M.a. Ford. 27231150 Carbide Chucking Reamer 0.3115 in

Product Description

The M.A. FORD. 27231150 is a solid carbide chucking reamer designed to bring bored or drilled holes to a precise finished diameter. With a 0.3115-inch cutting diameter and a tight tolerance of +0.0001 to +0.0003 inches, this tool delivers the dimensional accuracy required for close-tolerance fit applications. The 6-flute, straight-flute geometry produces a clean, consistent finish along the 1-1/8-inch flute length. The straight shank mounts directly into standard drill chucks or collet holders. Right-hand cutting direction and an uncoated solid carbide body make this reamer well suited for ferrous and non-ferrous materials in production or toolroom environments.

This reamer is used in machining operations where hole finish and diameter tolerance are critical, such as bearing seat preparation, pin fit bores, and precision assembly applications. It is sized at 0.3115 inches, which falls in the 0.3000 to 0.3499 inch diameter range of the M.A. FORD. Series 272 line. Machinists and tool-and-die technicians working on manual mills, CNC machining centers, or drill presses will find this tool appropriate for through-hole reaming in moderate-depth applications.

Key Features

• Solid carbide construction provides rigidity and wear resistance for consistent hole sizing
• Diameter tolerance of +0.0001 to +0.0003 inches supports close-tolerance fit requirements
• 6-flute straight-flute geometry for smooth finish and chip clearance
• Right-hand cutting direction with right-hand spiral for standard spindle operation
• Straight shank compatible with standard drill chucks and collet holders
• Uncoated finish — suitable for use in a broad range of workpiece materials

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet-style toolholders accepting a straight shank; part of the M.A. FORD. Series 272 reamer line for the 0.3000 to 0.3499 inch diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with cutting tool setup and speeds-and-feeds selection. Ensure the workpiece and spindle are fully secured and the machine is at a safe stop before mounting or removing the tool. Match spindle speed and feed rate to the workpiece material and hole depth to avoid tool deflection or chipping of the carbide flutes. Do not reverse spindle direction under load, as this tool is designed for right-hand cutting only.
