Hertel 30002600 Circuit Board Drill Bit No. 71 0.66mm

Product Description

The HERTEL 30002600 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board (PCB) fabrication and electronics manufacturing. Sized at wire gauge No. 71, with a decimal inch diameter of 0.0260 inches (0.66 mm), this bit delivers the tight tolerances that PCB work demands. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation, reducing heat buildup during high-speed operation. The bright polished finish minimizes friction and helps maintain dimensional accuracy through extended use. This bit is installed and used by electronics technicians, PCB fabricators, and precision machining professionals.

This drill bit is suited for drilling small-diameter through-holes and vias in circuit board substrates as well as light-duty precision drilling in cast iron, non-ferrous metals, and steel. The tapered web configuration adds rigidity at the cutting edge, making it appropriate for applications where hole placement accuracy and clean entry are critical. With a 0.5-inch flute length and 1.5-inch overall length, it fits standard PCB drilling spindles and compatible CNC or manual drill press chucks accepting a 0.0260-inch shank.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• No. 71 wire gauge size, 0.0260 inches (0.66 mm) diameter
• Fast spiral flute with 35-degree helix angle for efficient chip removal
• 118-degree drill point angle for accurate starting and clean hole entry
• Tapered web configuration adds cutting-edge strength
• Bright polished coating reduces friction and aids chip flow
• Heavy-duty grade rated for cast iron, non-ferrous metals, and steel

Compatibility

Designed for use in PCB drilling applications and compatible with drill press spindles or CNC drilling equipment accepting a 0.0260-inch straight shank.

Installation Notes

This bit is installed by electronics technicians or precision machinists operating manual or CNC drill presses. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable tolerance for the application. Always match spindle speed to the material and bit diameter per the tooling manufacturer recommendations. Inspect the cutting edges before each use, as solid carbide bits can chip if subjected to lateral loading or improper feed rates.
