Hertel 8272411 Chucking Reamer 0.511 in Hss 6 Flute

Product Description

The HERTEL 8272411 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth surface finish in through and blind holes. The 0.5110-inch cutting diameter, 2-inch flute length, and 8-inch overall length make it well suited for general-purpose reaming on drill presses, lathes, and CNC machining centers. Six straight flutes provide even chip evacuation and stable cutting action. The right-hand cutting direction is standard for conventional machine setups.

This chucking reamer is used in machine shop environments for finishing drilled or bored holes to close tolerances. It is appropriate for ferrous and non-ferrous materials in both production and maintenance machining. The straight-cylindrical shank seats directly in standard drill chucks, collet chucks, or floating reamer holders without additional adapters. Machinists, tool-and-die makers, and maintenance technicians performing precision bore work are the primary users of this tool.

Key Features

• 0.5110-inch reaming diameter for precise hole sizing within the 0.5000 to 0.6999-inch diameter range class
• 6 straight flutes for stable cutting and consistent chip removal
• HSS construction provides durability across a wide range of workpiece materials
• Bright, uncoated finish — no coating buildup to affect diameter accuracy
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits drill chucks and collet holders without modification

Compatibility

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

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or toolroom technician. Always bring the machine spindle to a full stop and lock out power before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a drill chuck or collet holder, verifying runout before cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
