Cleveland C25151 Chucking Reamer Size 40 Hss Straight Flute

Product Description

The CLEVELAND C25151 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel with a bright uncoated finish, this reamer produces accurate, smooth bores at a nominal diameter of 0.0980 inches (wire size 40). It features a 4-flute straight configuration and a straight shank for secure chuck retention. With an overall length of 3.5 inches and a flute length of 0.875 inches, the C25151 is sized for close-tolerance reaming on small-diameter holes typical in toolroom, maintenance, and production machining environments.

This chucking reamer is suited for use in drill presses, lathes, CNC machining centers, and manual milling machines where repeatable hole sizing is required. It is appropriate for right-hand cutting operations on ferrous and non-ferrous materials. The straight flute geometry makes it well suited for reaming through-holes in softer metals and general-purpose materials where chip clearance is straightforward. Machinists, toolroom technicians, and maintenance professionals working with wire-gauge size holes in the 0.0500 to 0.0999 inch diameter range will find this reamer a direct-fit selection for standard finish-reaming tasks.

Key Features

• Nominal reamer diameter of 0.0980 inches, wire gauge size 40
• High-speed steel construction for durability across ferrous and non-ferrous materials
• 4-flute straight configuration for consistent chip evacuation in through-hole applications
• Bright uncoated finish, ready for use without additional surface treatment
• Straight shank for direct chuck mounting on standard drill presses, lathes, and machining centers
• Right-hand cutting direction, compatible with conventional machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use with standard drill chucks and collet holders that accept straight-shank tooling sized for small-diameter wire-gauge reamers.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a drill chuck or collet before operation and verify runout is within acceptable tolerance before cutting. Power down the machine spindle completely before inserting or removing the reamer. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
