Hertel 72296759 Chucking Reamer 0.4980 in Hss 6 Flute

Product Description

The HERTEL 72296759 is a 6-flute chucking reamer designed for precision hole finishing in metal cutting applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores to a 0.4980-inch diameter. It features a straight-cylindrical shank for secure chuck mounting and a right-hand spiral flute geometry that promotes clean chip evacuation and consistent surface finish. With a 6-inch overall length and 2-inch flute length, it is sized for general-purpose reaming on drill presses, lathes, and CNC machining centers. Machinists and tool-and-die professionals use this reamer where tight hole tolerances are required.

This chucking reamer is suited for production and maintenance machining environments where repeatable bore dimensions are critical. Its dowel pin reamer classification makes it appropriate for finish-reaming holes that must accept close-tolerance pins or fitted fasteners. The right-hand cutting direction and spiral flutes work together to reduce chatter and improve hole roundness in ferrous and non-ferrous materials. It weighs approximately 0.15 pounds, making it easy to handle during setup and tool changes.

Key Features

• 0.4980-inch reaming diameter for precision bore finishing
• 6-flute right-hand spiral geometry for reduced chatter and clean chip flow
• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Bright, uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Classified as a dowel pin reamer for close-tolerance pin-fit applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.4980-inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations and cutting tool safety. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before mounting or removing the reamer. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never exceed the recommended feed rates for HSS tooling in the material being machined.
