Ford 30016950 Circuit Board Drill Bit Size 18","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD 30016950 is a solid carbide, fast spiral circuit board drill bit designed for precision drilling in printed circuit board and light industrial applications. Built to Series 300 specifications, this bit carries a wire gauge size of 18, translating to a decimal diameter of 0.1695 inches (4.31 mm). The 118-degree drill point angle and tapered web configuration promote clean entry and efficient chip evacuation. With a 35-degree helix angle and right-hand cutting direction, it is suited for consistent, repeatable hole quality in production and repair environments. Licensed electricians, PCB technicians, and precision machine operators are the typical end users.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use on cast iron, non-ferrous metals, plastics, and steel workpieces. The fast spiral flute geometry helps clear chips quickly during high-speed drilling operations, reducing heat buildup and extending tool life. A flute length of 0.75 inches (19.05 mm) and an overall length of 1.5 inches (38.10 mm) keep the bit rigid for close-tolerance work in tight board layouts or small-part fixtures. The heavy-duty grade designation reflects its construction for repeated use in demanding shop and field conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003eWire size 18 (0.1695 inches \/ 4.31 mm) diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle with tapered web for accurate starting and reduced walking\u003c\/li\u003e\n\u003cli\u003eFast spiral, 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, compatible with standard drill press and CNC spindle setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use across cast iron, non-ferrous metals, plastics, and steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production-use solid carbide circuit board drill bit for applications involving cast iron, non-ferrous metals, plastics, and steel workpieces requiring a wire gauge size 18 hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and removal should be performed with the machine powered down and the spindle fully stopped. Secure the bit firmly in a compatible collet or chuck rated for the 4.31 mm shank diameter before operation. Follow applicable shop safety procedures and machine manufacturer guidelines for speed and feed settings appropriate to the workpiece material. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can fracture if run at incorrect parameters or if the bit contacts a workpiece while spinning up.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 4.31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1695 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 4.31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (19.05 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: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metals, Plastics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 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: 300\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30016950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51728332718386,"sku":"30016950","price":46.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7edb8b8d904181107cccd2cd0837a09_022aa4cc-7138-4d76-b306-748971f43ce8.jpg?v=1788690504","url":"https:\/\/voomisupply.com\/products\/m-a-ford-30016950-circuit-board-drill-bit-size-18","provider":"Voomi Supply","version":"1.0","type":"link"}
