With a 1\/32 inch (0.0312 inch decimal) cutting diameter and a 130-degree drill point angle, it produces clean entry holes with minimal breakout. The fast spiral flute geometry and 35-degree helix angle promote efficient chip evacuation in shallow-depth holes. The bright polished finish reduces friction and heat buildup during operation. This bit is intended for use by machinists, electronics technicians, and skilled tradespeople who require repeatable hole geometry in small-diameter work.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision drilling in alloy steel, carbon steel, cast iron, high temperature alloy, stainless steel, and titanium. It fits applications where a 1\/8 inch shank diameter is required for collet or chuck compatibility. The 1\/4 inch flute length and 1-1\/2 inch overall length make it appropriate for shallow-depth circuit board and fine metalworking operations where bit rigidity and runout control are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle optimized for circuit board and thin-material drilling\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute design with 35-degree helix angle for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds strength at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eBright polished finish minimizes friction and heat generation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; compatible with standard drill chucks and collets accepting 1\/8 inch shanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision replacement or stock drill bit for any drill press, CNC drilling machine, or hand-held rotary tool equipped with a collet or chuck accepting a 1\/8 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or technician familiar with small-diameter carbide tooling. Always secure the workpiece firmly before drilling to prevent bit deflection or breakage. Carbide bits are brittle and should not be used with excessive side pressure or in applications that produce lateral loading. Inspect the bit for chips or cracks before each use and replace if any damage is detected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 1\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (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\u003eShank Diameter (Inch)\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 3.18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Inch)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (Decimal Inch)\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length (mm)\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (Inch)\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Carbon Steel, Cast Iron, High Temperature Alloy, Stainless Steel, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 pounds\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30203120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737032982834,"sku":"30203120","price":16.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/198f74cad0ab3fc1794102f54cb7554f.jpg?v=1788783415","url":"https:\/\/voomisupply.com\/products\/hertel-30203120-circuit-board-drill-bit-1-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
