Built on the DIA430 series platform, it features a CVD diamond coating that provides exceptional hardness and wear resistance, making it a direct fit for machining carbon fiber reinforced polymer (CFRP) materials. The tool measures 3\/16 inch in diameter with a 5\/8 inch length of cut and 2 inch overall length. A 4-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Centercutting capability allows plunge entry without a pilot hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for single-end milling operations in industrial and aerospace machining environments where CFRP composites are common workpiece materials. The straight shank with a 3\/16 inch diameter is compatible with standard collet systems. It is ideal for machinists and CNC operators working with abrasive composite materials that rapidly wear uncoated or PVD-coated tooling. The regular length configuration fits most vertical and horizontal CNC milling setups without requiring extended-reach holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD diamond coating for superior wear resistance in CFRP and abrasive composite materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge integrity at small diameters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration standard for CNC milling spindles\u003c\/li\u003e\n  \u003cli\u003eTight mill diameter tolerance of -0.0010\/+0.0010 inch for accurate finished dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CFRP and other abrasive composite materials as the primary workpiece.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout\/tagout state before changing tooling. Seat the straight shank fully into the collet and torque the collet nut to the tool holder specification. When machining CFRP, use appropriate dust extraction and respiratory controls per applicable shop safety requirements, as composite dust presents a health hazard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eCutting 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: DIA430\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17004989\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562530603314,"sku":"17004989","price":167.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cff8b782a916395270502322a9788f29_7c4b1c08-8e5c-45e7-afbe-95b3247d685a.jpg?v=1786478900","url":"https:\/\/voomisupply.com\/products\/seco-17004989-square-end-mill-3-16-in-4-flute-carbide-cvd","provider":"Voomi Supply","version":"1.0","type":"link"}
