It accepts interchangeable drill-tip inserts, allowing worn cutting heads to be swapped without replacing the entire tool body. The drill covers a diameter range of 1.063 to 1.098 inches and reaches a maximum drill depth of 5.31 inches, corresponding to a 5xD depth-to-diameter ratio. The 1.25-inch Weldon Flat shank provides positive rotational engagement in compatible toolholders. Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting chip evacuation and tool life in deep-hole applications. This tool is installed and operated by machinists and CNC programmers in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThe ISCAR 3203521 fits DCN A-5D style toolholder configurations and is suited for drilling applications in ferrous and non-ferrous materials where consistent hole diameter and depth repeatability are required. The replaceable-tip design reduces tooling costs and downtime in high-volume production runs. Compatible insert styles include FCP, HCP-IQ, ICK, ICM, and ICP tips, giving operators flexibility to match tip geometry to the specific workpiece material and cutting condition.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplaceable-tip design accepts FCP, HCP-IQ, ICK, ICM, and ICP insert styles\u003c\/li\u003e\n\u003cli\u003eDiameter range of 1.063 to 1.098 inches accommodates slight size variation across compatible tips\u003c\/li\u003e\n\u003cli\u003e5xD depth-to-diameter ratio with a maximum drill depth of 5.31 inches\u003c\/li\u003e\n\u003cli\u003eThrough-coolant construction channels fluid to the cutting edge for improved chip evacuation\u003c\/li\u003e\n\u003cli\u003e1.25-inch Weldon Flat shank provides secure, anti-rotation engagement in the spindle\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards for CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible insert styles: FCP, HCP-IQ, ICK, ICM, and ICP.

Ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state before changing inserts or mounting the tool body. Confirm the Weldon Flat shank is fully seated and the set screw is torqued per the machine tool manufacturer specification before running. Verify through-coolant passages are clear and coolant supply is active before initiating the drilling cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 1.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 1.098 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 5.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth Range\u003c\/strong\u003e: 4.5 to 6.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 6.99 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DCN A-5D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Styles\u003c\/strong\u003e: FCP, HCP-IQ, ICK, ICM, ICP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SumoCham\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Holemaking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3203521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51961967018290,"sku":"3203521","price":973.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9570511a4b50148888eaf7de74d1084f.jpg?v=1789947389","url":"https:\/\/voomisupply.com\/products\/iscar-3203521-replaceable-tip-drill-weldon-flat-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
