It accepts a range of interchangeable drill tip inserts, allowing the body to be reused while only the cutting tip is replaced. The drill covers a diameter range of 0.256 to 0.271 inches with a maximum drill depth of 1.3 inches and a 5xD depth-to-diameter ratio. A 1\/2-inch straight-cylindrical shank provides secure clamping in standard drill chucks or tool holders. Through-coolant capability supports chip evacuation and heat management during deep hole operations. This toolholder is installed and serviced by machinists and CNC operators in production or job shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 3203281 is suited for holemaking operations on machining centers and CNC lathes where repeatable, accurate hole diameter is required. The replaceable-tip design reduces tooling cost by eliminating full drill replacement when the cutting edge wears. It is applicable in general metalworking, automotive, aerospace, and die-mold production environments where tight diameter tolerances and consistent drill depth are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDiameter range of 0.256 to 0.271 inches accommodates insert tip variation within SumoCham series\u003c\/li\u003e\n  \u003cli\u003e5xD drill depth-to-diameter ratio with 1.3 inches maximum drill depth\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant channels support chip evacuation and tool life in deep hole cutting\u003c\/li\u003e\n  \u003cli\u003eCompatible with FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M insert styles, seat size 6.5\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight-cylindrical shank fits standard toolholders without special adapters\u003c\/li\u003e\n  \u003cli\u003eISO 13399 compliant toolholder data for integration with CAM and tool management software\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with FCP, ICK, ICK-2M, ICM, ICN, ICP, and iCP-2M replaceable drill tip inserts at insert seat size 6.5.

Ensure the insert seat is clean and free of chips before seating a new tip, as contamination can cause runout and affect hole accuracy. Torque the insert securing screw only with the correct ISCAR wrench specified for this seat size. Verify shank clamping is within the toolholder manufacturer minimum engagement length before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SumoCham\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: DCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 0.256 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 0.271 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.61 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 6.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Styles\u003c\/strong\u003e: FCP, ICK, ICK-2M, ICM, ICN, ICP, iCP-2M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 0.637 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3203281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755808031026,"sku":"3203281","price":334.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5826fd996f2940c5f8906dbdaf81d895.jpg?v=1788959938","url":"https:\/\/voomisupply.com\/products\/iscar-3203281-replaceable-tip-drill-0-256-0-271-in","provider":"Voomi Supply","version":"1.0","type":"link"}
