Hertel 30014700 Circuit Board Drill Bit Size 26 0.1470 in

Product Description

The HERTEL 30014700 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit board fabrication and light manufacturing applications. Sized at wire gauge 26 with a decimal diameter of 0.1470 inches (3.73 mm), this bit features a 118-degree drill point angle and a fast spiral flute configuration with a 35-degree helix angle. The bright polished finish reduces friction and chip buildup during cutting. Licensed tradespeople and precision machining technicians rely on this type of bit where consistent hole geometry and tight tolerances are required in small-diameter drilling operations.

This drill bit is suited for drilling cast iron, non-ferrous metals, and steel in precision machining environments. The fast spiral design promotes aggressive chip evacuation, making it appropriate for circuit board and thin-material drilling scenarios where clean, accurate holes are critical. The tapered web configuration adds rigidity while maintaining the slender shank profile needed for close-tolerance work. Typical use cases include PCB shops, light fabrication, and prototype assembly environments where wire gauge 26 drill sizing is specified.

Key Features

• Wire gauge 26 diameter: 0.1470 inches (3.73 mm) with a tight tolerance of -0.0005 to +0.0000 inches
• 118-degree drill point angle for effective penetration in ferrous and non-ferrous materials
• Fast spiral flute with 35-degree helix angle for efficient chip evacuation
• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• Bright polished coating reduces cutting friction and extends tool life
• Tapered web configuration provides added bit stability at small diameters

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for applications specifying wire gauge 26 sizing in circuit board drilling, light machining, and precision fabrication operations involving cast iron, non-ferrous metals, and steel.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or precision drilling technicians familiar with small-diameter carbide tooling. Before mounting, ensure the drill press or CNC spindle is fully powered down and the collet or chuck is clean and free of debris. Solid carbide bits are brittle compared to high-speed steel and should not be subjected to lateral loading or impacts during setup. Follow machine manufacturer guidelines for feed rate and spindle speed when drilling at this diameter.
