Built to Series 501-12 specifications, it features a 135-degree split point that is self-centering and web-thinned, reducing the force needed to start a hole without a center punch. The 0.201-inch (Wire Size #7) straight-cylindrical shank pairs with the spiral flute geometry to evacuate chips efficiently. An oxide finish provides a baseline level of surface protection. Licensed HVAC, aviation, and general metal fabrication technicians working with structural assemblies, panels, and tubing will find this bit suited to production and field work alike.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for general-purpose metal drilling in applications requiring extended reach, such as drilling through aircraft structures, HVAC sheet metal panels, electrical enclosures, and plumbing supports where standard-length bits cannot reach the target bore. The 12-inch overall length and 2.4375-inch flute length give the operator clearance to work in confined or recessed spaces. The right-hand cutting direction and two-flute spiral configuration are standard for ferrous and non-ferrous metals encountered in trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point is self-centering and web-thinned for reduced starting pressure\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length provides extended reach for confined or deep-access drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous and non-ferrous metal\u003c\/li\u003e\n  \u003cli\u003e0.201-inch diameter straight-cylindrical shank fits standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eOxide finish for basic corrosion and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard drill chucks accepting a 0.201-inch straight-cylindrical shank.

Secure the workpiece firmly before drilling to prevent walking or deflection, particularly when using the extended length. Apply appropriate cutting fluid when drilling harder metals to extend bit life and maintain tolerances. Inspect the split point for chipping or wear before each use and replace the bit if the cutting edges show degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: #7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.201 inches\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: 2.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.201 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 501-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907 Type B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.083 pounds\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6001445\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51693006553394,"sku":"6001445","price":30.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da3496e4617881f200db3c68936287ae_16763cfa-4af5-4dfa-932a-f48014d5cc27.jpg?v=1788306120","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-6001445-aircraft-extension-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
