Hertel 79888970 Chucking Reamer 1/16 in Solid Carbide

Product Description

The HERTEL 79888970 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 1/16 inch (0.0625 inch) diameter and a four-flute straight configuration, it delivers tight diameter tolerances of 0.0000 to 0.0002 inches, making it well suited for applications where bore accuracy is critical. The bright, uncoated finish is standard for solid carbide reamers used in general-purpose finishing operations. A straight cylindrical shank allows secure clamping in standard drill chucks, collets, or machine tool holders. Right-hand cutting direction is conventional for most CNC and manual machining setups.

This reamer is intended for use in machine shop environments where precise hole sizing is required in materials such as steel, aluminum, brass, and other machinable metals. The small 1/16 inch diameter makes it appropriate for fine-tolerance work in watch components, instrument parts, aerospace detail parts, or any application requiring a finished bore at this diameter. It is typically run on CNC machining centers, knee mills, or drill presses with appropriate speed and feed control. Installation and operation are performed by machinists and tool-and-die professionals.

Key Features

• Solid carbide construction provides rigidity and wear resistance for precise, repeatable hole finishing
• Four straight flutes produce a smooth bore surface in through-hole and shallow blind-hole applications
• Diameter tolerance of 0.0000 to 0.0002 inches ensures tight, consistent sizing
• Straight cylindrical shank for compatibility with standard chucks and collets
• Bright, uncoated finish suitable for general-purpose machining operations
• Right-hand cutting direction matches standard spindle rotation on most machine tools

Compatibility

Designed as an OEM-style precision cutting tool for use in standard straight-shank tool holders, drill chucks, and collets sized to accept a 1/16 inch cylindrical shank in CNC and manual machining equipment.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Power down and lock out the machine spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the chuck or collet is torqued to the machine manufacturer's specification before running. Use appropriate cutting fluid and verify spindle speed and feed rate are within the recommended range for solid carbide reamers at this diameter to avoid tool breakage or bore oversizing.
