The 135-degree split point tip is self-centering and web-thinned, reducing walking and cutting thrust on entry without a pilot hole. The oxide finish provides moderate lubricity and corrosion resistance during use. With a 4.5-inch flute length and 12-inch overall length, this bit reaches into recessed or deep workpiece areas that standard-length drills cannot access. It is installed and operated by machinists, aircraft mechanics, and maintenance technicians working with drill motors or drill presses.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for through-drilling in aluminum, mild steel, and similar materials encountered in aircraft structural panels, frames, and general fabrication work. The extended reach makes it practical for drilling through stacked materials or into confined spaces where a standard jobber-length bit falls short. The right-hand spiral flute geometry clears chips efficiently during extended cuts. Series 500-12 designates it as part of a product family of aircraft extension drills built to NAS 907 Type B standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point for self-centering entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web construction reduces cutting thrust and feed force\u003c\/li\u003e\n\u003cli\u003e4.5-inch flute length accommodates deep-hole and stacked-material drilling\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach into recessed work areas\u003c\/li\u003e\n\u003cli\u003eOxide finish for light corrosion resistance and reduced friction during cutting\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eBuilt to NAS 907 Type B standards; designed as an OEM-style replacement or direct substitute for 1\/2-inch aircraft extension drill bits in Series 500-12 applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAircraft mechanics and machinists should secure the workpiece firmly before drilling and ensure the drill motor or press is rated for the shank diameter before use. Power down all equipment before changing or inspecting bits. Proper cutting fluid or lubrication is recommended when drilling ferrous materials to preserve tool life. Follow applicable workplace safety and aviation maintenance standards when performing structural drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 500-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.167 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6001318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51695600632114,"sku":"6001318","price":72.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00c62afe4afb4c768fcc83692ac48d80_c88fb96c-b3b2-4974-b9ca-21def56ade03.jpg?v=1788336805","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001318-1-2-in-aircraft-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
