Part of the DIAL430 series, it features a CVD diamond coating that delivers exceptional abrasion resistance when cutting highly abrasive composite materials. The cutter measures 0.25 inches in diameter with a 1.25-inch length of cut and a 3-inch overall length. Its 4-flute, spiral geometry with a 30-degree helix angle promotes chip evacuation while maintaining surface finish quality. The micrograin carbide substrate provides the rigidity and edge retention required for high-speed composite machining. This tool is sold as a single-end design.\u003c\/p\u003e\u003cp\u003eThis end mill is primarily intended for machining CFRP and other abrasive composite materials in aerospace, automotive, and advanced manufacturing environments. The CVD diamond coating makes it well suited for applications where uncoated or conventionally coated carbide tools wear prematurely. The centercutting design allows plunge entry as well as peripheral milling operations. A right-hand cut with right-hand flute direction and straight shank make it compatible with standard CNC machining center and router toolholders. It is a long-length classification tool, offering extended reach into workpiece features without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD diamond coating optimized for abrasion resistance in CFRP and composite materials\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables plunge milling and slot entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge retention and dimensional stability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute, straight shank for standard toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of -0.0010\/+0.0010 inches and TIR maximum of 0.0005 inches for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC machining centers and routers requiring a 0.25-inch straight-shank square end mill for CFRP and composite material applications.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Use a collet or end mill holder rated for the 0.25-inch shank diameter and torque to the toolholder manufacturer's specification. Inspect the cutting edges and coating condition before each use, as CVD diamond coatings are brittle and can chip if the tool is dropped or mishandled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: CFRP Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0010\/+0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600\/-0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DIAL430\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17005008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557799821618,"sku":"17005008","price":285.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0e6cff87464a295035620679820cbff.jpg?v=1786395586","url":"https:\/\/voomisupply.com\/products\/seco-17005008-square-end-mill-1-4-in-4-flute-cvd-diamond-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
