Sgs 07327 Circuit Board Drill Bit 1.15mm Solid Carbide

Product Description

The SGS 07327 is a solid carbide circuit board drill bit designed for precise, small-diameter drilling in printed circuit boards and similar high-precision applications. With a 1.15 mm (0.0453 inch) cutting diameter and a 130-degree four-facet point, it delivers clean entry and accurate hole placement with minimal walking. The uncoated solid carbide construction provides the rigidity and edge retention needed when drilling through abrasive or layered materials. At 38.10 mm (1.5 inches) overall length with a 1/8-inch (3.18 mm) shank, it fits standard PCB drilling spindles and compatible collet chucks used in production and repair environments.

This drill bit is suited for use in electronics manufacturing, PCB fabrication, and precision machining operations. The Series 105 designation and heavy-duty grade make it appropriate for both prototype and short-run production work. Its material application range includes aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium, making it a versatile choice for mixed-material circuit board assemblies and precision component drilling.

Key Features

• 1.15 mm (0.0453 inch) cutting diameter for fine-pitch PCB hole drilling
• 130-degree four-facet point for accurate entry and reduced thrust force
• Solid carbide construction — uncoated — for maximum rigidity and edge retention
• Regular spiral with 30-degree helix angle and tapered web for chip evacuation
• Right-hand cut, two-flute design compatible with standard PCB spindles
• 1/8-inch shank diameter fits common collet and chuck systems

Compatibility

Designed as an OEM-style replacement or production-use drill bit for standard PCB drilling equipment accepting a 1/8-inch shank. Compatible with aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium workpiece materials per manufacturer specifications.

Installation Notes

Installation and use should be performed by qualified machining or electronics manufacturing technicians familiar with high-speed drilling equipment. Ensure the spindle or collet chuck is fully powered down and secured before loading or removing the bit. Use appropriate RPM and feed rates for the target material and bit diameter — consult the machine manufacturer and tooling data for operating parameters. Inspect the cutting edge before each use; carbide bits are brittle and should be replaced if chipping or edge wear is observed.
