Cleveland C25079 Chucking Reamer Size 50 Hss Straight Flute

Product Description

The CLEVELAND C25079 is a straight-flute chucking reamer designed for precision hole finishing in metal components. Built from high-speed steel (HSS) with a bright, uncoated finish, it produces accurate, smooth bores to a finished diameter of 0.0700 inches, corresponding to wire gauge size 50. The reamer features a straight shank for secure chuck mounting and a right-hand cutting direction. With an overall length of 3 inches and a flute length of 0.75 inches across 4 flutes, it is sized for small-bore reaming operations in machine tool setups. Machinists, tool-and-die makers, and precision fabricators are the primary users of this tool.

This chucking reamer is suited for finishing drilled holes in ferrous and non-ferrous metals where tight dimensional tolerances are required. The straight-flute geometry works well in through-hole applications and in materials that produce short, brittle chips. The 0.0700-inch diameter targets small pilot and clearance holes common in instrument components, jigs, fixtures, and precision assemblies. It is intended for use in drill presses, CNC machining centers, lathes, and turret setups where a chuck-held straight-shank tool is appropriate.

Key Features

• 0.0700-inch finished reamer diameter, wire gauge size 50
• High-speed steel construction for durability across general machining applications
• Bright, uncoated finish suitable for use with cutting fluids
• 4 straight flutes with right-hand cut for controlled material removal
• Straight shank for direct chuck mounting without an adapter
• 3-inch overall length with a 0.75-inch flute length for small-bore reach

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems accepting straight-shank tooling in the applicable shank diameter range.

Installation Notes

A licensed machinist or qualified toolroom technician should confirm spindle speed and feed rate before use, as chip load directly affects hole quality and tool life. Always secure the workpiece and ensure the machine spindle is fully stopped before changing or inspecting the reamer. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the cutting edges for wear or chipping before each use, as a worn reamer will produce oversized or out-of-round bores.
