It measures 27\/64 inch (0.4200 inch) in diameter with an overall length of 3-3\/8 inches and a flute length of 2 inches. The bit is manufactured from high speed steel with a coated finish for added wear resistance. A 135-degree split point reduces walking on entry and lowers thrust requirements compared to a standard 118-degree point. Web thinning with a parallel web configuration further improves chip clearance and cutting efficiency. This is a professional-grade tool suited for machine shop and trade applications where consistent hole quality in ferrous materials is required.\u003c\/p\u003e\u003cp\u003eThe 48227 is designed for screw machine length applications where a shorter, stiffer bit is preferred over jobber length. Its reduced overhang improves rigidity, making it well suited for drill press, CNC machining center, and production drilling operations. Primary workpiece materials are cast iron and steel. The straight cylindrical shank is compatible with standard drill chucks and collet holders. Series 2159 indicates this bit conforms to CHICAGO-LATROBE heavy-duty specifications and meets NAS 907 and ISO standards for dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e27\/64 inch diameter with a tight tolerance of +0.0000 to -0.0010 inch for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and prevents bit walking\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eScrew machine length body provides added rigidity over standard jobber length bits\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute configuration promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 and ISO standards; Series 2159 heavy-duty designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron and steel workpieces.

Secure the shank fully in the chuck or collet and verify concentricity before operation. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, noting that this bit does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 27\/64 inch (0.4200 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eTool Performance\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0010 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: NAS 907, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2159\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 48227\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51727798010162,"sku":"48227","price":27.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1043d01225245e5e23663826afaae87.jpg?v=1788682574","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48227-screw-machine-drill-bit-27-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
