Hertel 30006350 Circuit Board Drill Bit Size 52 Solid Carbide

Product Description

The HERTEL 30006350 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related small-diameter drilling applications. Built to wire gauge size 52, the bit measures 0.0635 inches (1.61 mm) in diameter with a 118-degree point angle and a fast spiral flute configuration. The bright polished finish reduces friction and aids chip evacuation. Overall length is 1.5 inches with a flute length of 0.625 inches. Right-hand cut geometry and a 35-degree helix angle make this bit well-suited for clean-entry holes in hard and non-ferrous materials. It is typically installed by machinists, electronics fabricators, and precision drilling technicians.

This drill bit is intended for use in materials including cast iron, non-ferrous metals, and steel. Its small diameter and solid carbide construction make it a practical choice for PCB drilling, precision instrument manufacturing, and any application requiring accurate small-hole drilling. The tapered web configuration provides added rigidity at this diameter, reducing deflection during entry. Sold individually, it fits standard collet-style drill chucks and CNC drilling equipment that accept shank diameters of 0.0635 inches.

Key Features

• Wire gauge size 52 diameter: 0.0635 inches (1.61 mm)
• 118-degree point angle for accurate hole entry
• Solid carbide construction for hardness and wear resistance
• Fast spiral flute with 35-degree helix angle for efficient chip removal
• Bright polished finish reduces friction and heat buildup
• Right-hand cut with tapered web for rigidity at small diameters

Compatibility

Designed as an OEM-style precision drill bit for use in collet-style and CNC drilling equipment that accepts a 0.0635-inch shank diameter. Suitable for drilling cast iron, non-ferrous metals, and steel.

Installation Notes

Installation and use of this bit is typically performed by machinists or electronics fabricators operating drill presses, CNC drilling machines, or precision hand-held equipment. Ensure the workpiece and machine spindle are fully secured before operation. At this diameter, excessive feed pressure will cause bit breakage — follow machine manufacturer feed rate and speed recommendations for solid carbide tooling. Proper collet or chuck condition is critical when running small-diameter carbide bits.
