Sgs 07344 Circuit Board Drill Bit 1.65mm Solid Carbide

Product Description

The SGS 07344 is a solid carbide circuit board drill bit designed for precision drilling in printed circuit board fabrication and related small-diameter drilling applications. Built to Series 105 heavy-duty standards, it features a 130-degree four-facet point and a regular spiral with a 30-degree helix angle that promotes clean chip evacuation. The uncoated carbide construction delivers consistent performance across a wide range of workpiece materials. At 1.65 mm in diameter with a 1/8-inch shank, this bit is sized for use in standard PCB drilling spindles and small-format CNC drill presses. Typical installers include electronics manufacturing technicians, PCB prototyping shops, and precision machining professionals.

This drill bit is suited for drilling small-diameter holes in printed circuit boards, composite panels, and precision components. Its material compatibility spans aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium, making it a versatile option in electronics and light machining environments. The tapered web configuration helps maintain rigidity at small diameters, reducing deflection during high-speed drilling operations in both manual and CNC setups.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• 130-degree four-facet point for accurate positioning and reduced thrust force
• 30-degree helix angle with regular spiral for efficient chip removal
• Uncoated finish suitable for a broad range of materials including fiber-reinforced polymers and non-ferrous metals
• Tapered web configuration reduces deflection during precision drilling
• Right-hand cut, standard for CNC and manual PCB drill spindles

Compatibility

Compatible with workpiece materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. Fits standard 1/8-inch shank drill chucks and PCB CNC spindle collets.

Installation Notes

This bit is installed by electronics manufacturing technicians and precision machinists using CNC drill presses or manual drill stations equipped with 1/8-inch collets or chucks. Ensure the spindle is fully stopped and the machine is powered down before changing bits. Secure the bit firmly in the collet to the full shank engagement depth to prevent runout. Follow the machine manufacturer's recommended speeds and feeds for carbide tooling at this diameter.
