Hertel 30020400 Circuit Board Drill Bit No. 6 Wire

Product Description

The HERTEL 30020400 is a solid carbide circuit board drill bit designed for precision drilling in electronics manufacturing, PCB fabrication, and tight-tolerance metalworking applications. Built to wire gauge No. 6, this bit cuts at a diameter of 0.2040 inches (5.18 mm) with a 118-degree point angle for clean entry and minimal breakout. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation, reducing heat buildup during high-speed drilling operations. A bright polished finish minimizes friction at the cutting edge. Licensed technicians, machinists, and electronics fabricators working with precision drilling equipment rely on this bit for consistent, repeatable results.

This drill bit is suited for drilling cast iron, non-ferrous metals, and steel in both production-floor and bench-top settings. Its compact overall length of 1.5 inches makes it appropriate for use in CNC drilling machines, drill presses, and precision hand-held spindle units where clearance is limited. The tapered web configuration adds rigidity at the core, reducing deflection on entry. Heavy-duty grade construction supports continuous-use environments where bit longevity matters.

Key Features

• Solid carbide construction for hardness and wear resistance in metalworking applications
• No. 6 wire gauge diameter: 0.2040 inches (5.18 mm)
• 118-degree drill point angle for accurate self-starting entry
• Fast spiral flute with 35-degree helix angle for efficient chip clearing
• Tapered web for added core rigidity and reduced deflection
• Bright polished finish to reduce friction and extend cutting life
• Right-hand cutting direction; compatible with standard CNC and drill press spindles

Compatibility

Designed as an OEM-style replacement or direct-fit option for precision drilling setups requiring a No. 6 wire gauge solid carbide bit with a 5.18 mm shank diameter; confirm machine spindle clearance and collet size before installation.

Installation Notes

Installation and use should be performed by qualified machinists or electronics fabrication technicians familiar with CNC or precision drill press equipment. Secure the shank fully within the collet or chuck and verify runout before operation. Power down and de-energize all spindle drives before changing bits. Do not exceed the recommended spindle RPM rating for the bit diameter and material being drilled.
