Built from high speed steel with a bright, uncoated finish, it cuts a 0.199-inch diameter hole equivalent to wire size 8. The 118-degree standard point angle suits a wide range of workpiece materials, while the web-thinned tip reduces thrust and improves penetration. The two-flute spiral design evacuates chips efficiently during short-hole drilling operations. At 2.25 inches overall length, this stub-style bit fits into tight clearances where jobber-length bits cannot. Licensed machinists, maintenance technicians, and toolroom operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for drilling cast iron, non-ferrous metals, and steel in screw machine, CNC, and manual drill press applications. The short flute length of 1.1875 inches and rigid body make it the standard choice when chatter or deflection is a concern in production drilling. The straight-cylindrical shank seats directly in standard chucks and collets without adapters. It falls within the Series 157 line, which covers general-purpose stub-length HSS bits in the 0.1500 to 0.2000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.199-inch diameter with a tight tolerance of +0.0000 to -0.0007 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across cast iron, steel, and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web tip reduces entry thrust and improves point stability\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle — compatible with conventional drill press and CNC setups\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body resists deflection in short-hole and production drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix promotes reliable chip evacuation\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 for use in standard three-jaw chucks and collet systems accepting straight-cylindrical shanks.

Always power down and lock out the machine before changing bits. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, noting that this bit does not support through-coolant delivery. Inspect the cutting edges and web area for wear or chipping between uses to maintain hole-size tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.199 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 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\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: 0.0159 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: 48708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749228904754,"sku":"48708","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f20f09135edf11cdd214be7da94ad385.jpg?v=1788903378","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48708-screw-machine-drill-bit-0-199-in","provider":"Voomi Supply","version":"1.0","type":"link"}
