Hertel 72035140 Chucking Reamer 0.5140 in Hss 6 Flute

Product Description

The HERTEL 72035140 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, this reamer delivers consistent diameter control at 0.5140 inches. The straight-cylindrical shank seats securely in standard chucks, and the right-hand cutting direction suits conventional drilling setups. With an overall length of 8 inches and a 2-inch flute length, it handles typical through-hole and blind-hole reaming tasks on manual lathes, drill presses, and CNC turning centers. Machinists and tool-and-die professionals are the primary installers.

This reamer is suited for moderate stock removal and finishing passes in ferrous and non-ferrous materials where tight hole tolerances are required. The 6-flute, straight-flute geometry produces a smooth surface finish with minimal chatter in stable fixturing setups. It is a practical choice for job shops, maintenance facilities, and production machining environments working in the 0.5000 to 0.6999-inch diameter range. The bright finish makes it well-suited for use with cutting oils and soluble coolants without buildup concerns common to coated tools.

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers accepting a straight-cylindrical shank in the 0.5000 to 0.6999-inch reamer diameter range.

Installation Notes

Chucking reamers are installed and operated by machinists and tool-and-die technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation, and verify runout with a dial indicator when close-tolerance work is required. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Inspect the reamer for edge wear or chipping before each use and remove it from service if cutting edges are damaged.
