Hertel 30016600 Circuit Board Drill Bit Size 19 Solid Carbide

Product Description

The HERTEL 30016600 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and light metalworking applications. It carries a wire gauge size of 19, which corresponds to a decimal diameter of 0.1660 inches (4.22 mm), and features a 118-degree point angle suited for accurate entry on flat workpiece surfaces. The bright, uncoated finish preserves the carbide substrate for maximum hardness and wear resistance. With an overall length of 1.5 inches and a fast spiral flute design, this bit moves chips efficiently and maintains hole geometry in demanding materials.

This bit is intended for use in CNC drilling equipment, drill presses, and precision hand-held power tools where tight hole tolerances are required. It is well suited for drilling cast iron, non-ferrous metals, and steel, making it appropriate for electronics manufacturing environments as well as general metalworking shops. The tapered web and 35-degree helix angle contribute to stable cutting performance across these material groups. Trade machinists, electronics fabricators, and precision job shops are the primary installers and users of this bit.

Key Features

• Solid carbide construction for high hardness and extended tool life in abrasive materials
• Wire gauge size 19 with a 0.1660-inch (4.22 mm) cutting diameter
• 118-degree point angle for accurate, self-centering entry on flat stock
• Fast spiral flute with 35-degree helix angle for efficient chip evacuation
• Tapered web configuration improves rigidity and reduces deflection
• Bright uncoated finish compatible with a wide range of cutting fluids and dry cutting setups

Compatibility

Designed as a standard wire-gauge circuit board drill bit suitable for use in CNC PCB drilling machines and precision drill presses that accept a 0.1660-inch shank diameter.

Installation Notes

Installation should be performed by qualified machinists or electronics fabrication technicians familiar with CNC tooling and precision drill setups. Secure the shank fully in the collet or chuck before operation and confirm runout with a dial indicator where tolerances are critical. Use appropriate cutting fluid or coolant for the material being drilled. Inspect the cutting edges before each use, as solid carbide is brittle and susceptible to chipping if dropped or improperly stored.
