Hertel 30015620 Circuit Board Drill Bit 5/32 in Solid Carbide

Product Description

The HERTEL 30015620 is a solid carbide circuit board drill bit designed for precise, small-diameter drilling in electronics and light industrial applications. It carries a 5/32 inch (0.1562 inch decimal) diameter with a 118-degree point angle and a fast spiral flute configuration. The bright, uncoated finish is standard for solid carbide tooling in this class. Overall length is 1.5 inches with a flute length of 0.75 inches. The tapered web construction supports rigidity at this diameter. This bit is installed by machinists, electronics fabricators, and skilled tradespeople working with circuit boards, thin metals, and similar substrates.

This drill bit is suited for drilling through cast iron, non-ferrous metals, and steel, as well as the composite and laminate materials common in circuit board fabrication. Its right-hand cut and 35-degree helix angle promote efficient chip evacuation in these materials. Typical applications include PCB hole drilling, precision metalwork, and light-duty machining operations where a rigid, small-diameter carbide bit is required. The 5/32 inch shank matches the cutting diameter, allowing direct collet or chuck mounting without a reduction sleeve.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard and abrasive materials
• 118-degree point angle suited for general-purpose drilling in metals and composites
• Fast spiral flute with 35-degree helix angle for efficient chip removal
• Tapered web design adds strength at small diameters
• Bright uncoated finish compatible with a wide range of cutting fluids
• Right-hand cut, standard rotation for use in conventional drill presses and CNC spindles

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide drill bit for circuit board and precision metalworking applications requiring a 5/32 inch diameter, 118-degree point, right-hand cut tool. Rated for cast iron, non-ferrous metal, and steel material applications.

Installation Notes

This bit is installed by machinists or electronics fabricators using a drill press, milling machine, or CNC machining center with an appropriately sized collet or drill chuck. Power down and de-energize the machine before securing or changing tooling. Use a cutting fluid appropriate for the workpiece material to extend tool life and maintain dimensional tolerance. Carbide tooling is brittle — avoid side loads and do not use in hammer or percussion drilling modes.
