Hertel 30200800 Circuit Board Drill Bit 0.2mm Carbide

Product Description

The HERTEL 30200800 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and electronics manufacturing. Built from solid carbide, this bit delivers the rigidity and edge retention needed to drill clean, accurate holes in PCB laminates, fiberglass, and similar hard, abrasive substrates. The drill measures 0.2mm (0.0079 inches) in diameter with a 130-degree drill point angle optimized for controlled entry into hard materials. The bright polished finish reduces friction and heat buildup at the cutting edge. This bit is handled by machinists and PCB production technicians operating CNC drill presses and high-speed spindle equipment.

This drill bit is suited for high-precision PCB drilling applications where small-diameter hole accuracy is critical. The regular spiral flute geometry and tapered web configuration support chip evacuation in shallow-depth circuit board work. The 0.125-inch (1/8 inch) shank diameter is a standard size compatible with common PCB drilling machine collets and CNC spindle chucks. It is used in electronics manufacturing environments, prototype board shops, and precision machining operations where tight hole tolerances are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive PCB laminates
• 130-degree drill point angle for controlled entry and accurate hole placement
• 0.2mm drill diameter with a tolerance of -0.0003 to +0.0000 inches for tight hole sizing
• Bright polished coating reduces friction and extends cutting edge life
• Regular spiral flute with tapered web for efficient chip evacuation in shallow cuts
• Right-hand cutting direction compatible with standard CNC and manual drill spindles

Compatibility

Designed for use in CNC PCB drilling machines and high-speed drill presses equipped with a 1/8-inch collet or compatible spindle chuck accepting a 0.125-inch shank diameter.

Installation Notes

Installation and operation should be performed by qualified machinists or PCB fabrication technicians familiar with high-speed small-diameter carbide tooling. Power down and lock out the spindle before loading or removing the bit. Solid carbide bits are brittle and will fracture if dropped or subjected to side loading — handle with care and avoid using this bit for materials or feed rates outside its design parameters. Verify collet runout before drilling to maintain hole diameter tolerance.
