Built from micrograin solid carbide, it carries a CVD diamond coating that delivers the wear resistance needed to cut abrasive composite fibers without rapid edge degradation. The tool measures 0.5 inches in diameter with a 1-inch length of cut and a 3-inch overall length. Its 4-flute, 30-degree right-hand spiral geometry promotes chip evacuation while maintaining a smooth cutting action. CNC machinists and toolroom operators in aerospace, automotive composites, and advanced manufacturing install this tool in machining centers and CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThe 17004994 belongs to SECO Series DIA430, a line engineered specifically for composite and CFRP machining. It is centercutting, allowing plunge entry, and features a straight 0.5-inch shank for standard collet or end mill holder compatibility. The right-hand cut and right-hand flute configuration suits conventional and climb milling in horizontal or vertical CNC machining centers. No extended reach or coolant-through capability is present, making it best suited for dry or mist-assisted cutting strategies typical in composite work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD diamond coating optimized for abrasive CFRP and composite materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge integrity\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with straight shank for standard toolholding\u003c\/li\u003e\n  \u003cli\u003eTight mill diameter tolerance of -0.0010 \/ +0.0010 inches for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill replacement for CNC machining centers and milling machines using standard 0.5-inch straight-shank toolholders or collets.

Power down and lock out the machining center spindle before changing tooling. Seat the straight shank fully into the collet or end mill holder and torque the retention nut to the toolholder manufacturer's specification. Verify runout does not exceed the rated TIR maximum of 0.0005 inches before beginning a cut; excessive runout accelerates edge wear on diamond-coated tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD Diamond\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: 17004994\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558275907890,"sku":"17004994","price":447.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cff8b782a916395270502322a9788f29_ea74badd-fd7f-49f5-828a-8f4a54eb28e8.jpg?v=1786408198","url":"https:\/\/voomisupply.com\/products\/seco-17004994-square-end-mill-0-5-in-4-flute-cvd-diamond-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
