Hertel 9851007 Chucking Reamer 0.8780 in Hss 8 Flute

Product Description

The HERTEL 9851007 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 consistent sizing and surface finish in drilled or bored holes. The reamer measures 0.8780 inches in diameter with a 10-inch overall length and a 2-5/8-inch flute length. Eight straight flutes provide smooth cutting action with right-hand rotation. The straight-cylindrical shank seats securely in standard drill chucks, collet chucks, or machine spindles. Machinists and tool-and-die professionals use this reamer for finish-reaming operations on lathes, drill presses, and machining centers.

This chucking reamer is suited for precision finish reaming in general metalworking, tool rooms, and production machining environments. It handles a range of ferrous and non-ferrous materials where tight hole tolerances and smooth bore finishes are required. The 0.8780-inch diameter places it in the 0.7000 to 0.9999 inch reamer diameter range, making it appropriate for medium-to-large bore finish work. It is sold individually and ships as a single unit per package.

Installation Notes

This reamer is installed by a machinist or tool-and-die professional in a lathe, drill press, or machining center spindle. Ensure the machine is fully powered down and the spindle is stopped before changing tooling. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent runout. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
