Hertel 74771015 Chucking Reamer 0.52 in Hss 6 Flute

Product Description

The HERTEL 74771015 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metalworking applications. With a 0.5200-inch reamer diameter, 8-inch overall length (OAL), and 2-inch straight flute length, this tool delivers consistent, accurate bore sizing when mounted in a drill press, lathe, or CNC machine. The bright, uncoated HSS construction handles a broad range of ferrous and non-ferrous materials. Six straight flutes and a right-hand cutting direction provide smooth material removal and reliable chip evacuation in through-hole and blind-hole finishing operations.

This chucking reamer is suited for machine shop environments, tool and die work, and production machining where tight hole tolerances are required. The straight-cylindrical shank seats securely in standard drill chucks or collets, making it a practical choice for machinists, toolmakers, and maintenance technicians working on precision components. It is not configured as a dowel pin reamer or an over/under size reamer, making it appropriate for standard nominal bore finishing.

Key Features

• 0.5200-inch reamer diameter for precision hole sizing
• 8-inch overall length with a 2-inch straight flute section
• 6-flute straight geometry for smooth cutting action and efficient chip clearance
• Right-hand cutting direction for standard machine operation
• HSS tool material with bright, uncoated finish — no coating to affect dimensional tolerance
• Straight-cylindrical shank for compatibility with standard drill chucks and collets

Compatibility

Designed as a machine chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers should be installed and operated by qualified machinists familiar with proper feeds, speeds, and cutting fluid selection for the workpiece material. Always secure the shank fully in the chuck or collet before operation and verify machine spindle runout is within acceptable limits to avoid bell-mouthing or premature tool wear. Inspect the reamer for edge condition before each use and replace if chipping or wear is observed. Follow applicable shop safety procedures and machine manufacturer guidelines during setup and operation.
