamer compatible with standard drill chuck setups in the No. 8 wire size range (0.1500 to 0.1999 inches), part of the M.A. FORD Series 272 reamer line.

Installation Notes

Installation and use should be performed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and locked out before inserting or removing the reamer from the chuck. Confirm runout is within acceptable limits before reaming to avoid compromising bore tolerance. Always pre-drill or bore the hole close to final size before using a chucking reamer to achieve the specified tolerance.
