Hertel 79888913 Chucking Reamer 0.0555 in Solid Carbide

Product Description

The HERTEL 79888913 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.0555 inches and a tight tolerance of 0.0000 to 0.0002 inches, it produces accurate, close-tolerance bores in a single pass. The 4-flute straight flute geometry provides smooth, consistent cutting action. The bright, uncoated carbide construction handles a wide range of workpiece materials. Overall length is 1.5 inches with a 0.375-inch flute length, making it well suited for shallow, precision bore applications on CNC machines, drill presses, and manual milling setups.

This chucking reamer is intended for machine-tool use in production and job-shop environments where consistent hole quality and tight dimensional tolerances are required. It fits standard chuck holders and collet systems compatible with straight cylindrical shanks. Machinists, tool-and-die makers, and precision machining professionals use this reamer to finish pre-drilled holes to exact diameter in metals and other rigid materials. Its compact overall length and small diameter make it appropriate for intricate workpieces requiring fine bore sizing.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision boring
• Diameter tolerance of 0.0000 to 0.0002 inches for close-fit hole finishing
• 4 straight flutes for smooth, chatter-resistant cutting action
• Bright, uncoated finish suitable for a broad range of materials
• Straight cylindrical shank for secure seating in standard chuck and collet holders
• Right-hand cutting direction for conventional machine-tool spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard machine-tool chuck and collet holders accepting straight cylindrical shanks in the applicable diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with machine-tool operation and cutting tool safety practices. Power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the holding device is properly torqued before beginning the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
