Hertel 72033814 Chucking Reamer 0.3810in Hss 6 Flute

Product Description

The HERTEL 72033814 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing and smooth surface finishes in drilled or bored holes. It measures 0.3810 inches in diameter with an overall length of 7 inches and a flute length of 1.75 inches. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. With 6 flutes and right-hand cutting direction, it provides stable, chatter-resistant performance during reaming operations. Weighing 0.19 pounds, it is a lightweight and easy-to-handle tool for shop and field use.

This chucking reamer is suited for machine shop, toolroom, and production environments where hole tolerances demand a finished, reamed bore. It is intended for use in lathes, drill presses, milling machines, and CNC machining centers with appropriate workholding. The 0.3810-inch diameter falls within the 0.3500 to 0.3999 inch reamer diameter range, making it a standard size for common bore finishing tasks in ferrous and non-ferrous materials. Licensed machinists, toolroom technicians, and industrial maintenance professionals are the primary users of this tool.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the reamer from the chuck or collet. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Always confirm the reamer is properly seated and secured before initiating the cut.
