Hertel 30022100 Circuit Board Drill Bit No. 2 Wire

Product Description

The HERTEL 30022100 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and similar high-accuracy applications. It measures 0.2210 inches (5.61 mm) in diameter, matching a No. 2 wire gauge size, with a 118-degree drill point angle and a fast spiral flute geometry. The 35-degree helix angle promotes efficient chip evacuation, and the tapered web configuration adds stability at the cutting tip. Finished with a bright polished coating, this bit is built for clean, consistent entry and exit holes in demanding production or repair environments. A licensed technician or machinist familiar with PCB tooling is the typical installer.

This drill bit is suited for use in cast iron, non-ferrous metals, and plastics, making it applicable across a range of light machining and electronics manufacturing tasks. The fast spiral design helps clear chips quickly in gummy or layered materials such as FR4 laminate, aluminum, and copper-clad board stock. With an overall length of 1.5 inches and a flute length of 0.75 inches, the bit fits standard PCB drilling spindles and benchtop drill presses used in both production and repair settings.

Key Features

• Solid carbide construction for wear resistance and dimensional stability in repetitive drilling
• No. 2 wire gauge size at 0.2210 inches (5.61 mm) diameter with tight tolerance of -0.0005 to +0.0000 inches
• 118-degree drill point angle for general-purpose entry into metals and plastics
• Fast spiral with 35-degree helix angle for aggressive chip evacuation
• Tapered web configuration improves tip rigidity and reduces walking
• Bright polished finish reduces friction and facilitates chip flow

Compatibility

Designed as an OEM-style replacement or production consumable for standard PCB drilling operations and benchtop drill presses accepting a 0.2210-inch shank diameter.

Installation Notes

This bit should be installed and operated by machinists or technicians familiar with PCB or precision drilling equipment. Secure the shank firmly in the chuck and verify runout before beginning a drilling cycle. Power down and lock out the spindle before changing bits. Do not exceed the recommended feed and speed ratings for the workpiece material, and inspect the cutting edge for wear or chipping between production runs.
