Hertel 79890612 Chucking Reamer Wire Size 24 Solid Carbide

Product Description

The HERTEL 79890612 is a solid carbide chucking reamer designed to finish-ream precision holes to a wire size 24 diameter of 0.1520 inches. Built with four straight flutes and a straight cylindrical shank, this reamer is intended for use in CNC machining centers, drill presses, and manual lathes where tight bore tolerances are required. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited to finishing operations in ferrous and non-ferrous materials. Diameter tolerance is held to 0.0000 to 0.0002 inches over nominal, making it appropriate for applications demanding close fits and smooth bore finishes.

This chucking reamer is used in metalworking and machining environments where hole finishing to wire gauge sizes is required. Typical applications include fixture work, tooling plates, and precision component manufacture in job shop and production settings. The straight flute geometry suits through-hole and short blind-hole reaming in a variety of workpiece materials. Machinists and toolmakers working in manufacturing, maintenance, and repair operations are the primary users of this type of reamer.

Key Features

• Wire size 24 diameter: 0.1520 inches with a tolerance of 0.0000 to 0.0002 inches over nominal
• Solid carbide construction for rigidity and extended tool life in precision reaming
• Four straight flutes with right-hand cutting direction
• Bright, uncoated finish — no coating buildup affecting final hole size
• Straight cylindrical shank for standard chuck or collet holding
• Compact size: 2.5 inches overall length with a 0.75-inch flute length

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a chuck or collet capable of holding a straight cylindrical shank in the wire size 24 diameter range.

Installation Notes

Chucking reamers are installed and changed by qualified machinists following established shop safety procedures. Power down and lock out the machine spindle before changing tooling. Ensure the shank is fully seated and properly clamped in the chuck or collet before starting the cut. Use appropriate cutting fluid for the workpiece material to protect the tool edge and achieve the specified bore finish.
