Sgs 07343 Circuit Board Drill Bit Size 52 Solid Carbide

Product Description

The SGS 07343 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit board fabrication and related small-hole applications. It carries a wire gauge size of 52 with a decimal diameter of 0.0635 inches and is ground to a 130-degree four-facet point for clean entry and minimal thrust. The uncoated carbide construction delivers consistent cutting performance across a wide range of workpiece materials. With an overall length of 1.5 inches and a 1/8-inch shank diameter, this bit is sized for use in standard CNC drilling spindles and precision drill presses. A 30-degree helix angle and regular spiral geometry support efficient chip evacuation in shallow-hole operations.

This bit is suited for drilling printed circuit boards, electronic assemblies, and precision components in light manufacturing, prototyping, and electronics fabrication environments. The four-facet point geometry and tapered web configuration make it a practical choice when hole position accuracy and exit-side quality are critical. Qualified machinists, electronics manufacturing technicians, and PCB fabrication specialists are the primary installers. It handles a broad material range including aluminum, copper alloy, stainless steel, plastics, fiber-reinforced polymers, titanium, nickel, cobalt alloy, and cast iron.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• 130-degree four-facet point geometry for precise entry and reduced thrust force
• Wire gauge size 52 (0.0635 inches / 1.61 mm) for tight-tolerance hole sizing
• 30-degree helix angle with regular spiral for effective chip evacuation
• Tapered web configuration supports point strength at reduced diameters
• Uncoated finish compatible with a broad range of workpiece materials including plastics, metals, and composites

Compatibility

Designed for use in CNC PCB drilling machines, precision drill presses, and spindle units accepting 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

Installation is performed by qualified machinists or electronics fabrication technicians. Secure the 1/8-inch shank firmly in the collet or chuck before operation and verify runout before drilling to protect the small-diameter bit from deflection. Always power down and de-energize any automated drilling equipment before changing tooling. Follow equipment manufacturer guidelines for spindle speed and feed rate when working with carbide tooling at this diameter.
