Hertel 72034911 Chucking Reamer 0.4910 in Hss 6 Flute

Product Description

The HERTEL 72034911 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 accurate sizing and smooth surface finishes in through-holes and blind holes. The reamer measures 0.4910 inches in diameter with an 8-inch overall length and a 2-inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks and collet holders. Right-hand cutting direction suits conventional machine operation. At 0.19 pounds, the tool is lightweight and well-suited to bench drill presses, turret lathes, and CNC machining centers where consistent bore quality is required.

This chucking reamer is used in general-purpose machine shop environments, tool rooms, and production floors where hole tolerances demand more precision than a drill alone can provide. It is appropriate for finishing pre-drilled or bored holes in steel, cast iron, aluminum, and similar machinable materials. The 0.4910-inch diameter falls within the 0.4000 to 0.4999-inch decimal inch range and is sized for close-tolerance fit work. Machinists, tool-and-die makers, and maintenance technicians are the primary installers and operators of this tool.

Key Features

• 0.4910-inch finished diameter for precise hole sizing within the 0.4000 to 0.4999-inch range
• 6 straight flutes for smooth cutting action and consistent chip evacuation
• HSS construction provides toughness and wear resistance across a wide range of machinable materials
• Bright uncoated finish maintains sharp cutting edges without coating buildup concerns
• Straight-cylindrical shank for direct chuck or collet mounting with minimal runout
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, turret lathes, and CNC machining centers equipped with a compatible straight-shank chuck or collet system sized for a 0.4910-inch diameter reamer body.

Installation Notes

This tool is operated by qualified machinists following standard machine shop safety procedures. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet before operation and verify runout before beginning a cut. Power down and de-energize the machine spindle completely before installing or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
