It is manufactured from high-speed steel (HSS) with a bright, uncoated finish and features a standard 118-degree point angle with a web-thinned tip for improved penetration. The overall length is 5.5 inches, with a 4.0625-inch flute length and a 0.4375-inch straight shank diameter. The two-flute, regular-spiral design promotes efficient chip evacuation. This bit is suited for use by machinists, HVAC technicians, plumbers, and electricians performing metal drilling tasks during fabrication or service work.\u003c\/p\u003e\u003cp\u003eThe 5995511 is intended for drilling through steel and cast iron in both residential and light commercial applications. Its left-hand cutting direction makes it particularly useful when attempting to extract broken fasteners, as the rotation can back out a seized screw or bolt while drilling. The Series L10 designation places it within a standard jobber-length product family conforming to ANSI specifications. It is a single-piece, general-purpose tool appropriate for use in a standard drill press or hand drill with a compatible chuck.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction aids in broken fastener extraction\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for cleaner entry\u003c\/li\u003e\n\u003cli\u003eHSS construction handles steel and cast iron at typical drilling speeds\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect hole tolerance\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design supports consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eANSI-compliant Series L10 jobber-length construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any standard drill press or hand drill equipped with a chuck that accepts a 0.4375-inch straight shank.

Secure the straight shank fully in the chuck before operation and confirm chuck key is removed before starting the drill. Use appropriate cutting fluid or coolant when drilling harder metals to preserve cutting edge life. Always wear eye protection and follow applicable shop safety standards when operating rotary cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: L10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\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: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.94 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: 5995511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691504042290,"sku":"5995511","price":48.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/700097b531762e7d1f9969c9cacad3be_5eed2176-38ae-498a-b2bb-0a3972f12e18.jpg?v=1788286103","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995511-7-16-inch-hss-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
