M.a. Ford. 27231500 Chucking Reamer 8 Mm Solid Carbide

Product Description

The M.A. FORD. 27231500 is a solid carbide chucking reamer designed to finish-ream holes to a precise 8 mm (0.3150 inch) diameter. With 6 straight flutes, a right-hand cutting direction, and a tolerance of +0.006/+0.012 mm, this reamer delivers consistent, tight-tolerance bore finishes in production and job-shop environments. The straight shank seats directly in a drill chuck or collet holder on most CNC machining centers and manual drill presses. Overall length is 3-1/4 inches (89 mm) with a flute length of 1-1/8 inches (28.50 mm). Machinists and tool-room operators working in ferrous and non-ferrous materials will find the uncoated solid carbide construction suited for demanding, close-tolerance reaming passes.

This reamer is intended for finish-reaming operations where hole size, roundness, and surface finish are critical. Typical applications include precision bore sizing in CNC milling and drilling setups, fixture and jig work, and production runs requiring repeatable 8 mm hole tolerance. The straight-flute geometry works well in through-holes and short blind holes in materials such as aluminum, brass, cast iron, and mild steel. It is sold individually and is suited for shops that require a compact, high-rigidity carbide reamer in the 8 mm diameter class.

Key Features

• 8 mm (0.3150 inch) reamer diameter with +0.006/+0.012 mm tolerance for tight bore sizing
• Solid carbide construction provides rigidity and wear resistance
• 6 straight flutes with right-hand cut for consistent chip evacuation
• Straight shank for direct chuck or collet mounting
• Uncoated finish suitable for use with standard cutting fluids across a range of workpiece materials
• Compact 3-1/4 inch OAL allows use in confined setups and short-reach applications

Compatibility

Designed as a standard straight-shank chucking reamer compatible with drill chucks and collet holders accepting straight-shank tooling in the 8 mm diameter range. No specific machine or model compatibility was provided in the product data.

Installation Notes

Installation is performed by a machinist or tool-room technician. Secure the straight shank firmly in a drill chuck or collet holder, ensuring adequate grip length to prevent slippage under cutting load. Always bring the spindle to a full stop and confirm the workpiece is clamped before tool changes. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.
