It is manufactured from high-speed steel with a bright uncoated finish and carries a wire gauge size of 43, corresponding to a decimal diameter of 0.0890 inches. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve centering on ferrous workpieces. With an overall length of 2.25 inches and a flute length of 1.25 inches, this bit fits standard drill chucks and reversible drill motors commonly used by machinists, pipefitters, and maintenance technicians.\u003c\/p\u003e\u003cp\u003eThis bit is suited for drilling into cast iron and steel in situations where left-hand rotation is required, such as removing broken fasteners or drilling with a reversing drill motor. The straight-cylindrical shank with a diameter of 0.0890 inches seats securely in keyless or keyed chucks without slippage. It is a Series 150L general-purpose tool intended for both shop and field use where a small-diameter, left-hand bit is needed in light metalworking or mechanical service tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for use with reversing drill motors and broken-fastener extraction\u003c\/li\u003e\n\u003cli\u003eWire size 43 (0.0890 inches) with a diameter tolerance of -0.0005 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and self-centering entry\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with bright uncoated finish suitable for cast iron and steel\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 2 flutes for efficient chip evacuation in short-hole drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose left-hand jobber-length drill bit for use in standard reversible drill motors and drill presses that accept straight-cylindrical shanks.

Ensure the drill motor is set to reverse rotation before seating the bit, as left-hand bits require counterclockwise spindle direction to cut. Secure the workpiece firmly before drilling to prevent movement. Do not exceed the recommended feed rate for the bit diameter, and use appropriate cutting fluid when drilling steel to extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 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: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Bit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\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\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\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: 150L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0035 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: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44513\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727793291570,"sku":"44513","price":88.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb93a21312cfdd2cbd1d60fde5e8d1b2.jpg?v=1788682483","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-44513-jobber-drill-bit-wire-43-left-hand-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
