Hertel 79889150 Chucking Reamer 0.088 in Solid Carbide

Product Description

The HERTEL 79889150 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.088 inches and a tight diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent, accurate hole sizing in a single pass. The straight flute geometry and right-hand cutting direction make it well suited for through-hole reaming in a range of materials. At 2 inches overall length with a 0.5-inch flute length, it is compact enough for close-tolerance work in production and job shop environments. Machinists and tool-and-die professionals are the primary users of this type of tooling.

This chucking reamer is intended for use in CNC machining centers, drill presses, and manual lathes where precise hole finishing is required after drilling. The straight cylindrical shank allows it to be held securely in standard drill chucks or collet holders. It is suited for reaming small-diameter holes in steel, aluminum, brass, and similar materials where dimensional accuracy and surface finish are critical. The bright, uncoated finish makes it appropriate for dry cutting or use with cutting fluids where coating adhesion is not required.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter reaming
• 0.088 inch diameter with 0.0000 to 0.0002 inch tolerance for precision hole sizing
• 4-flute straight flute design for consistent chip evacuation and finish quality
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight cylindrical shank for secure chuck or collet clamping
• Bright, uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet holders on CNC machining centers, drill presses, and manual lathes requiring 0.088 inch hole finishing capability.

Installation Notes

This reamer should be installed by a qualified machinist in a properly sized chuck or collet to minimize runout before use. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Pre-drill the hole to the appropriate undersize before reaming to avoid overloading the flutes. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
