Cleveland C25380 Chucking Reamer 0.1935 in Hss

Product Description

The CLEVELAND C25380 is a straight-flute chucking reamer machined from high-speed steel and designed for precision hole finishing in metalworking operations. The reamer measures 0.1935 inches in diameter, placing it in the No. 10 wire gauge size range. With an overall length of 5 inches and a flute length of 1.25 inches, it is sized for use in drill presses, lathes, and CNC machining centers. Six flutes and a right-hand cutting direction deliver smooth, consistent material removal. The bright, uncoated finish is standard for general-purpose HSS reamers used across a wide range of ferrous and non-ferrous materials.

This chucking reamer is suited for production and maintenance machining environments where close-tolerance bore finishing is required. The straight shank allows direct mounting in standard drill chucks or collet holders. It is appropriate for machine shops, maintenance facilities, and precision fabrication operations working with materials that accept HSS tooling at moderate cutting speeds.

Key Features

• 0.1935 inch cutting diameter — No. 10 wire gauge size
• High-speed steel construction for durability across common ferrous and non-ferrous workpieces
• 6 straight flutes with right-hand cut for consistent, chatter-resistant bore finishing
• 5 inch overall length with 1.25 inch flute length
• Straight shank for direct chuck or collet mounting
• Bright, uncoated finish — no coating degradation risk during regrinding

Compatibility

Designed as an OEM-style replacement or standard tooling addition for machine shop applications requiring a No. 10 wire gauge straight-flute chucking reamer with a straight shank.

Installation Notes

This reamer is installed by a machinist in a drill press, lathe tailstock, or CNC spindle using a standard drill chuck or collet rated for the shank diameter. Ensure the workpiece is securely fixtured and the spindle is at the correct RPM for the material before engaging the reamer. Always apply appropriate cutting fluid to extend tool life and improve bore finish. Inspect the reamer for wear or chipping before each use.
