Hertel 30019600 Circuit Board Drill Bit Size 9 Solid Carbide

Product Description

The HERTEL 30019600 is a solid carbide circuit board drill bit sized to wire gauge 9, equivalent to 0.1960 inches (4.98 mm) in diameter. It features a 118-degree point angle and a fast spiral flute geometry with a 35-degree helix angle, designed to produce clean, accurate holes in circuit board substrates and precision metalwork. The bright polished finish reduces friction and aids chip evacuation. With an overall length of 1.5 inches and a 0.75-inch flute length, this bit is built for short-reach, high-precision drilling applications where tight dimensional tolerances are required. The diameter tolerance is held to -0.0005 to +0.0000 inches.

This bit is suited for use in machine shops, electronics manufacturing, and precision fabrication environments. It is appropriate for drilling cast iron, non-ferrous metals, and steel. The tapered web configuration and fast spiral promote efficient chip removal in both CNC and manual drill press setups. Technicians and machinists working on PCB fabrication, light metalwork, or tight-tolerance drilling operations will find this bit appropriate for production and repair use alike.

Key Features

• Wire gauge size 9, 0.1960 inches (4.98 mm) diameter with shank diameter matched to bit diameter
• 118-degree point angle for general-purpose entry and centering performance
• Fast spiral with 35-degree helix angle for efficient chip evacuation
• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Bright polished finish to reduce friction and improve hole surface finish
• Diameter tolerance of -0.0005 to +0.0000 inches for precision fitment requirements

Compatibility

Designed as an OEM-style replacement or production-use drill bit for CNC drilling machines, drill presses, and manual drilling setups requiring a wire gauge size 9 solid carbide bit rated for cast iron, non-ferrous metals, and steel applications.

Installation Notes

Installation and use should be performed by a qualified machinist or trained technician familiar with carbide tooling. Secure the bit firmly in the chuck or collet before operation and verify runout before beginning a drilling cycle. Solid carbide bits are brittle compared to high-speed steel and should not be subjected to side loading or flexing. Always follow machine manufacturer feed and speed recommendations for carbide tooling in the specific material being drilled.
