Hertel 72034556 Chucking Reamer 0.455 in Hss 6 Flute

Product Description

The HERTEL 72034556 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate, smooth bore sizing in drilling and machining operations. It features a 0.4550-inch cutting diameter, a 7-inch overall length, and a 1-3/4-inch flute length with 6 straight flutes for consistent material removal. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. Right-hand cutting direction is standard for conventional CNC and manual machine tool setups. This tool is installed and used by machinists and tool-and-die professionals.

This chucking reamer is suited for reaming through-holes and blind holes in steel, cast iron, aluminum, and similar machinable materials. It fits standard machine tool setups including drill presses, lathes, and machining centers where a floating or rigid reamer holder is used. The 0.4550-inch diameter places it in the 0.4000 to 0.4999-inch diameter range, making it appropriate for finish-reaming holes that require tight dimensional tolerances in production and job-shop environments.

Key Features

• 0.4550-inch cutting diameter for precision bore finishing
• 6 straight flutes provide consistent chip evacuation and surface finish
• HSS construction offers toughness across a broad range of workpiece materials
• Bright, uncoated finish suitable for general-purpose reaming applications
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders on drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank tool.

Installation Notes

A licensed machinist or qualified tool operator should install and use this reamer. Power down and lock out the machine spindle before mounting or removing the tool. Secure the straight-cylindrical shank fully within the chuck or collet to the recommended grip depth before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
