It features a 5\/64 inch (0.0781 inch) diameter with a 1\/8 inch shank and a 130-degree four-facet point that centers cleanly and reduces walking on entry. The uncoated solid carbide construction delivers the rigidity and edge retention needed when drilling through fiber-reinforced polymers, plastics, and non-ferrous metals. Overall length is 1-1\/2 inches with a 3\/8 inch flute length. Right-hand cut with a regular spiral and a 30-degree helix angle. Installed by machinists, electronics fabricators, and precision trades.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling printed circuit boards, composite laminates, and thin non-ferrous workpieces in both production and repair environments. The four-facet point geometry minimizes delamination and breakout on entry and exit, which is critical when working with fiber-reinforced polymer boards and delicate substrates. Compatible material types include aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium. The tapered web configuration supports chip evacuation in deep or blind holes at this diameter range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/64 inch (0.0781 inch) cutting diameter with tight tolerance of -0.0003 to +0.0000 inch\u003c\/li\u003e\n\u003cli\u003e130-degree four-facet point for accurate entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter fits standard precision chucks and collets\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with regular spiral and tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for aluminum, plastics, fiber-reinforced polymers, stainless steel, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling circuit boards, composite laminates, and thin-section workpieces in materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium.

Secure the workpiece firmly to prevent movement at entry and exit. Use appropriate spindle speeds for the workpiece material and this diameter range  -  excessive feed rate at small diameters can cause bit breakage. Inspect the cutting edge before each use; solid carbide bits are brittle and should be handled carefully to avoid chipping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/64 inch (0.0781 inch \/ 1.98 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: 1\/8 inch (0.1250 inch \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3\/8 inch (0.4000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (38.10 mm)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inch\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: 0.05 pounds\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: 07355\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743938117938,"sku":"07355","price":15.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef41cd046c8cb7872008f8fe255922ac.jpg?v=1788851603","url":"https:\/\/voomisupply.com\/products\/sgs-07355-circuit-board-drill-bit-5-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
