Built from high-speed steel (HSS) with a bright, uncoated finish, it features a left-hand cutting direction and a standard 118-degree drill point angle. The 11\/32 inch (0.3438 inches) diameter straight shank matches the bit diameter, keeping chuck setup straightforward. With an overall length of 3 inches and a flute length of 1.6875 inches, this stub-length bit provides added rigidity compared to jobber-length alternatives, reducing deflection in production drilling applications. It carries Series 157L designation and conforms to ISO standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling aluminum, copper, magnesium, thermoplastics, wood, and slate. The left-hand cut makes it particularly useful for removing broken fasteners and studs, as the cutting torque tends to back out a stuck piece as the bit contacts it. Electricians, HVAC techs, and general tradespeople working with soft metals or plastic conduit bodies will find this useful at the bench or in a drill press setup. The screw machine length format is common in production environments where a shorter bit reduces chatter and improves hole accuracy in repetitive operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLeft-hand cutting direction aids broken fastener extraction\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned geometry for easier starting\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 3 inches OAL increases rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 0.3438 inches diameter fits standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — compatible with cutting fluids or dry drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard drill presses and hand drills accepting a straight shank.

Ensure the workpiece is securely clamped before drilling to prevent rotation or movement. For left-hand bits, the drill must be set to reverse rotation. Apply appropriate cutting fluid when drilling copper or aluminum to extend bit life and improve hole finish.\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 inches (0.3438 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6875 inches (1-11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3438 inches (8.73 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\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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inches\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\u003eWeight\u003c\/strong\u003e: 0.0621 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: 48922\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51728241754418,"sku":"48922","price":25.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44d419b24626b447e32ebea48ecbc601.jpg?v=1788690021","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48922-screw-machine-drill-bit-11-32-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
