Part of the DIA430 series, it features a CVD diamond coating applied to a micrograin carbide substrate, producing exceptional hardness and wear resistance suited for carbon fiber reinforced polymer (CFRP) cutting. The tool measures 0.125 inches in diameter with a 0.5 inch length of cut and a 1.5 inch overall length. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation. Right-hand cut and right-hand flute geometry is standard. The centercutting design allows plunge entry into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for professional machining applications where CFRP, composites, and other abrasive non-metallic materials are being processed. The CVD diamond finish extends tool life significantly compared to uncoated or PVD-coated carbide tooling in these materials. The 1\/8 inch straight shank fits standard collet chucks used on CNC machining centers, high-speed spindles, and precision manual mills. The regular-length profile keeps the tool rigid during high-feed passes in shallow-to-moderate depth cuts. It is sold and packaged as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD diamond coating for maximum abrasion resistance in CFRP and composite materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge stability at small diameters\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix angle for controlled chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight 1\/8 inch shank fits ER and DA collet systems without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling solution for CNC machining centers and high-speed spindles accepting 1\/8 inch straight-shank end mills.

Power down the spindle and engage the machine lock before changing tooling. Seat the shank fully in the collet and torque the collet nut to the chuck manufacturer's specification using the appropriate spanner wrench. Verify runout does not exceed the TIR maximum of 0.0005 inches before beginning production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inch)\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD Diamond\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\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\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\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: 17004988\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560836923698,"sku":"17004988","price":140.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cff8b782a916395270502322a9788f29_074a81eb-6fb1-42ab-80a1-b25ce4ab03a8.jpg?v=1786458470","url":"https:\/\/voomisupply.com\/products\/seco-17004988-square-end-mill-1-8-in-4-flute-cvd-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
