Built to Series 105 standards, this bit features a 2.8 mm (0.1102 inch) diameter and a 130-degree four-facet point that reduces walking and delivers accurate entry on hard, abrasive materials. The uncoated solid carbide construction provides the rigidity and wear resistance required for high-speed, small-diameter drilling. With a 1\/8-inch (3.18 mm) shank and a 1.5-inch overall length, it is suited for use in CNC drilling machines and precision drill presses. Electronics assembly technicians and fabrication shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for drilling circuit boards, laminates, and other non-ferrous or composite workpieces where dimensional accuracy and hole quality are critical. The heavy-duty grade carbide and tapered web configuration support demanding production drilling environments. It is also rated for use in alloy steels, titanium, and nonferrous materials per ISO workpiece material codes K, M, N, P, and S, making it a versatile option for mixed-material shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.8 mm (0.1102 inch) cutting diameter with a tight tolerance of -0.0003 to +0.0000 inch for precision hole sizing\u003c\/li\u003e\n\u003cli\u003e130-degree four-facet point reduces drill walk and chip load on entry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for maximum rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eUncoated finish — no risk of coating delamination affecting hole finish in sensitive PCB applications\u003c\/li\u003e\n\u003cli\u003eTapered web and 30-degree helix angle promote efficient chip evacuation in deep or stacked-board drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute design compatible with standard CNC spindle direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC PCB drilling machines and precision drill presses that accept a 1\/8-inch (3.18 mm) shank.

Ensure the spindle and work-holding fixture are secure and properly aligned before initiating a drill cycle. Use appropriate spindle speeds and feed rates for carbide tooling in the workpiece material — consult tooling charts for small-diameter carbide bits to avoid breakage. Do not use this bit in hand-held rotary tools where runout cannot be controlled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1102 inches\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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 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\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\u003eGrade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 07387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51738054951218,"sku":"07387","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77737fdd42fd8bcc7072b32d10116c41.jpg?v=1788795857","url":"https:\/\/voomisupply.com\/products\/sgs-07387-circuit-board-drill-bit-2-8-mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
