Built to wire gauge size No. 38 (0.1015 inches decimal, 2.58 mm), it features a 130-degree four-facet point that reduces walking and improves hole entry accuracy. The uncoated solid carbide construction delivers hardness and wear resistance well beyond high-speed steel. With a 1\/8-inch (0.1250-inch decimal) shank diameter and 1-1\/2 inches overall length, this bit is sized for use in precision drilling machines, CNC drill presses, and handheld rotary tools. It is installed and operated by electronics technicians, PCB fabricators, and skilled trade professionals requiring repeatable, burr-minimized hole quality.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling through fiber-reinforced polymers, plastics, aluminum, copper alloy, cast iron, stainless steel, nickel, cobalt alloy, and titanium. The regular spiral geometry and 30-degree helix angle support efficient chip evacuation in both through-hole and blind-hole drilling scenarios. The tapered web configuration adds strength at the core while keeping the cutting geometry sharp. Typical applications include PCB hole drilling, small-diameter production drilling, and precision prototype work where hole diameter tolerance is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear life compared to HSS\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point reduces drill walking and improves entry accuracy\u003c\/li\u003e\n  \u003cli\u003eWire gauge No. 38 size  -  0.1015 inches (2.58 mm) cutting diameter\u003c\/li\u003e\n  \u003cli\u003eUncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with regular spiral for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eTight diameter tolerance of -0.0003 to +0.0000 inches for precision fitment\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute design  -  Series 105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with precision drill presses, CNC drilling machines, and rotary tools accepting a 1\/8-inch shank.

Ensure the chuck is clean and the bit is seated securely before operation to prevent runout. Match spindle speed to the workpiece material per standard carbide drilling guidelines  -  carbide bits require higher RPM and lower feed force than HSS equivalents. Avoid side loading or flexing the bit during drilling, as solid carbide is brittle and will fracture under lateral stress.\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: No. 38\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.58 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: 1-1\/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 inches\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\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: 07378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51741011706162,"sku":"07378","price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/beaf97ccccddfbf12145a6b3dbbf81ec.jpg?v=1788828867","url":"https:\/\/voomisupply.com\/products\/sgs-07378-circuit-board-drill-bit-no-38-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
