Ground to a wire size 71 diameter of 0.026 inches (0.66 mm), this bit features a 130-degree four-facet point that reduces walking and improves entry accuracy on hard, abrasive, and layered materials. The uncoated solid carbide construction delivers rigidity and wear resistance well beyond high-speed steel alternatives. With a 1.5-inch overall length and a 0.125-inch (1\/8 inch) straight shank, the bit fits standard drill chucks and CNC spindles used in circuit board fabrication and precision machining setups. Cutting direction is right-hand with a regular spiral and a 30-degree helix angle. Intended for use by machinists, electronics fabricators, and skilled trade professionals working with close-tolerance materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling through a wide range of materials including aluminum, cast iron, copper alloy, cobalt alloy, nickel, stainless steel, titanium, plastics, and fiber-reinforced polymers. The four-facet point geometry and tapered web configuration make it particularly effective in fiber-reinforced polymer circuit board substrates where conventional drill geometry tends to delaminate or tear. Applications include PCB through-hole drilling, precision fixture drilling, and prototype fabrication where hole location accuracy and clean entry are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 71 diameter: 0.026 inches (0.66 mm) with a tight tolerance of -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e130-degree four-facet point for accurate entry and reduced drill walk\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life on abrasive materials\u003c\/li\u003e\n\u003cli\u003e0.125-inch (1\/8 inch) shank diameter compatible with standard CNC and manual drill chucks\u003c\/li\u003e\n\u003cli\u003eRegular spiral with 30-degree helix angle and tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use across metals, plastics, and fiber-reinforced polymers\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, 2-flute design, Series 105\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8-inch collet or chuck systems on CNC drilling machines, drill presses, and PCB drilling equipment where wire-gauge diameter bits are specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or electronics fabrication technicians familiar with small-diameter carbide tooling. Solid carbide bits are brittle and require rigid setups with minimal runout to avoid breakage  -  confirm spindle and chuck runout is within tolerance before use. Always power down and secure the machine before changing bits. Feed rate and spindle speed should be set according to the workpiece material; consult machining data references for recommended surface footage for carbide tooling in the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 71\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0260 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.66 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: 0.1250 inches (1\/8 inch \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3400 inches (8.64 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\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: 07301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51739856961842,"sku":"07301","price":16.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/518adce80e5494f12f164e5d106ad3cc.jpg?v=1788819728","url":"https:\/\/voomisupply.com\/products\/sgs-07301-circuit-board-drill-bit-71-wire-0-026-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
