M.a. Ford. 27231350 Chucking Reamer 0.3135 in Solid Carbide

Product Description

The M.A. FORD. 27231350 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built to a 0.3135-inch diameter with a right-hand cutting direction and six straight flutes, it delivers tight, repeatable tolerances of +0.0001 to +0.0003 inches over nominal size. The straight shank allows it to seat directly in standard drill chucks or collet holders. With a 3.25-inch overall length and a 1.125-inch flute length, it is sized for short-to-medium depth through-hole and blind-hole reaming. Licensed machinists and tool-and-die professionals are the primary installers of this tool in production and maintenance environments.

This reamer suits applications where bore finish and dimensional accuracy are critical, including fitting dowel pin holes, bearing bores, and precision assembly clearances. It is suited for use in CNC machining centers, manual mills, and drill presses across general metalworking, mold-and-die, and aerospace maintenance shops. The uncoated solid carbide construction makes it appropriate for cast iron, aluminum, brass, and similar non-ferrous or moderate-hardness ferrous materials where carbide wear resistance outperforms high-speed steel without the added cost of a coating.

Key Features

• Solid carbide construction provides superior wear resistance and dimensional stability compared to high-speed steel
• Six straight flutes deliver smooth, consistent chip evacuation and finish quality in through-hole and blind-hole applications
• Right-hand spiral and right-hand cutting direction for standard clockwise spindle operation
• Diameter tolerance of +0.0001 to +0.0003 inches over nominal ensures press-fit and slip-fit bore accuracy
• Straight shank compatible with standard drill chucks and precision collet holders
• Uncoated finish suits a wide range of base materials without coating interaction concerns

Compatibility

Designed as a straight-shank chucking reamer for use in standard drill chucks and collet-style toolholders on CNC machining centers, manual milling machines, and drill presses. Specific machine compatibility is determined by shank diameter and chuck capacity.

Installation Notes

Installation and operation of this reamer should be performed by a qualified machinist familiar with speeds, feeds, and cutting fluid requirements for solid carbide tooling. Ensure the workpiece is securely fixtured and the spindle is confirmed to be running true before engaging the reamer, as runout will damage carbide flutes and compromise bore tolerance. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life. Inspect flutes for chipping before each use and do not force the tool through an undersized pre-drilled hole.
