It measures 0.228 inches in diameter (Wire Size 1) with an overall length of 2-7\/16 inches and a flute length of 1-5\/16 inches. The bit is manufactured from high-speed steel and features a standard 118-degree point angle with web thinning for reduced thrust and easier penetration. The bright, uncoated finish suits standard-speed operations without coolant. Machinists, tool-and-die technicians, and maintenance trades install this bit in screw machines, drill presses, and hand-held drilling equipment.\u003c\/p\u003e\u003cp\u003eThe 48701 is suited for drilling cast iron, non-ferrous metals, and steel in production and maintenance environments. Its screw machine length profile, shorter than jobber length, provides added rigidity and reduced deflection in close-tolerance work. The 2-flute spiral design promotes chip evacuation during through-hole and blind-hole operations. This bit fits standard straight-shank collets and chucks common across screw machines and benchtop drilling equipment in light manufacturing and fabrication shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire Size 1 diameter of 0.228 inches with a tight tolerance of +0.0000 to -0.0007 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for cast iron, non-ferrous metal, and steel\u003c\/li\u003e\n\u003cli\u003eScrew machine length body for increased rigidity and reduced runout\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for general-purpose dry or low-speed cutting\u003c\/li\u003e\n\u003cli\u003eParallel web configuration with regular spiral flute for consistent chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement screw machine drill bit compatible with standard straight-cylindrical shank collets and drill chucks used in screw machines, drill presses, and similar machine tool setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and bit changes should be performed with the machine powered off and the spindle fully stopped. Secure the straight-cylindrical shank firmly in a properly sized collet or chuck to the manufacturer-specified torque for that chuck model. Confirm workpiece is clamped before beginning a drilling cycle. Coolant-through operation is not supported on this bit; use appropriate cutting fluid applied externally when required by the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.228 inches (Wire Size 1)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0007 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 0.0217 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: 48701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51749800313138,"sku":"48701","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c7dc2561000783ee93138b271553af1.jpg?v=1788910648","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-48701-screw-machine-drill-bit-0-228-in","provider":"Voomi Supply","version":"1.0","type":"link"}
