It features a No. 29 wire gauge diameter of 0.1360 inches (3.45 mm), a 118-degree split-point angle, and a fast spiral flute geometry that promotes efficient chip evacuation at high spindle speeds. The bright polished finish reduces friction and heat buildup during operation. With an overall length of 1.5 inches and a flute length of 0.75 inches, this bit is sized for compact, controlled drilling where positional accuracy is critical. It is typically installed and used by machinists, electronics technicians, and precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron, non-ferrous metals, and steel, making it a versatile choice beyond dedicated PCB work. The tapered web configuration adds rigidity and reduces the risk of bit deflection in tight-tolerance applications. The right-hand cut and 35-degree helix angle are optimized for clean entry and exit holes in thin and medium-thickness materials. It is commonly used in production shop environments, electronics assembly, and prototype fabrication where consistent hole diameter and finish quality are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 29 wire gauge diameter: 0.1360 inches (3.45 mm) for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle suited for cast iron, steel, and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for hardness, wear resistance, and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with 35-degree helix angle promotes rapid chip removal\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and heat at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength and resists deflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit compatible with standard drill chucks and CNC drilling equipment accepting a 0.1360-inch shank diameter.

Ensure the spindle and workpiece are secured before operation. Use appropriate cutting speeds for solid carbide tooling and the specific material being drilled. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed to maintain hole quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 29\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.45 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 3.45 mm\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\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 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 30013600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746227683634,"sku":"30013600","price":27.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae5c1b036859523d15cdd579d09011ae.jpg?v=1788867371","url":"https:\/\/voomisupply.com\/products\/hertel-30013600-circuit-board-drill-bit-size-29-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
