The bit measures 1\/8 inch (0.1250 inch decimal) in diameter with an overall length of 6 inches, making it well suited for reaching into recessed or confined areas that standard-length bits cannot access. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on hard surfaces. A straw finish indicates the cobalt content and helps manage heat during extended cutting operations. Two spiral flutes evacuate chips efficiently, and the tapered web configuration with web thinning reduces thrust force required at the drill press or hand drill.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for use on aluminum, stainless steel, titanium, and other hard or abrasive materials common in aircraft maintenance, fabrication shops, and heavy industrial settings. The 6-inch overall length suits applications where standard jobber-length bits lack the reach, such as drilling through structural members, frame components, or layered sheet stock. The straight cylindrical shank accepts standard drill chucks. General-purpose tool performance and right-hand cutting direction make it compatible with conventional drill presses, magnetic drills, and hand-held power tools used by aviation mechanics, machinists, and maintenance technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with straw finish for heat resistance in hard-metal drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point is self-centering, reducing drill walk on hard surfaces\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides reach into deep or confined workspaces\u003c\/li\u003e\n  \u003cli\u003e1-5\/8 inch (1.6250 inch decimal) flute length with spiral, two-flute design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and operator fatigue\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type J standard for aircraft-grade drill bit performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style aircraft extension drill bit in the CO500-6 series, suitable for use in standard straight-shank drill chucks across drill presses, magnetic base drills, and hand-held power tools requiring a 1\/8-inch bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit should follow standard machining safety practices. Secure the workpiece firmly before drilling and ensure the chuck is properly tightened onto the straight cylindrical shank. Eye protection and appropriate chip guards are required when drilling hard metals. Allow adequate chip clearing during deep drilling operations to prevent flute packing and bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\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: 1-5\/8 inches (1.6250 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\u003ePoint Type\u003c\/strong\u003e: Split, Self-Centering\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\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 Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CO500-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: NAS 907 Type J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5995818\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51690659381554,"sku":"5995818","price":15.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0880f1329575db98adcdd4da25c6922a_0b2d9e24-5aab-4557-ac90-55cbe99cb755.jpg?v=1788273525","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995818-aircraft-drill-bit-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
