Manufactured from high speed steel with a bright uncoated finish, this bit carries a 118-degree standard point angle and a two-flute spiral configuration that promotes efficient chip evacuation. The straight cylindrical shank seats securely in standard drill chucks, and the web-thinned point reduces thrust requirements at entry. At 3.25 inches overall length with a 1.875-inch flute length, the screw machine format is optimized for close-clearance work in turret lathes, screw machines, and CNC production drilling setups.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for general-purpose production drilling in cast iron, non-ferrous metals, and steel. The shorter-than-jobber body length improves rigidity and reduces deflection when drilling at high feed rates or in short-stroke machine setups. Machinists, toolroom technicians, and production line operators working with automatic screw machines or turret lathes will find the Series 157 format a standard fit for those operations. Right-hand cutting direction is standard for conventional drill press and machine tool spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter W size: 0.386 inches diameter with a tolerance of +0.0000 to -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, parallel web configuration\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect hole tolerance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body improves rigidity over standard jobber length\u003c\/li\u003e\n  \u003cli\u003eISO standard compliance; Series 157 designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with standard straight-shank drill chucks used in turret lathes, automatic screw machines, drill presses, and CNC machining centers.

Power down and lock out the machine before changing bits. Verify spindle speed is appropriate for the workpiece material and bit diameter before engaging the feed. Confirm the chuck bore is free of chips and burrs to maintain accurate bit seating and prevent runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal)\u003c\/strong\u003e: 0.386 inches\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\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eCoolant Through\u003c\/strong\u003e: No\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 Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 157\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: 0.0817 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: 48823\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51731773817138,"sku":"48823","price":16.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a1d6fa9a0302e6e8ab99d2fe41885d8.jpg?v=1788734791","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48823-screw-machine-drill-bit-w-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
