Built to a 12-inch overall length with a 1\/16-inch diameter and a 135-degree split point, this bit centers itself on contact and reduces walking on hard or curved surfaces. The straw finish cobalt construction provides added heat resistance and edge retention when drilling through high-strength alloys, stainless steel, and hardened materials. Two spiral flutes and a web-thinned, tapered web design promote efficient chip evacuation during extended drilling passes.\u003c\/p\u003e\u003cp\u003eThis aircraft extension bit is intended for professional use in aerospace maintenance, structural assembly, and industrial fabrication where standard-length bits cannot reach. The 12-inch reach allows access to recessed fastener holes and blind locations in aircraft frames, structural steel, and heavy equipment panels. With a straight-cylindrical shank measuring 1\/16 inch in diameter, it seats securely in standard drill chucks and right-angle drill adapters common in trade and MRO environments. Right-hand cutting direction is standard for conventional drill press and hand-drill operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool material with straw finish for heat resistance and extended tool life in hard alloys\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering and reduces drill walking without a center punch\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach into deep or recessed drilling locations\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust load and improves chip flow\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes with 7\/8-inch flute length for efficient chip evacuation on small-diameter cuts\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft extension drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit for use with standard drill chucks and right-angle adapters accepting a 1\/16-inch straight-cylindrical shank.

Secure the straight-cylindrical shank fully in the drill chuck before use and verify runout is within acceptable limits to avoid bit breakage at this diameter. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened alloys to preserve edge life. Inspect the bit for chipping or wear before each use, as small-diameter cobalt bits are susceptible to breakage under side-load or misalignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 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: 7\/8 inch (0.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-Centering\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: C.E07.0159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730578276658,"sku":"C.E07.0159","price":32.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/144534076bcf165c3c937f4232380287.jpg?v=1788719832","url":"https:\/\/voomisupply.com\/products\/hertel-c-e07-0159-aircraft-extension-drill-bit-1-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
