It carries a wire gauge size of 80, with a decimal diameter of 0.0135 inches (0.34 mm), and features a 130-degree four-facet point geometry that reduces walking and improves hole entry accuracy. The uncoated solid carbide construction delivers the rigidity and edge retention required for tight-tolerance work in hard and abrasive materials. At 1.5 inches overall length with a 0.125-inch shank diameter, this bit fits standard CNC drilling spindles and precision drill presses used in electronics manufacturing and prototype board work.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling small-diameter holes in PCBs, multi-layer boards, and similar thin-stock assemblies. Its regular spiral with a 30-degree helix angle and tapered web configuration promotes chip evacuation in shallow-hole drilling passes. The Series 105 designation places it within SGS tooling lines intended for high-precision, small-diameter applications. It is appropriate for use by machinists, electronics fabricators, and tool-and-die professionals working with non-ferrous metals, plastics, fiber-reinforced polymers, and similar substrates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 80 decimal diameter of 0.0135 inches for precision small-hole drilling\u003c\/li\u003e\n\u003cli\u003e130-degree four-facet point reduces bit walking and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and edge retention in abrasive materials\u003c\/li\u003e\n\u003cli\u003eRegular spiral with 30-degree helix angle promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds strength at the cutting tip\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a wide range of material types\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC drilling equipment and precision drill presses accepting a 0.125-inch shank.

Secure the 0.125-inch shank in a collet or chuck rated for the shank diameter before operation. Ensure the machine is fully stopped and locked out before changing bits. At this diameter, feed rate and spindle speed must be set conservatively to avoid bit deflection or breakage  -  consult the machine manufacturer and tooling speed-and-feed charts for solid carbide at size 80.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0135 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 0.34 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\u003c\/strong\u003e: 0.125 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.2800 inches (7.11 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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\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\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 07275\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743772246322,"sku":"07275","price":17.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5adc7b154af6bb776658c316e9c3e1ba.jpg?v=1788849609","url":"https:\/\/voomisupply.com\/products\/sgs-07275-circuit-board-drill-bit-size-80-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
