Hertel 30016100 Circuit Board Drill Bit No. 20 Solid Carbide

Product Description

The HERTEL 30016100 is a solid carbide circuit board drill bit designed for precise, clean drilling in printed circuit board fabrication and related precision machining applications. Built to wire gauge size No. 20, this bit measures 0.1610 inches (4.09 mm) in diameter with a matching shank diameter of 0.1610 inches. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation, reducing heat buildup and minimizing the risk of breakthrough burrs. A bright polished finish lowers friction and contributes to extended tool life in production drilling environments. Licensed HVAC, electrical, and precision manufacturing technicians working on control board assemblies or electronic subcomponents will find this bit suited to tight-tolerance work.

This bit is sized for No. 20 wire gauge applications and is well-suited for drilling through cast iron, non-ferrous metals, and steel in addition to circuit board substrates. With a 0.75-inch flute length and a compact 1.5-inch overall length, it fits standard high-speed drilling spindles and benchtop drill presses used in electronics manufacturing and repair shops. The tapered web configuration adds rigidity at the cutting tip, making it appropriate for both production runs and single-unit repair tasks where dimensional accuracy is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• No. 20 wire size, 0.1610 inches (4.09 mm) cutting diameter
• Fast spiral flute with 35-degree helix angle for efficient chip removal
• 118-degree drill point angle for clean entry on metallic and composite substrates
• Bright polished finish reduces friction and aids chip flow
• Tapered web configuration improves bit stability and cutting accuracy

Compatibility

Designed as an OEM-style replacement or production drill bit for applications requiring a No. 20 wire gauge solid carbide circuit board drill bit compatible with standard straight-shank drill chucks and high-speed spindles.

Installation Notes

Installation and use should be performed by qualified machinists or technicians familiar with precision drilling equipment. Secure the bit firmly in a compatible chuck rated for the shank diameter before operation. Always verify spindle speed settings are appropriate for the workpiece material and bit diameter before drilling. Inspect the cutting edge for chipping or wear before each use, as carbide tooling is brittle and should not be forced into hard material at excessive feed rates.
