Hertel 30011000 Circuit Board Drill Bit No. 35 Solid Carbide

Product Description

The HERTEL 30011000 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related light manufacturing applications. Sized at No. 35 wire gauge (0.1100 inches, 2.79mm), it features a 118-degree drill point angle, a fast spiral flute design with a 35-degree helix angle, and a tapered web configuration. These characteristics promote efficient chip evacuation and accurate hole placement in thin, dense materials. At 1.5 inches overall length with a 0.625-inch flute length, this bit is built for compact, controlled cutting in automated or hand-held drilling setups. Licensed trades and precision manufacturing technicians reach for this bit when hole quality and dimensional accuracy are non-negotiable.

This drill bit is suited for use in circuit board drilling operations and precision machining environments where tight tolerances are required. The right-hand cutting direction and fast spiral geometry make it effective across a range of materials including cast iron, non-ferrous metals, and steel. The bright polished finish reduces friction and helps extend tool life during repetitive production drilling. It is sold individually and is appropriate for shops running small-batch or high-volume PCB and light metalwork operations.

Key Features

• No. 35 wire gauge size: 0.1100 inches (2.79mm) diameter for precision hole sizing
• 118-degree drill point angle for accurate starting and clean entry in circuit board and metal substrates
• Fast spiral flute with 35-degree helix angle promotes aggressive chip evacuation
• Solid carbide construction rated as heavy-duty grade for extended tool life
• Tapered web configuration improves rigidity and reduces walking at entry
• Bright polished finish minimizes friction and heat buildup during drilling

Compatibility

Designed for use in circuit board drilling applications and compatible with materials including cast iron, non-ferrous metals, and steel. Fits standard collet and chuck systems accepting a 0.1100-inch (2.79mm) shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trained technicians familiar with CNC or precision hand-drilling equipment. Ensure the spindle or drill press is powered down and secured before changing bits. Verify collet or chuck size matches the 2.79mm shank diameter before securing the bit. Follow equipment manufacturer guidelines for spindle speed and feed rate appropriate to the workpiece material.
