Built to wire gauge size 20 with a decimal inch diameter of 0.1610 inches (4.09 mm), this bit features a 118-degree drill point angle and a 35-degree helix angle. The fast spiral geometry promotes aggressive chip evacuation, reducing heat buildup and improving hole quality in thin or layered materials. It is intended for use by machinists, electronics technicians, and trade professionals requiring tight-tolerance, repeatable drilling performance.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in cast iron, non-ferrous metals, plastics, and steel. Its solid carbide construction and heavy-duty grade make it appropriate for both production environments and precision repair work. The tapered web configuration provides added rigidity at the core, reducing deflection during drilling. With an overall length of 1.5 inches and a flute length of 0.75 inches, it fits compact spindle setups and benchtop drill presses commonly used in PCB and light fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in abrasive and hard materials\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for accurate starting and clean entry\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reduces core deflection during drilling\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 maintains sharp edge geometry without coating buildup in small-diameter holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-use drill bit for applications requiring wire gauge size 20 solid carbide tooling in circuit board, cast iron, non-ferrous metal, and plastic drilling operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or electronics fabrication technicians. Ensure the drill press or CNC spindle is fully powered down and locked out before inserting or removing the bit. Confirm collet or chuck size is compatible with the 4.09 mm (0.1610 inch) shank diameter before securing the tool. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as solid carbide tooling is rigid but can fracture under lateral load or improper setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1610 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 4.09 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\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Fast\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eShank Diameter\u003c\/strong\u003e: 0.1610 inches (4.09 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\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, Plastics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to +0.0000 inches\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: 30016100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51728872636722,"sku":"30016100","price":43.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7edb8b8d904181107cccd2cd0837a09_f8d747f3-445f-41d3-82ab-96755dc711a7.jpg?v=1788697217","url":"https:\/\/voomisupply.com\/products\/m-a-ford-30016100-circuit-board-drill-bit-size-20","provider":"Voomi Supply","version":"1.0","type":"link"}
