Hertel 72034762 Chucking Reamer 0.476 in Hss Straight Flute

Product Description

The HERTEL 72034762 is a straight-flute chucking reamer designed for precision hole finishing in machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate diameter sizing at 0.4760 inches across a 2-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collets. At 8 inches overall length, it provides adequate reach for typical workpiece depths encountered in production and job-shop environments. Right-hand cutting direction is standard. This tool is installed and operated by machinists, tool-and-die makers, and maintenance technicians working with drill presses, lathes, or CNC machining centers.

This chucking reamer is suited for reaming pre-drilled holes to a finished diameter of 0.4760 inches in ferrous and non-ferrous materials. The 6-flute straight configuration provides consistent surface finish and controlled material removal in through-holes and blind holes alike. Typical applications include bore finishing in mechanical assemblies, fixture plates, and component manufacturing where tight dimensional tolerances are required.

Key Features

• 0.4760 inch finished bore diameter with straight-cylindrical shank for secure chuck mounting
• 6 straight flutes for smooth, consistent material removal and surface finish
• HSS construction provides toughness and wear resistance across a range of workpiece materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• Right-hand cutting direction, compatible with standard machine spindle rotation
• 8 inch overall length for adequate reach in common workpiece setups

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with drill chucks or collet systems accepting a straight-cylindrical shank at approximately 0.4760 inches diameter.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with reaming procedures. Always bring the machine spindle to a complete stop before loading or unloading the reamer from the chuck or collet. Ensure the pre-drilled pilot hole is sized appropriately — typically 0.005 to 0.015 inches undersize — before reaming; do not attempt to ream directly from a raw casting or without a pilot hole. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
