Cleveland C25159 Chucking Reamer 0.1015 in Hss

Product Description

The CLEVELAND C25159 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining operations. Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores in ferrous and non-ferrous materials. It carries a wire gauge diameter of #38, equal to 0.1015 inches, and runs a right-hand cut with four straight flutes. The overall length is 3.5 inches with a flute length of 0.875 inches (7/8 inch). The straight shank seats directly in a drill chuck or collet, making it a practical choice for drill press, lathe, or CNC work where close-tolerance hole sizing is required.

This chucking reamer is suited for general machining environments including tool rooms, job shops, and production floors. It handles through-holes and blind-hole reaming in steel, aluminum, brass, and similar machinable materials. The #38 wire gauge size makes it appropriate for small-bore applications where hole geometry and finish tolerances are critical. Machinists, toolroom technicians, and CNC operators are the primary users of this type of reamer.

Key Features

• Wire gauge diameter #38, equal to 0.1015 inches, for small-bore precision reaming
• Four straight flutes for consistent chip evacuation in through-hole applications
• Right-hand cut orientation compatible with standard machine spindle rotation
• High-speed steel construction provides durability across a range of machinable metals
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight shank mounts directly in a drill chuck or collet without an adapter

Compatibility

Designed as a standard chucking reamer for use in drill presses, manual lathes, turret lathes, and CNC machining centers equipped with a drill chuck or straight-shank collet sized for a 0.1015-inch-diameter tool body.

Installation Notes

A licensed machinist or toolroom technician should install and operate this reamer. Power down and de-energize the machine spindle completely before seating or removing the tool from the chuck or collet. Use an appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish quality. Never exceed the recommended feed rate for high-speed steel tooling in the material being machined, and inspect the flutes for wear or chipping before each use.
