Hertel 59904466 Chucking Reamer 3/16 in Solid Carbide

Product Description

The HERTEL 59904466 is a solid carbide chucking reamer designed to produce precise, finished-diameter holes in metalworking applications. With a 3/16 inch (0.1875 inch) cutting diameter, 4-flute spiral geometry, and right-hand cut, this reamer delivers accurate bore sizing and a smooth surface finish in production and repair environments. The straight cylindrical shank seats securely in standard drill chucks, collets, or machine spindles. Solid carbide construction provides the rigidity and wear resistance needed when reaming hardened alloys, cast iron, and other abrasive materials. Machinists, toolroom operators, and CNC setup techs are the primary installers and users.

This reamer is suited for precision hole finishing on CNC machining centers, manual mills, drill presses, and lathes where tight tolerances are required. The spiral flute design aids chip evacuation during through-hole and shallow blind-hole operations. At 2-3/4 inches overall length with a 7/8 inch flute length, it is configured for short-reach applications typical in production shops, tool rooms, and maintenance machining. It ships individually and is appropriate for single-unit replacement or low-volume tooling setups.

Key Features

• Solid carbide construction for maximum rigidity and wear resistance in abrasive materials
• 0.1875 inch (3/16 inch) cutting diameter for precision hole finishing
• 4-flute spiral geometry promotes efficient chip evacuation
• Right-hand spiral direction and right-hand cutting for standard CNC and manual machine setups
• Straight cylindrical shank compatible with standard chucks and collet systems
• Compact 2-3/4 inch OAL suits short-reach and confined workpiece applications

Compatibility

Designed as a standard chucking reamer for use in CNC machining centers, knee mills, drill presses, and lathes equipped with drill chucks or collet holders accepting a straight cylindrical shank in the 3/16 inch diameter range.

Installation Notes

This reamer is installed and operated by machinists and toolroom professionals. Power down and lock out the machine spindle before loading or removing the tool from the chuck or collet. Ensure the shank is fully seated and the holding device is torqued to the machine manufacturer's specification before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
