Sgs 07307 Circuit Board Drill Bit 1/32 in Solid Carbide

Product Description

The SGS 07307 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and fine-detail machining applications. It measures 0.0313 inches (1/32 inch) in diameter with a 1/8-inch shank diameter and an overall length of 1.5 inches. The 130-degree four-facet point geometry promotes accurate hole entry and reduces walking on hard, thin, or laminated substrates. The uncoated solid carbide construction provides rigidity and heat resistance at small diameters where high-speed steel bits would deflect or break. Two flutes with a 30-degree helix angle and a tapered web configuration support chip evacuation in deep, narrow bores. This bit is suited for use in CNC drilling machines, PCB drill presses, and precision benchtop equipment operated by electronics technicians, machinists, and trade professionals working with fine-pitch materials.

The SGS 07307 is appropriate for drilling alloy steels, aluminum, cast iron, copper alloys, cobalt alloys, nickel, stainless steel, titanium, plastics, and fiber-reinforced polymers. Its primary workpiece material codes are K, M, N, P, and S, covering a broad range of metallic and non-metallic substrates. Typical applications include PCB through-hole drilling, precision fixture work, and small-diameter hole generation in composite or hard materials where dimensional accuracy is critical. The right-hand cut direction is standard for conventional CNC and manual drilling setups.

Key Features

• Solid carbide construction for rigidity and long tool life at small diameters
• 130-degree four-facet point angle reduces drill walking and improves hole-entry accuracy
• 1/32-inch (0.0313-inch) cutting diameter with a tolerance of -0.0003 to +0.0000 inches
• 1/8-inch shank diameter fits standard PCB drill chucks and collet holders
• Regular spiral with 30-degree helix angle and tapered web for efficient chip evacuation
• Uncoated finish compatible with a wide range of workpiece materials including fiber-reinforced polymers and titanium

Compatibility

Designed as an OEM-style replacement and standard-use drill bit for CNC circuit board drilling machines and precision drill presses that accept a 1/8-inch shank. Compatible with aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium workpieces as indicated by material application codes K, M, N, P, and S.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or electronics fabrication technicians familiar with CNC drilling equipment. Ensure the spindle and work-holding fixture are powered down and fully stopped before inserting or removing the bit from the chuck or collet. Verify shank seating depth and runout before beginning a production run, as deflection at small diameters can cause premature breakage. Always operate within the spindle speed and feed rate parameters recommended for solid carbide tooling in the specific workpiece material.
