Hertel 2298156 Chucking Reamer 21.50mm Hss 8 Flute

Product Description

The HERTEL 2298156 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it produces accurate, smooth bores to a diameter of 21.50 mm (0.8465 inches). The straight-cylindrical shank seats securely in standard chucks, and the 8-flute geometry distributes cutting load evenly for consistent surface finish and dimensional accuracy. With an overall length of 10 inches and a flute length of 2-5/8 inches, it handles typical through-hole and blind-hole reaming tasks on the mill or drill press. Right-hand cutting direction follows standard convention for most CNC and manual machine setups.

This reamer is suited for production and maintenance machining environments where final bore sizing to 21.50 mm is required. It is appropriate for use on ferrous metals, aluminum, and similar workpiece materials where HSS tooling is a common and cost-effective choice. Machinists, tool-and-die makers, and general job-shop operators will find it a practical fit for reaming pre-drilled holes to close tolerance.

Key Features

• 21.50 mm (0.8465 inch) finished bore diameter
• High-speed steel (HSS) construction for durability across a range of metal workpieces
• 8-flute straight design for balanced cutting action and improved surface finish
• Bright/uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank for direct chuck mounting without adapters
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, milling machines, and CNC machining centers equipped with a compatible chuck accepting a straight-cylindrical shank at the 21.50 mm diameter range.

Installation Notes

Installation and use should be performed by qualified machinists. Power down and lock out the machine spindle before loading or removing the reamer from the chuck. Ensure the shank is fully seated and the chuck is tightened to the machine specification before operation. Always apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
