Hertel 72020001 Chucking Reamer 0.2000 in Hss 6 Flute

Product Description

The HERTEL 72020001 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing at 0.2000 inches diameter with a 5-inch overall length and a 1.25-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks and machine tool holders. Right-hand cutting direction suits conventional CNC machining centers, manual lathes, and drill presses. With six flutes, this reamer produces smooth, consistent bore finishes in a single pass on through-holes and blind holes within its diameter range.

This reamer is suited for precision reaming operations in job shops, production machining environments, and tool rooms. It handles a range of ferrous and non-ferrous materials at the 0.2000-inch diameter. The compact flute length makes it practical for moderate-depth holes where rigidity and finish quality are priorities. Machinists and tool room professionals select this size for close-tolerance work where drilled holes require finishing to a precise fit.

Key Features

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, manual lathes, and drill presses equipped with a drill chuck or collet holder sized for a straight-cylindrical shank at the 0.2000 inch diameter class.

Installation Notes

Installation is performed by machinists and tool room professionals. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet before operation to prevent runout. Always verify spindle speed and feed rate recommendations for HSS tooling and the specific workpiece material before use. Inspect the reamer for edge chipping or wear before each use and do not force a worn or damaged tool.
