Built from high speed steel with a bright, uncoated finish, this bit measures 7\/64 inch (0.1094 inches) in diameter and features a standard 118-degree point angle. The shorter screw machine body length provides added rigidity compared to jobber-length bits, reducing deflection in tight setups. Two spiral flutes with a web-thinned, parallel web configuration promote chip evacuation and reduce thrust during entry. The straight-cylindrical shank seats securely in standard drill chucks.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling aluminum, copper, magnesium, slate, thermoplastic, and wood. The left-hand cutting direction makes it particularly useful for extracting broken fasteners and studs — as the bit bites into the material, reverse torque backs the fastener out without requiring additional extraction tools. The screw machine length (1-13\/16 inches overall, 13\/16-inch flute length) fits well in drill presses, CNC turret setups, and hand drills where shorter tool projection is preferred. The Series 157L meets ISO standards for dimensional consistency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand spiral cut aids broken fastener extraction under reverse rotation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles a broad range of non-ferrous and non-metallic materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web reduces drilling thrust and improves point penetration\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for consistent fit in close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup concerns when regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill chucks accepting a straight-cylindrical shank.

Secure the straight-cylindrical shank fully in the chuck jaws before starting. Left-hand bits require the drill set to reverse rotation — confirm direction before engaging the workpiece. Inspect the cutting edges and web for wear or chipping before each use; a dull or chipped bit generates excess heat and can damage both the workpiece and the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\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: 0.0044 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: 48907\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51752283898162,"sku":"48907","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/837dcc087ba596d14a28dc1517f1d5a2.jpg?v=1788927158","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48907-screw-machine-drill-bit-7-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
