Hertel 30014950 Circuit Board Drill Bit No. 25 Solid Carbide

Product Description

The HERTEL 30014950 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related electronics manufacturing work. Sized to wire gauge No. 25 (0.1495 inches, 3.80 mm), it features a 118-degree drill point, a fast spiral with a 35-degree helix angle, and a tapered web configuration. The bright polished finish reduces chip adhesion and heat buildup during high-speed operation. Right-hand cutting direction is standard. This bit is intended for use by machinists, electronics technicians, and PCB fabrication professionals who require tight-tolerance, repeatable holes in thin, dense materials.

This drill bit is suited for drilling cast iron, non-ferrous metals, and steel in addition to its primary circuit board application. The fast spiral geometry promotes efficient chip evacuation in these materials. With a 0.75 inch flute length and a 1.5 inch overall length, the 30014950 fits standard CNC drilling spindles and manual drill presses used in precision fabrication and electronics assembly environments where small-diameter, accurate holes are required.

Key Features

• Wire gauge No. 25 sizing at 0.1495 inches (3.80 mm) for consistent, repeatable hole diameter
• Solid carbide construction for hardness and wear resistance in demanding materials
• 118-degree drill point angle for positive starting and clean entry
• Fast spiral with 35-degree helix angle promotes efficient chip evacuation
• Tapered web configuration adds strength at the cutting tip
• Bright polished finish reduces friction and heat at cutting edge

Compatibility

Designed as a standard wire-gauge circuit board drill bit for use in CNC drilling machines, precision drill presses, and compatible spindle tooling that accepts a 0.1495 inch (3.80 mm) shank diameter.

Installation Notes

Installation of small-diameter carbide drill bits should be performed by qualified machinists or electronics fabrication technicians. Ensure the spindle and collet are clean and free of debris before seating the shank to prevent runout. Carbide tooling is brittle and should not be used in setups with excessive vibration or lateral loading. Always confirm spindle speed and feed rate are appropriate for the workpiece material before beginning a drilling cycle.
