Cleveland C25397 Chucking Reamer 0.2010 in Hss Straight Flute

Product Description

The CLEVELAND C25397 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores to a diameter of 0.2010 inches. It features six flutes with a right-hand cut, delivering clean chip evacuation and consistent surface finish. The straight shank is compatible with standard drill chucks and collet-style toolholding systems. At 5 inches overall length with a 1.25-inch flute length, it is sized for benchtop and floor-model drill presses as well as manual milling setups. Machinists and tool-and-die technicians are the primary users of this tool.

This chucking reamer is suited for reaming wire-gauge holes in the 0.2000 to 0.2499-inch decimal range, with a finished bore diameter of 0.2010 inches. It is used in job shop, production, and maintenance-repair-operations (MRO) environments where tight hole tolerances are required. Typical applications include precision bore finishing in mild steel, aluminum, brass, and similar machinable metals. The HSS construction performs well in moderate-speed, hand-fed operations using a drill press or lathe tailstock.

Key Features

• 0.2010-inch finished bore diameter falls in the 0.2000-0.2499-inch wire-gauge range
• High-speed steel construction provides durability in general machining conditions
• Six straight flutes with right-hand cut for smooth material removal and clean bore finish
• Bright, uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• Straight shank fits standard drill chucks and collet holders without adapters
• 5-inch overall length fits common drill press and lathe tailstock setups

Compatibility

Designed as an OEM-style replacement or direct-fit chucking reamer for standard straight-shank toolholding systems used in drill press, milling, and lathe tailstock applications requiring a 0.2010-inch finished bore diameter.

Installation Notes

Chucking reamers are installed and operated by machinists and skilled tradespeople following standard machining safety practices. Ensure the workpiece is securely fixtured and the spindle is powered down before inserting or removing the tool from the chuck. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not attempt to remove excessive stock with a reamer; pre-drill the hole close to final size before reaming.
