M.a. Ford. 27204950 Chucking Reamer 0.0495 in Solid Carbide

Product Description

The M.A. FORD. 27204950 is a solid carbide chucking reamer engineered for precision hole finishing in tight-tolerance applications. With a reamer diameter of 0.0495 inches and a diameter tolerance of +0.0001 to +0.0003 inches, this tool holds close fits where consistency matters. The straight flute geometry and right-hand cutting direction make it well suited for through-holes and short blind-hole finishing in a variety of workpiece materials. At 1.5 inches overall length with a 3/8-inch flute length, it is compact and stiff - a practical choice for small-diameter reaming where rigidity is critical. Machinists and toolroom technicians install this reamer in drill presses, CNC machining centers, and manual mills via a standard straight shank chuck.

This reamer is sized for micro and small-diameter bore finishing work, covering the 0 to 0.0499 inch diameter range. It fits workflows where a drilled or bored hole needs to be brought to a precise finish diameter with minimal runout. The four-flute design distributes cutting load evenly across the bore wall, improving surface finish and dimensional repeatability. It is uncoated solid carbide, appropriate for applications where coating thickness would interfere with the tight diameter tolerance window.

Key Features

• Solid carbide construction provides rigidity and wear resistance in small-diameter reaming
• Reamer diameter tolerance of +0.0001 to +0.0003 inches supports close-fit hole finishing
• Four straight flutes distribute cutting forces evenly for improved bore surface finish
• Right-hand spiral direction with right-hand cutting for standard CNC and manual machine setups
• Straight shank mounts directly in standard drill chucks or collet holders without adapters
• Uncoated finish preserves dimensional accuracy within the tight tolerance band

Compatibility

Designed as an OEM-style precision cutting tool for use in drill presses, CNC machining centers, and manual milling machines equipped with standard straight-shank chuck or collet toolholding systems capable of accepting this diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a drill chuck or collet holder, ensuring minimal runout before cutting. Always bring the spindle to a complete stop before loading or removing the reamer. Feed rates and speeds should be selected based on workpiece material; consult published carbide reamer speeds-and-feeds references for the material being machined. Do not use this tool as a drill - it is a finishing tool and must be used on pre-drilled or pre-bored holes only.
