Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it measures 11\/32 inch (0.3438 inch) in diameter with a 4-3\/4 inch overall length and a 3-7\/16 inch flute length. The 118-degree standard point angle and regular spiral flute geometry suit common metal-removal applications. The web-thinned, tapered web reduces thrust and improves chip evacuation. This bit is part of the Series 150L line and is used by machinists, pipefitters, and maintenance technicians who require left-hand cutting direction for broken fastener extraction or reverse-rotation drilling setups.\u003c\/p\u003e\n\u003cp\u003eLeft-hand drill bits are most commonly used to extract broken bolts, studs, and screws in metal workpieces. As the bit contacts the fastener under reverse rotation, the cutting force often backs out the broken piece before a full hole is drilled. This makes the 44422 a standard tool in industrial maintenance shops, commercial HVAC service, and plumbing rough-in work where broken fasteners in cast iron or steel must be removed without damaging the surrounding material. The straight-cylindrical shank is compatible with standard drill chucks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction for broken fastener extraction under reverse rotation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for drilling cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for broad material compatibility\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard 3-jaw drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for general-purpose drilling in cast iron and steel workpieces.

Power down and de-energize any equipment before drilling into it for fastener extraction. Secure the workpiece firmly before drilling to prevent movement. Follow applicable shop safety standards and wear appropriate eye protection when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 inch (0.3438 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 11\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eCoolant Throughstrong\u0026gt;: No\u003c\/strong\u003e\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51733488599346,"sku":"44422","price":24.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a013d62ccf40324286d455fe7a5e50dc.jpg?v=1788755823","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44422-jobber-drill-bit-11-32-in-left-hand-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
