With a 1\/8 inch (0.125 inch) diameter, a 118-degree drill point angle, and a fast spiral geometry, this bit delivers accurate hole placement with minimal material delamination. The tapered web configuration reinforces the cutting tip, and the bright polished finish reduces friction during cutting. It is suited for use by machinists, electronics technicians, and trade professionals who require repeatable, tight-tolerance results in small-diameter drilling operations.\u003c\/p\u003e\u003cp\u003eThis bit is built for drilling cast iron, non-ferrous metals, and steel, making it useful across PCB work, light fabrication, and precision machining tasks. The 5\/8 inch flute length and 1-1\/2 inch overall length make it compatible with standard drill press chucks and CNC spindles that accept 1\/8 inch shank tooling. The right-hand cutting direction and 35-degree helix angle are optimized for chip evacuation in both ferrous and non-ferrous materials. This bit is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in precision drilling\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for accurate, low-thrust entry\u003c\/li\u003e\n\u003cli\u003eFast spiral with 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTapered web configuration strengthens the cutting tip\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and heat buildup during operation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard drill presses and CNC spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill presses, CNC drilling machines, and hand-held rotary tools that accept 1\/8 inch shank drill bits.

Ensure the drill press or CNC spindle is fully powered down and secured before changing tooling. Verify chuck or collet compatibility with the 1\/8 inch shank diameter before use. Do not exceed the recommended feed rate or spindle speed for the workpiece material, as carbide tooling is brittle and susceptible to breakage under lateral loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inch \/ 3.18 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\u003c\/strong\u003e: 1\/8 inch (0.125 inch \/ 3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5\/8 inch (0.625 inch \/ 15.88 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\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: -0.0005 to +0.0000 inch\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\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metals, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 30012500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730729337138,"sku":"30012500","price":26.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e768aacab2873a9d52b8b6eed7d26a0.jpg?v=1788721821","url":"https:\/\/voomisupply.com\/products\/hertel-30012500-circuit-board-drill-bit-1-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
