Hertel 30209600 No. 41 Circuit Board Drill Bit Solid Carbide

Product Description

The HERTEL 30209600 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and electronics manufacturing. Built to wire gauge size No. 41, it cuts a 0.0960-inch diameter hole with a 130-degree drill point angle optimized for clean entry and minimal breakout on thin, layered materials. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation, reducing heat buildup and bit deflection during high-speed operation. The bright polished finish lowers friction at the cutting edge. This bit is installed and used by electronics technicians, PCB fabricators, and precision machining professionals.

The 30209600 is suited for drilling small-diameter holes in circuit boards and similar precision workpieces. Its tapered web configuration and right-hand cutting direction make it compatible with standard CNC drilling spindles and benchtop drill presses used in electronics production environments. The 1/8-inch shank diameter fits common collets and chucks found in PCB drilling equipment. Beyond circuit board work, the material application range covers alloy steel, carbon steel, cast iron, high-temperature alloy, stainless steel, and titanium, making this bit a versatile option for small-diameter work in general precision machining.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed drilling
• No. 41 wire gauge size — 0.0960-inch cutting diameter for fine-tolerance holes
• 130-degree drill point angle reduces thrust force and minimizes material breakout
• Fast spiral, 35-degree helix angle promotes chip clearance and reduces heat
• Tapered web with right-hand cut for stable, accurate drilling
• Bright polished finish reduces friction and helps extend cutting edge life

Compatibility

Designed as a precision replacement or production-use circuit board drill bit for applications requiring a No. 41 wire gauge diameter hole; fits standard 1/8-inch collets and chucks on CNC PCB drilling machines and benchtop drill presses.

Installation Notes

This bit is installed by electronics technicians and precision machinists working with CNC drilling equipment or manual drill presses. Ensure the spindle and workpiece fixture are fully secured before beginning operation. Verify collet or chuck is clean and properly torqued to the 1/8-inch shank before use. Solid carbide bits are brittle — avoid side loading, impact, or use in applications requiring flexion.
