It features a 130-degree drill point angle, a fast spiral flute geometry, and a tapered web configuration designed to evacuate chips efficiently in printed circuit board and precision drilling applications. The 1\/8-inch (0.1250-inch) shank diameter fits standard collet chucks on CNC drill presses and high-speed spindles. With a right-hand cutting direction and a 35-degree helix angle, the bit maintains accuracy and minimizes breakout on thin and layered workpieces. A bright polished finish reduces friction and heat buildup at the cutting edge.\u003c\/p\u003e\u003cp\u003eThis bit is suited for precision drilling in PCB fabrication, electronics assembly, and light machining environments where tight hole tolerances are required. The solid carbide construction also makes it capable of drilling alloy steel, carbon steel, cast iron, stainless steel, high-temperature alloys, and titanium in toolroom and production settings. It is typically run on CNC machining centers, dedicated PCB drill stations, or benchtop drill presses with collet tooling. The 3\/8-inch flute length and 1-1\/2-inch overall length make it appropriate for shallow, precise holes in flat stock and board materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e130-degree split-point geometry reduces walking and improves entry accuracy\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration adds strength at the cutting tip\u003c\/li\u003e\n\u003cli\u003eBright polished finish lowers friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in collet chucks accepting a 1\/8-inch (0.1250-inch) shank diameter.

Secure the shank fully in a matched collet or chuck before running the spindle. Carbide bits are brittle — avoid side loading, interrupted cuts at extreme feeds, or contact with hard fixtures. Set spindle speed and feed rate according to the workpiece material and manufacturer cutting data for the specific diameter; do not run carbide bits at speeds or feeds intended for high-speed steel tooling without adjustment.\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. 58\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0420 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 1.07 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\u003eShank Diameter (Inch)\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: 3\/8 inch (0.4000 inches)\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\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\u003eCoating \/ Finish\u003c\/strong\u003e: Bright Polished\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: 0.45 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30204200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748668244274,"sku":"30204200","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/922efc9013d884a0ce643dbc8cdbf4c5.jpg?v=1788896392","url":"https:\/\/voomisupply.com\/products\/hertel-30204200-circuit-board-drill-bit-no-58-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
