Hertel 79889168 Chucking Reamer 0.09 in Solid Carbide

Product Description

The HERTEL 79889168 is a solid carbide chucking reamer designed for precise hole finishing in metalworking and machining operations. With a 0.09-inch diameter and a tight tolerance of 0.0000 to 0.0002 inches, this reamer delivers consistent, accurate bores in a single pass. The 4-flute straight configuration and bright uncoated finish make it well suited for a range of ferrous and non-ferrous materials. Machinists and tool-and-die professionals use this reamer for close-tolerance through-holes in production and job-shop environments. Overall length is 2 inches with a 0.5-inch flute length.

This chucking reamer is sized for small-diameter applications requiring high dimensional accuracy. The straight cylindrical shank allows direct mounting in standard drill chucks, collet chucks, and floating holders on CNC machining centers, manual lathes, and drill presses. Right-hand cutting direction is standard for conventional clockwise spindle rotation. Its compact 2-inch overall length keeps it rigid in short-reach setups, reducing deflection and improving hole finish on shallow or thin-section workpieces.

Key Features

• 0.09-inch diameter with 0.0000 to 0.0002-inch tolerance for tight, repeatable bore sizing
• 4-flute straight design for smooth chip evacuation and consistent surface finish
• Solid carbide construction for wear resistance and long tool life in hard or abrasive materials
• Bright uncoated finish suitable for a broad range of materials without coating buildup concerns
• Straight cylindrical shank for compatibility with standard chucks and collet systems
• Right-hand cut for use with standard clockwise spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders on CNC machining centers, lathes, and drill presses that accept a straight cylindrical shank.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists or tool-and-die technicians. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the tool from the chuck or collet. Use appropriate cutting fluid or coolant to extend tool life and maintain bore quality. Inspect the shank and flutes for chips or wear before each use to avoid dimensional drift or tool breakage.
