Built from high-speed steel (HSS) with a bright uncoated finish, it features a 118-degree standard point angle and a web-thinned, parallel-web configuration for reduced thrust and cleaner entry. The 11\/64-inch (0.1719-inch) diameter and compact 2-1\/8-inch overall length make it well suited for confined spaces and short-stroke machine spindles. Two regular spiral flutes clear chips efficiently, and the straight shank seats directly in standard drill chucks. This bit is a general-purpose tool intended for machinists, maintenance technicians, and production floor personnel.\u003c\/p\u003e\u003cp\u003eThe 48911 is suited for screw machine operations, CNC drilling centers, and benchtop drill press work where a shorter flute length reduces deflection and improves hole accuracy. Primary workpiece materials include aluminum, copper, magnesium, slate, thermoplastic, and wood. The left-hand cutting direction is particularly useful when removing broken fasteners or drilling out left-hand-threaded components, as rotational force tends to back out the fastener during the drilling process. The 1-1\/16-inch flute length and 1-1\/16-inch shank length keep chip evacuation manageable in shallow-depth applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cut for broken fastener extraction and left-hand threaded applications\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle works across a broad range of general-purpose materials\u003c\/li\u003e\n\u003cli\u003eHSS construction with bright uncoated finish suitable for non-ferrous metals, plastics, and wood\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2-1\/8 inches OAL) minimizes deflection in short-stroke setups\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose replacement or production drill bit for screw machine and short-bed drilling applications where a 0.1719-inch left-hand HSS bit with a straight shank is specified.

Secure the workpiece firmly before drilling to prevent spin-out, particularly important with left-hand rotation. Use appropriate cutting fluid or lubricant when drilling copper or aluminum to extend tool life and improve finish quality. Inspect the point for wear before each use; a dull or chipped point will cause oversized holes and excess heat.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 11\/64 inches (0.1719 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/16 inches (1.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-1\/16 inches (1.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1719 inches (4.37 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Aluminum, Copper, Magnesium, Slate, Thermoplastic, Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 157L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0117 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: 48911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747513041202,"sku":"48911","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1488c23bfd0a7e6eaf0ff3b2046d5b1.jpg?v=1788881653","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48911-screw-machine-drill-bit-11-64-in-lh-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
