Sgs 07363 Circuit Board Drill Bit Size 44 Solid Carbide

Product Description

The SGS 07363 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit boards and other tight-tolerance applications. Built to wire gauge size 44 with a decimal diameter of 0.0860 inches, this bit features a 130-degree four-facet point that reduces walking and improves entry accuracy on hard substrates. The 1/8-inch shank diameter is compatible with standard PCB drilling spindles and precision drill chucks. With a regular spiral, 30-degree helix angle, and tapered web configuration, it produces clean, consistent holes in a wide range of materials. It is installed and used by electronics assembly technicians, precision machinists, and skilled fabricators.

This drill bit is suited for drilling aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. It performs in both light-duty benchtop drill press setups and CNC PCB drilling equipment. Its uncoated solid carbide construction is well-matched for applications where coating buildup or contamination is a concern, particularly in composite and polymer materials. The compact 1.5-inch overall length fits confined fixturing arrangements common in circuit board production environments.

Key Features

• Wire gauge size 44 (0.0860 inches / 2.18 mm) decimal diameter for precision PCB hole sizing
• 130-degree four-facet point angle reduces drill walk and improves hole entry accuracy
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• Uncoated finish eliminates coating-related contamination risk in composite and polymer drilling
• 1/8-inch (0.1250-inch decimal) shank diameter fits standard precision drill chucks and PCB spindles
• Regular spiral with 30-degree helix angle and tapered web for efficient chip evacuation
• Right-hand cut, two-flute design suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for precision drilling operations requiring a wire gauge size 44 solid carbide 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 per Series 105 material application ratings.

Installation Notes

Installation and use should be performed by qualified machinists or electronics fabrication technicians familiar with precision drilling equipment. Ensure the drill chuck or collet is properly tightened to the 1/8-inch shank before operation, and confirm spindle speed is appropriate for the workpiece material and bit diameter. Solid carbide bits are brittle - avoid side loading, lateral pressure, or using them in flex-shaft tools not rated for rigid carbide tooling. Inspect the bit for chipping or tip damage before each use.
