Built from high-speed steel (HSS) with a bright, uncoated finish, it measures 15\/32 inches (0.4688 inches) in diameter and 3-5\/8 inches overall length. The 118-degree standard point angle and web-thinned geometry reduce entry resistance and improve chip evacuation. With a regular spiral flute and straight shank, this bit mounts in standard drill chucks and screw machine setups. Machinists, tool and die techs, and maintenance professionals typically reach for this bit when left-hand extraction of broken fasteners or reverse-drilling operations are required.\u003c\/p\u003e\u003cp\u003eThe 48930 is suited for drilling aluminum, copper, magnesium, slate, thermoplastic, and wood. Its screw machine length body keeps the drill compact for use in tight setups and production environments where rigidity and short stick-out matter. The left-hand cutting direction also makes it a practical choice when used alongside left-hand taps or for backing out damaged screws without additional extraction tooling. Shank diameter matches the drill diameter at 0.4688 inches, providing consistent chuck engagement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand cutting direction for reverse drilling and broken fastener removal\u003c\/li\u003e\n\u003cli\u003eHSS construction with bright, uncoated finish for general-purpose performance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for reduced thrust\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute, 2-1\/8 inches flute length, promotes smooth chip flow\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 3-5\/8 inches OAL for compact, rigid setups\u003c\/li\u003e\n\u003cli\u003eStraight shank at 0.4688 inches diameter fits standard drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard straight-shank drill chucks and screw machine drill presses.

Secure the straight shank firmly in the drill chuck before operation to prevent slipping under cutting load. Left-hand bits require the spindle to run in reverse; confirm spindle direction before engaging the workpiece. Eye protection and appropriate work-holding are required per standard shop safety practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 15\/32 inches (0.4688 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-1\/8 inches (2.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4688 inches (11.91 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1344 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: 48930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51737036521778,"sku":"48930","price":39.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4aa173d588c452acd3833e522b1a8fa.jpg?v=1788783469","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48930-screw-machine-drill-bit-15-32in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
