Sgs 07323 Circuit Board Drill Bit Size 58 Solid Carbide

Product Description

The SGS 07323 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related electronic assembly work. Built to wire gauge size 58, the bit cuts a 0.0420-inch (1.07 mm) diameter hole with a 130-degree four-facet point that promotes accurate entry and reduces walking on hard, thin substrates. The 1/8-inch shank diameter measures 0.1250 inches and fits standard PCB drilling chucks. With a regular spiral and 30-degree helix angle, the flute geometry clears chips efficiently across a wide range of workpiece materials. This bit is intended for use by machinists, PCB fabricators, and precision drilling technicians.

This drill bit is suited for drilling printed circuit boards, fiber-reinforced polymers, plastics, aluminum, copper alloy, stainless steel, titanium, cobalt alloy, cast iron, and nickel-based materials. It fits residential, commercial, and industrial applications wherever tight-tolerance small-diameter holes are required. The uncoated solid carbide construction handles both abrasive composite laminates and metallic substrates without coating delamination. Series 105 is a standard PCB drill series used in high-speed spindle applications common to electronics manufacturing and precision shop environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in abrasive PCB materials
• Wire gauge size 58 cutting diameter of 0.0420 inches (1.07 mm)
• 130-degree four-facet point for accurate hole entry and reduced thrust force
• 1/8-inch (0.1250-inch) shank diameter compatible with standard PCB drill chucks
• 30-degree helix angle with regular spiral for effective chip evacuation
• Uncoated finish suitable for a broad range of metallic and non-metallic materials
• Tapered web configuration adds strength at the drill core

Compatibility

Designed as an OEM-style replacement and standard fit for Series 105 circuit board drilling applications requiring a wire gauge size 58 bit with a 1/8-inch shank. Compatible workpiece materials include aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium.

Installation Notes

This bit is installed by machinists and PCB fabrication technicians using high-speed CNC or manual drill spindles rated for small-diameter carbide tooling. Ensure the spindle and chuck are clean and free of runout before seating the 1/8-inch shank to avoid micro-fractures in the carbide. Carbide bits are brittle - do not use in applications with significant lateral load or hand-feed drilling without appropriate feed-rate control. Inspect the cutting tip under magnification before each use and replace at first sign of chipping.
