Hertel 30003700 Circuit Board Drill Bit No. 63 0.94mm

Product Description

The HERTEL 30003700 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and electronics manufacturing. Built to wire gauge No. 63, the bit measures 0.94 mm (0.0370 inches) in diameter with a matching 0.94 mm shank. The 118-degree drill point and fast spiral flute geometry promote clean entry and efficient chip evacuation in tight, precision-tolerance applications. The bright polished finish reduces friction and helps extend tool life in production environments. This is a heavy-duty grade bit suited for high-cycle-count operations handled by machining professionals and electronics fabrication technicians.

This drill bit is rated for use in cast iron, non-ferrous metals, and steel in addition to circuit board substrates, making it a versatile option for light-duty precision work beyond PCB drilling. The fast spiral design is particularly effective when chip removal speed matters in shallow, repetitive hole patterns. With a flute length of 0.625 inches (15.88 mm) and an overall length of 1.5 inches (38.10 mm), it fits standard CNC drill spindles and precision drill presses used in electronics and light machining shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• No. 63 wire gauge size — 0.94 mm diameter (0.0370 inches)
• 118-degree drill point angle for accurate, clean entry
• Fast spiral flute with 35-degree helix angle for efficient chip evacuation
• Tapered web configuration for added strength at the cutting tip
• Bright polished finish to reduce friction and heat buildup
• Heavy-duty grade rated for cast iron, non-ferrous metals, and steel

Compatibility

Designed as an OEM-style replacement or direct-use precision drill bit for CNC drill presses and spindle-driven machines requiring No. 63 wire gauge tooling with a 0.94 mm straight shank.

Installation Notes

Installation and tool changes should be performed by qualified machining or electronics fabrication technicians with the machine powered down and spindle fully stopped. Confirm shank diameter compatibility with the collet or chuck before seating the bit. Solid carbide bits are brittle — avoid side loading or flexing during setup. Follow machine manufacturer feed and speed guidelines for the material being drilled.
