Ground to a wire gauge size 51 (0.0670 inches decimal), the bit features a 130-degree four-facet point geometry that promotes accurate entry, reduces walking, and minimizes burring on exit. The 1\/8-inch (0.1250 inch decimal) shank diameter fits standard CNC drill spindles and precision hand-piece chucks. With a regular spiral and 30-degree helix angle, this uncoated bit provides efficient chip evacuation in shallow-depth circuit board material. Installation and use are typically handled by electronics assembly technicians, CNC machine operators, and precision fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling through printed circuit boards, fiber-reinforced polymers, plastics, and non-ferrous metals encountered in electronics manufacturing environments. The two-flute configuration and tapered web keep cutting forces low, making it appropriate for thin, brittle substrates where heat and deflection must be controlled. It is also rated for use in aluminum, copper alloy, cast iron, cobalt alloy, nickel, stainless steel, and titanium workpieces, covering a broad range of materials found in precision machining and prototyping workflows.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 51 cutting diameter: 0.0670 inches (1.70 mm)\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point for accurate self-centering entry and reduced burring\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in abrasive substrates\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for non-ferrous metals, plastics, and fiber-reinforced polymers\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter compatible with standard precision drill chucks and CNC spindles\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with regular spiral and tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide circuit board drill bit for CNC drilling equipment and precision hand-piece tools that accept a 1\/8-inch shank.

Always ensure the workpiece is securely fixtured and the spindle is at a full stop before changing bits. Verify chuck runout is within tolerance before drilling fine-diameter holes, as excessive runout accelerates carbide breakage at this diameter. Follow equipment manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Inch)\u003c\/strong\u003e: 1\/8 inch (0.1250 inches decimal, 3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.4000 inches (10.16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (38.10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Iron, Cobalt Alloy, Copper Alloy, Fiber-Reinforced Polymers, Nickel, Plastics, Stainless Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 07346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743836209458,"sku":"07346","price":17.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15e0008e378b9b76d79ec2104574cdcc.jpg?v=1788850220","url":"https:\/\/voomisupply.com\/products\/sgs-07346-circuit-board-drill-bit-wire-51-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
