Sgs 07379 Circuit Board Drill Bit 2.6 Mm Solid Carbide

Product Description

The SGS 07379 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit boards and a broad range of industrial materials. Measuring 2.6 mm (0.1024 inches) in diameter with a 1/8-inch shank (3.18 mm), this bit features a 130-degree four-facet point that promotes accurate entry and minimizes drill wander. The overall length is 1.5 inches (38.10 mm), with a flute length of 0.4 inches (10.16 mm). A 30-degree helix angle and regular spiral geometry support efficient chip evacuation. The uncoated solid carbide construction provides the hardness and dimensional stability required for tight-tolerance work.

This bit is suited for production and repair environments where clean, accurate small-diameter holes are required. The Series 105 heavy-duty grade makes it appropriate for drilling aluminum, cast iron, copper alloys, stainless steel, titanium, cobalt alloys, nickel, fiber-reinforced polymers, and plastics. Typical users include electronics manufacturers, PCB technicians, and precision machine shops. The right-hand cutting direction and tapered web configuration are standard for CNC and hand-held high-speed drilling applications in these materials.

Key Features

• 2.6 mm (0.1024 inches) diameter with tight tolerance of -0.0003 to +0.0000 inches for precise hole sizing
• 130-degree four-facet point minimizes drill wander and improves entry accuracy
• Solid carbide construction provides hardness and wear resistance across a wide material range
• 30-degree helix angle with regular spiral for consistent chip evacuation
• 1/8-inch (3.18 mm) shank diameter compatible with standard collets and chucks
• Uncoated finish suitable for use across metals, polymers, and fiber-reinforced materials

Compatibility

Designed as an OEM-style precision drill bit for use in CNC drilling machines, PCB drill presses, and high-speed hand-held drilling equipment accepting a 1/8-inch shank.

Installation Notes

Installation and use should be performed by qualified machinists or electronics technicians familiar with small-diameter carbide tooling. Secure the shank fully in the collet or chuck before operation to prevent runout. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper feed rate control, or dropping the bit. Ensure spindle speeds are appropriate for the workpiece material and bit diameter before beginning the operation.
