Hertel 79888814 Chucking Reamer 0.045in Solid Carbide

Product Description

The HERTEL 79888814 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. With a reamer diameter of 0.045 inches and a diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers accurate, repeatable results in production and job-shop environments. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited to ferrous and non-ferrous materials. At 1.5 inches overall length with a 0.375-inch flute length, this is a compact reamer built for shallow-hole finishing where clearance and precision matter. A licensed machinist or toolroom technician handles installation and setup.

This reamer is suited to CNC machining centers, manual lathes, and drill presses where a straight-shank, right-hand-cut tool can be held in a collet chuck or drill chuck. The four-flute straight flute geometry makes it appropriate for through-holes and short blind holes requiring a smooth, dimensionally accurate finish. Typical applications include precision bore finishing in mold and die work, medical component machining, and other industries where sub-0.05-inch hole diameters demand tight size control.

Key Features

• Solid carbide construction for rigidity and extended tool life in precision boring
• 0.045-inch reamer diameter with tolerance of 0.0000 to 0.0002 inches for tight-tolerance finishes
• Four-flute straight flute geometry for smooth cutting action in through and short blind holes
• Right-hand cutting direction with straight cylindrical shank for collet or chuck mounting
• Bright uncoated finish — ready for use without additional coating treatment

Compatibility

Designed as an OEM-style chucking reamer for use in standard collet chucks and drill chucks accepting straight-shank tooling in the applicable diameter range.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a precision collet or drill chuck before operation and verify runout with a dial indicator before cutting. Power down and lock out the machine spindle before changing or inspecting the reamer. Do not use this tool to remove large amounts of stock — reamers are finishing tools and require a properly sized pre-drilled or bored hole to function correctly.
