Hertel 72293574 Chucking Reamer 0.3745 in Hss 6 Flute

Product Description

The HERTEL 72293574 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 delivers accurate sizing in a wide range of ferrous and non-ferrous materials. The reamer measures 0.3745 inches in diameter with an overall length of 5 inches and a flute length of 1.75 inches. Six straight flutes and a right-hand cutting direction provide clean, consistent stock removal. The straight-cylindrical shank allows direct mounting in standard drill chucks, collets, and floating holders used in CNC and manual machine tool setups.

This chucking reamer is suited for production and maintenance machining environments where reamed hole tolerance and surface finish are critical. It is used in drilling and boring operations on lathes, drill presses, and machining centers. The 0.3745-inch diameter falls within the 0.3500 to 0.3999-inch range, making it appropriate for finishing holes that require tight dimensional control. Machinists, tool-and-die makers, and maintenance technicians working in industrial and manufacturing settings are the typical end users.

Installation Notes

Installation and use should be performed by qualified machinists familiar with machine tool operation and cutting tool safety. Ensure the machine spindle is fully stopped and the tool is securely seated in the chuck or collet before beginning the operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended feed rate or depth of cut for HSS tooling in the given material.
