Hertel 30015200 Circuit Board Drill Bit No 24 Solid Carbide

Product Description

The HERTEL 30015200 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit boards and similar tight-tolerance applications. Built to wire gauge size No. 24, this bit measures 0.1520 inches (3.86 mm) in diameter with a matching 3.86 mm shank diameter, a 118-degree drill point angle, and a fast spiral flute configuration with a 35-degree helix angle. The bright polished finish reduces friction during cutting. A tapered web configuration improves chip evacuation and cutting stability. This bit is intended for use by machinists, electronics assemblers, and trade professionals requiring accurate, repeatable small-diameter drilling.

This drill bit is rated for heavy-duty use and suited for drilling cast iron, non-ferrous metals, and steel in addition to circuit board substrates. The fast spiral geometry makes it effective where quick chip removal is critical, such as in production drilling environments or repair work where multiple holes must be drilled cleanly without regrinding. The 0.75 inch flute length and 1.5 inch overall length keep it compact for use in tight fixtures or drill presses handling small workpieces.

Key Features

• Solid carbide construction for durability and rigidity in small-diameter drilling
• No. 24 wire size, 0.1520 inches (3.86 mm) diameter with tight tolerance of -0.0005 to +0.0000 inches
• 118-degree drill point angle for general-purpose and circuit board applications
• Fast spiral flute with 35-degree helix angle for efficient chip evacuation
• Tapered web configuration improves cutting stability and reduces thrust
• Bright polished finish minimizes friction and built-up edge

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide circuit board drill bit compatible with standard drill chucks and collet holders accepting a 3.86 mm (0.1520 inch) shank diameter. Rated for use in cast iron, non-ferrous metals, and steel applications.

Installation Notes

This bit is installed by machinists or electronics technicians using drill presses, CNC drilling machines, or hand-held precision drilling equipment. Ensure the collet or chuck is rated for the 3.86 mm shank before seating the bit. Always power down and de-energize drilling equipment before changing bits. Carbide tooling is brittle — avoid lateral loading or drop impacts that can cause chipping or fracture.
