Cleveland C25128 Chucking Reamer Wire Size 43 Hss

Product Description

The CLEVELAND C25128 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Made from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces tight-tolerance bores in a wire size 43 diameter of 0.0890 inches. With an overall length of 3 inches and a straight shank, it seats securely in drill chucks and collet-style holders. Four right-hand-cut flutes provide clean, consistent material removal on through and blind holes. This tool is used by machinists and toolroom technicians where accurate hole sizing is required before press-fitting pins, bushings, or fasteners.

The C25128 is suited for general-purpose reaming in light-to-medium production and repair work. Its straight shank accepts standard drill chucks on benchtop drill presses, CNC machining centers, and manual mills. The 3/4-inch flute length accommodates shallow-to-moderate material depths typical of small-diameter hole finishing. High-speed steel construction handles a range of ferrous and non-ferrous workpiece materials at appropriate cutting speeds and feeds.

Key Features

• Wire size 43 diameter: 0.0890 inches for precise small-hole finishing
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Straight flute geometry for smooth, consistent cutting action
• Four right-hand-cut flutes for balanced material removal
• Bright, uncoated finish — ready for use with cutting fluid as required
• Straight shank fits standard drill chucks and collet holders

Compatibility

Designed as a standard straight-shank chucking reamer compatible with drill chucks and collet holders sized for the straight shank diameter on manual drill presses, knee mills, and CNC machining centers.

Installation Notes

This reamer is installed and operated by machinists or toolroom technicians. Secure the straight shank firmly in a drill chuck or collet before use, and verify runout is within acceptable limits for the required hole tolerance. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never use a reamer to remove large amounts of material — leave only 0.001 to 0.005 inches of stock for finishing, based on your process requirements and material specifications.
