Hertel 2298107 Chucking Reamer 21.00mm Hss 8 Flute

Product Description

The HERTEL 2298107 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing at 21.00mm (0.8268 inches) diameter. The straight-cylindrical shank seats securely in standard chucks and collets. With 8 flutes and right-hand cutting direction, it produces clean, consistent bores in a single pass. Overall length is 9.5 inches with a 2.5-inch flute length. Licensed machinists and toolroom technicians use this reamer for final-pass finishing where tight dimensional tolerances are required.

This chucking reamer is suited for CNC machining centers, manual lathes, and drill presses in job shop, production, and maintenance environments. It is appropriate for reaming through-holes and blind holes in ferrous and non-ferrous materials where a finished bore at the 21.00mm nominal diameter is specified. The straight flute geometry makes it well-suited for shorter-chipping materials and general-purpose reaming at standard cutting speeds. It is sold individually and is not an over-size or under-size reamer, nor a dowel pin reamer.

Key Features

• 21.00mm (0.8268 inch) finished bore diameter
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• 8 straight flutes with right-hand cutting direction for clean, consistent bore finish
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Standard nominal diameter — not an over-size, under-size, or dowel pin reamer

Compatibility

Designed as a standard-tolerance chucking reamer for use in machine tool spindles accepting straight-cylindrical shanks, including CNC machining centers, turret lathes, and drill presses requiring a 21.00mm finished bore diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and chuck are clean and properly tightened before use. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Do not exceed the recommended cutting speed and feed rate for HSS tooling in the material being machined.
