Hertel 2412047 Chucking Reamer 1/16 in Cobalt Steel

Product Description

The HERTEL 2412047 is a chucking reamer designed for precision hole finishing in metalworking and machining applications. Built from cobalt steel with a bright, uncoated finish, this reamer delivers the hardness and heat resistance required for reaming ferrous and hard alloy workpieces. It features a 4-flute, right-hand spiral configuration that promotes smooth cutting action and efficient chip evacuation. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With a reamer diameter of 0.0625 inches and an overall length of 2.5 inches, it is suited for close-tolerance finish reaming of small-diameter bores. Machinists and tool room technicians are the primary users.

This reamer is used in light-duty precision machining setups where accurate bore sizing and surface finish are required. The 0.5-inch flute length is appropriate for shallow through-holes and blind holes at this diameter range. It is a standard production and maintenance item for machine shops, tool rooms, and manufacturing facilities working with small-diameter bores in the 0.0500 to 0.0999 inch decimal range. The right-hand cutting direction is compatible with conventional spindle rotation on mills, drill presses, and lathes.

Key Features

• Cobalt steel construction for improved hardness and heat resistance over standard high-speed steel
• 4-flute, right-hand spiral design for smooth cutting and efficient chip removal
• Straight-cylindrical shank for compatibility with standard chucks and collet holders
• Bright, uncoated finish suitable for general-purpose reaming applications
• Right-hand cutting direction matches conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with chucks or collet holders accepting straight-cylindrical shanks in the small-diameter reamer range.

Installation Notes

Installation is performed by qualified machinists familiar with precision hole finishing operations. Secure the shank firmly in the chuck or collet before use and verify runout before engaging the workpiece. Always reduce spindle speed relative to drilling operations and apply appropriate cutting fluid to extend tool life and maintain bore finish quality. Inspect the reamer for wear or chipping before each use.
