Hertel 30212500 Circuit Board Drill Bit 1/8 Inch

Product Description

The HERTEL 30212500 is a solid carbide circuit board drill bit designed for precision drilling in PCB fabrication and electronics assembly applications. The bit features a 1/8 inch (0.125 inch) diameter with a matching 1/8 inch straight shank, a 130-degree drill point angle, and a fast spiral flute geometry with a 35-degree helix angle. The tapered web configuration and bright polished finish support clean hole entry and efficient chip evacuation. At 1.5 inches overall length with a 3/8 inch flute length, this is a compact, purpose-built bit suited for controlled drilling in tight board layouts. Licensed electricians, electronics technicians, and PCB assembly professionals are the typical end users.

This drill bit is suited for drilling through a range of conductive and structural materials encountered in electronics and light fabrication work, including alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium. The fast spiral geometry aids in chip clearance when drilling thin-stack circuit board materials and metal substrates. It is sized for benchtop drill presses, CNC routing equipment, and precision hand drill setups commonly used in electronics manufacturing and field service environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• 130-degree drill point angle optimized for controlled entry and reduced walking
• Fast spiral flute with 35-degree helix angle for efficient chip evacuation
• Tapered web configuration supports stability through the cut
• Bright polished finish reduces friction and surface buildup during drilling
• Right-hand cutting direction compatible with standard drill press and CNC spindle setups

Compatibility

Designed as an OEM-style replacement and standard fitment drill bit for applications requiring a 1/8 inch solid carbide circuit board drill in fast spiral configuration. Compatible material applications include alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium as stated by the manufacturer.

Installation Notes

This bit is installed and operated by electronics technicians, PCB assembly professionals, or machinists using drill presses or CNC equipment rated for carbide tooling. Secure the shank firmly in a collet or chuck before operation and verify spindle speed is appropriate for the material and bit diameter. Solid carbide bits are brittle and should not be used in applications with significant lateral load or vibration without proper workholding. Inspect the bit for chipping or wear before each use and replace if the cutting edge shows visible damage.
