It carries a No. 68 wire gauge size, translating to a decimal diameter of 0.0310 inches (0.79 mm). The 130-degree drill point and fast spiral flute geometry promote clean entry and efficient chip evacuation in tight, shallow-depth bores. The tapered web configuration adds rigidity at the cutting edge. With a 1\/8-inch shank diameter, this bit fits standard drill chucks and CNC micro-drilling spindles used by machinists and electronics fabricators.\u003c\/p\u003e\u003cp\u003eThis bit is suited for precision drilling in cast iron, non-ferrous metals, alloy steel, carbon steel, stainless steel, high-temperature alloy, and titanium. The 35-degree helix angle and fast spiral configuration are well matched to materials that demand quick chip clearance to prevent work hardening or tool binding. It is commonly used in light machining, prototyping, and PCB manufacturing environments where hole diameter consistency and tight tolerances are required. The right-hand cutting direction is standard for conventional drill press and CNC spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 68 wire gauge size — 0.0310 inches (0.79 mm) decimal diameter\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle for clean entry on hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eFast spiral flute with 35-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter drilling\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds cutting-edge strength\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, uncoated — diameter tolerance held to -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling addition for CNC micro-drilling spindles, drill presses, and PCB drilling machines that accept a 1\/8-inch shank diameter.

Carbide bits are brittle — avoid lateral loading, side pressure, or interrupted cuts that can cause chipping or fracture. Ensure the spindle and collet are clean and concentric before seating the shank. Confirm machine RPM and feed rate are appropriate for the workpiece material and hole diameter before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.79 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\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: 1\/8 inch (0.1250 inches \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1\/4 inch (0.2500 inches \/ 6.35 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: 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\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\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0003 to +0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel, Alloy Steel, Carbon Steel, High Temperature Alloy, Stainless Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 302\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 30203100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51731154043186,"sku":"30203100","price":19.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1bc4d956256abeb31166caebfc994b3_cd877e47-0f8f-4520-a618-bd8ef9035871.jpg?v=1788727657","url":"https:\/\/voomisupply.com\/products\/m-a-ford-30203100-circuit-board-drill-bit-no-68","provider":"Voomi Supply","version":"1.0","type":"link"}
