Hertel 2290385 Chucking Reamer 19/32 in Hss Straight Flute

Product Description

The HERTEL 2290385 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, it delivers consistent bore sizing in ferrous and non-ferrous materials. The reamer measures 19/32 inch (0.5938 inch decimal) in diameter with an 8 inch overall length and a 2 inch flute length. The straight-cylindrical shank seats securely in standard drill chucks and machine tool holders. Right-hand cutting direction follows conventional reaming practice. This tool is sized for the 0.5000 to 0.6999 inch diameter range and is appropriate for machine shop technicians, toolroom operators, and precision maintenance machinists.

The HERTEL 2290385 suits production and toolroom reaming operations where tight hole tolerances and smooth bore finishes are required. It is a standard chucking-style reamer intended for use in drill presses, lathes, machining centers, and similar machine tools running controlled feed and speed cycles. The bright finish makes it well suited for general-purpose reaming in steel, cast iron, aluminum, and similar workpiece materials. It is sold as a single unit and is appropriate for shops that need a reliable, ready-to-use HSS reamer without specialized coatings.

Key Features

• 19/32 inch (0.5938 inch) reamer diameter for precise hole finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Straight flute geometry for smooth, consistent cutting action
• Bright, uncoated finish suitable for general-purpose reaming applications
• Straight-cylindrical shank for positive chuck retention in standard machine tool holders
• Right-hand cutting direction, standard for conventional reaming setups

Compatibility

Designed as an OEM-style chucking reamer compatible with standard drill chucks and machine tool holders accepting a straight-cylindrical shank in the 0.5000 to 0.6999 inch diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in the drill chuck or collet before use, and ensure the machine spindle is fully stopped before tool changes. Follow established speeds and feeds for HSS reamers appropriate to the workpiece material, and apply cutting fluid as recommended to extend tool life and improve bore finish. Do not use a reamer to remove excessive stock — pre-drill or bore the hole to near-final size before reaming.
