Hertel 30001560 Circuit Board Drill Bit 1/64 Inch

Product Description

The HERTEL 30001560 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and electronics assembly work. It features a 118-degree drill point angle, a fast spiral flute configuration, and a tapered web for efficient chip evacuation. The bit measures 1/64 inch (0.40 mm) in diameter with a 1/4-inch flute length and a 1-1/2-inch overall length. The bright polished finish reduces friction and helps maintain dimensional accuracy in tight-tolerance applications. This is a heavy-duty grade bit suited for right-hand cutting in demanding production environments.

This bit is rated for use in cast iron, non-ferrous metals, and steel, making it versatile across circuit board and light metalworking drilling applications. It is typically used in CNC drilling machines, micro-drill presses, and PCB routing setups where consistent hole placement and minimal runout are critical. The 0.40 mm shank diameter is sized for standard PCB drill spindle collets. Technicians and machinists working in electronics manufacturing, prototyping shops, or precision fabrication will find this bit appropriate for high-cycle drilling at small diameters.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• 118-degree drill point angle for accurate hole initiation without walking
• Fast spiral flute design with 35-degree helix angle promotes rapid chip removal
• Tapered web configuration reduces thrust force during drilling
• Bright polished finish minimizes heat buildup and material adhesion
• Heavy-duty grade rated for cast iron, non-ferrous metals, and steel

Compatibility

Designed as an OEM-style replacement or production consumable for CNC PCB drilling equipment and micro-drill presses that accept a 0.40 mm diameter shank collet.

Installation Notes

Installation should be performed by a qualified machinist or electronics fabrication technician familiar with micro-drill tooling. Ensure the spindle and collet are clean and free of debris before seating the bit, as contamination at this diameter can cause runout and premature breakage. Power down and lock out the machine before changing tooling. Do not exceed the recommended RPM range for the drill diameter as specified by the machine manufacturer.
