It measures 0.246 inches (Letter size D) in diameter with a 118-degree standard point angle, making it well suited for drilling into steel, iron, aluminum, and similar materials. The bit features a 2-flute spiral flute configuration with a regular spiral type and an oxide finish for basic lubricity and surface protection. Overall length is 2.5 inches with a flute length of 1.375 inches. Licensed machinists, tool-and-die technicians, and maintenance professionals typically use this bit in screw machine and drill press operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit fits standard screw machine length applications where a shorter overall length improves rigidity and reduces deflection. With a straight-cylindrical shank and ANSI specification designation, it is compatible with conventional drill chucks and collet holders found on drill presses, CNC machines, lathes, and screw machines. It covers the 0.200 to 0.250 inch drill bit size range and is graded for general-purpose use, making it a dependable choice for production and maintenance shops requiring consistent, accurate hole sizing at the 0.246-inch dimension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.246 inch (Letter D) diameter with 118-degree standard point angle for general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of metalworking applications\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides basic surface protection and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2.5 inches overall) improves rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with 3xD flute-to-diameter ratio promotes chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank is compatible with standard drill chucks and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or production drill bit for use in standard drill chucks and collet holders accepting straight-cylindrical shanks at the 0.246-inch diameter size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Ensure the drill press, lathe, or screw machine is fully powered down and secured before inserting or removing the bit from the chuck or collet. Verify chuck runout and shank seating before operation to maintain hole accuracy. Follow applicable shop safety practices and manufacturer guidelines for feed rate and speed selection based on the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.246 inches (Letter D)\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61699583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741763010866,"sku":"61699583","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccf40e0ec2b4b550a9ea6afaa2c8bea7.jpg?v=1788833347","url":"https:\/\/voomisupply.com\/products\/hertel-61699583-screw-machine-drill-bit-0-246-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
