It carries a wire gauge size of 53, equal to 0.0595 inches (1.51 mm) in diameter, and features a 130-degree four-facet point that reduces walking and produces clean entry holes with minimal burring. The 1\/8-inch shank measures 0.125 inches in diameter, and the overall length is 1.5 inches. The uncoated solid carbide construction delivers the rigidity and thermal resistance required when drilling hard substrates and composite laminates at high spindle speeds. Licensed machinists, electronics assembly technicians, and PCB fabrication shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling circuit board laminates, fiber-reinforced polymers, plastics, aluminum, copper alloys, cast iron, cobalt alloys, nickel, stainless steel, and titanium. The regular spiral geometry and 30-degree helix angle support efficient chip evacuation in both through-hole PCB work and precision machining of non-ferrous and exotic alloys. The tapered web configuration maintains core strength at small diameters. It is appropriate for both CNC drilling centers and manual precision drill presses where tight hole tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 53 (0.0595 inches \/ 1.51 mm) for precision small-diameter holes\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point reduces drill walk and improves hole entry quality\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction withstands high-speed drilling in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for non-ferrous metals, plastics, and fiber-reinforced polymers\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with regular spiral promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTapered web maintains core rigidity at 0.0595-inch drill diameter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute design compatible with standard CNC and manual spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC drilling centers and precision drill presses accepting a 1\/8-inch round shank.

Secure the 1\/8-inch shank firmly in a collet or drill chuck rated for the target spindle speed before operation. Carbide bits are brittle and can fracture if subjected to side-loading or excessive feed pressure, so use appropriate feeds and speeds for the workpiece material. Inspect the cutting edges under magnification before each use and replace the bit at the first sign of chipping or wear.\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: 53\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0595 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.51 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 (1\/8 inch \/ 3.18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.400 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\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: 07339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51739368653106,"sku":"07339","price":16.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1850ac965fcab1bccfcf9526700191ae.jpg?v=1788813688","url":"https:\/\/voomisupply.com\/products\/sgs-07339-circuit-board-drill-bit-size-53-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
