It carries a wire gauge size of 70, equal to 0.0280 inches (0.71 mm) in diameter, with a 1\/8-inch (0.1250 inch) shank and an overall length of 1.5 inches. The 130-degree four-facet point geometry delivers accurate, low-thrust entry with minimal wandering. A regular spiral with a 30-degree helix angle and tapered web configuration ensures efficient chip evacuation, making this bit suitable for production or repair drilling environments. Licensed electricians, electronics technicians, and precision fabricators are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in circuit board fabrication and rework applications requiring tight hole tolerances. The bright, uncoated solid carbide construction supports drilling into a broad range of workpiece materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced plastic, nickel, plastic, stainless steel, and titanium. The 0.4-inch flute length and right-hand cut make it compatible with standard CNC drilling machines and precision drill presses used in electronics manufacturing and light fabrication shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 70 diameter: 0.0280 inches (0.71 mm) for fine-pitch circuit board work\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree four-facet point for accurate entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eRegular spiral with 30-degree helix angle promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, tapered web configuration for clean, controlled drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8-inch shank collets and chucks on CNC circuit board drilling machines, precision benchtop drill presses, and compatible rotary tool setups.

Secure the workpiece firmly to prevent movement during the drilling cycle. Use appropriate spindle speeds for the workpiece material and bit diameter  -  consult the machine manufacturer or carbide tooling guidelines for recommended RPM ranges. Handle solid carbide tooling carefully to avoid chipping the cutting edges during storage and changeover.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 0.71 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: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches \/ 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\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\u003eDrill Bit Diameter 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\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 07303\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51741132194098,"sku":"07303","price":16.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e5ced0c49c0821acf760e3517028890.jpg?v=1788829524","url":"https:\/\/voomisupply.com\/products\/sgs-07303-circuit-board-drill-bit-size-70-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
