Built from cobalt tool steel with a straw finish, this bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard or curved surfaces. The spiral flute geometry with a web-thinned, tapered web configuration promotes efficient chip evacuation. At 6 inches overall length with a 1.25-inch flute length, it is suited to aerospace-style and structural drilling tasks performed by machinists, aircraft mechanics, and metalworking tradespeople.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for general-purpose metalworking where extended reach is required, such as drilling through structural steel, aluminum, and other metals in confined or obstructed areas. It is sized at 3\/32 inch (0.0938 inch decimal) with a straight-cylindrical shank of matching diameter, making it compatible with standard drill chucks and right-angle drill attachments commonly used in sheet metal and structural fabrication work. Typical applications include airframe assembly, HVAC duct framing, electrical enclosure drilling, and light structural work where cobalt hardness is needed to maintain cutting edge life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt tool steel construction provides heat resistance and edge retention when drilling hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering, eliminating the need for a center punch on most metals\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust force and improves chip clearance\u003c\/li\u003e\n\u003cli\u003e6-inch overall length delivers extended reach into deep or obstructed workpieces\u003c\/li\u003e\n\u003cli\u003eStraw finish indicates heat-treated cobalt steel and helps with light lubrication retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, two-flute spiral geometry for standard drill press and handheld use\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard 3\/32-inch straight-cylindrical shank drill chucks and right-angle drill attachments used in metalworking and structural applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists, aircraft mechanics, or metalworking tradespeople using appropriate drilling equipment. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before drilling. Use appropriate cutting fluid for harder metals to extend tool life and reduce heat buildup. Inspect the cutting edges before use and replace the bit if chipping or deformation is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 3\/32 inches (0.0938 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/32 inches (0.0938 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eSelf-Centering\u003c\/strong\u003e: Yes\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 Performance\u003c\/strong\u003e: General Purpose\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: 0.04 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.E06.0238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748019667250,"sku":"C.E06.0238","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e87215ce8e587be330c67fdbf16f8eb7.jpg?v=1788888107","url":"https:\/\/voomisupply.com\/products\/hertel-c-e06-0238-aircraft-extension-drill-bit-3-32-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
