Hertel 79890141 Chucking Reamer 1/16 in Solid Carbide

Product Description

The HERTEL 79890141 is a solid carbide chucking reamer designed for precision hole finishing in machine tool applications. With a 1/16 inch (0.0625 inch) diameter and a tight tolerance of 0.0000 to 0.0002 inches, this reamer delivers accurate, finished-bore sizing in a single pass. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited for close-tolerance work in hard or abrasive materials. Machinists and tool-and-die professionals install this reamer in CNC machining centers, drill presses, and manual lathes where bore accuracy is critical.

This chucking reamer is suited for production and toolroom environments requiring precise hole finishing at small diameters. The straight cylindrical shank accepts standard collet chucks and drill chucks, making it compatible with a wide range of machine spindles. The 3/8 inch flute length accommodates shallow-depth reaming operations, while the four-flute straight geometry provides consistent chip evacuation and surface finish in through-holes and blind holes of appropriate depth.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive materials
• 0.0625 inch diameter with a tolerance of 0.0000 to 0.0002 inches for precise bore sizing
• Four straight flutes for consistent chip evacuation and smooth surface finish
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Straight cylindrical shank for compatibility with standard collet and drill chucks
• Right-hand cutting direction, standard for conventional machine reaming operations

Compatibility

Designed as an OEM-style chucking reamer for use in CNC machining centers, drill presses, and lathes equipped with collet or drill chucks accepting a straight cylindrical shank at the 1/16 inch diameter range.

Installation Notes

Installation is performed by qualified machinists following standard machine tool procedures. Ensure the machine spindle is fully stopped and the chuck is secure before installing or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality. Reaming is typically performed after drilling to final bore size; do not use this tool as a primary hole-making tool.
