Built from high speed steel with a bright, uncoated finish, it measures 5\/64 inch (0.0781 inches) in diameter and carries an overall length of 1-11\/16 inches. The 118-degree standard point angle and two-flute spiral configuration deliver clean entry and efficient chip evacuation. The web-thinned, parallel web design reduces thrust requirements at the point. This bit fits standard straight-cylindrical chucks and is suited for use by machinists, maintenance technicians, and trade professionals working in production or field environments.\u003c\/p\u003e\n\u003cp\u003eThe 48905 is built for drilling into non-ferrous and soft materials including aluminum, copper, magnesium, thermoplastics, wood, and slate. Its screw machine length profile provides added rigidity compared to jobber-length bits, making it well suited for close-tolerance work in drill presses, CNC machines, and hand-held equipment where shorter bit overhang improves accuracy. The left-hand cutting direction makes this bit particularly useful for removing broken fasteners or working in reverse-spindle applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand spiral flute cuts in reverse rotation for broken-fastener extraction and reverse-spindle use\u003c\/li\u003e\n  \u003cli\u003e5\/64 inch diameter with a tight tolerance of +0.0000 to -0.0005 inches for close-fit holes\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces point thrust and improves penetration in soft materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across general-purpose drilling tasks\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suited for use without coolant on non-ferrous and soft workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for general-purpose screw machine length applications in straight-cylindrical chuck tooling.

Ensure the drill press or hand tool spindle is set to reverse rotation to engage the left-hand cutting direction correctly. Inspect the bit for damage before each use and replace if chipping or deformation is observed. No coolant feed is required for this bit; use appropriate speeds and feeds for the workpiece material per standard machining practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/64 inch (0.0781 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11\/16 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\u003eCutting Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Parallel Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 157L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0024 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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51736755896626,"sku":"48905","price":77.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ffadfe332907fa8035c19da0c3f9132.jpg?v=1788779971","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48905-screw-machine-drill-bit-5-64-in-lh","provider":"Voomi Supply","version":"1.0","type":"link"}
