Hertel 72034853 Chucking Reamer 0.4850 in Hss 6 Flute

Product Description

The HERTEL 72034853 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, it delivers accurate sizing on through and blind holes where tight tolerances are required. The reamer measures 0.4850 inches in diameter with an overall length of 8 inches and a 2-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. At 0.19 pounds, it is lightweight enough for extended use in vertical mills, drill presses, and manual or CNC drilling setups. Licensed machinists and toolroom technicians are the primary users of this tool.

This chucking reamer is suited for production and job-shop environments where finish-bore quality and dimensional accuracy matter. It is commonly used to bring drilled holes to final size in ferrous and non-ferrous metals. The 0.4850-inch diameter falls within the 0.4000 to 0.4999 inch reamer diameter range, making it a standard choice for bore finishing in that size class. Right-hand cutting direction and 6 straight flutes produce a clean, consistent finish with minimal chatter. It is packaged individually and sold as a single unit.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists or toolroom technicians familiar with machine tool operation. Ensure the machine spindle is fully stopped and the tool is securely chucked before beginning any operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the reamer for wear or edge damage before each use and do not force the tool through an undersized or misaligned bore.
