It features a 0.5 inch diameter, a 0.0300 inch corner radius, and six flutes arranged in a right-hand spiral with a 45-degree high helix angle. The AlTiN PVD coating provides thermal resistance and extended tool life under aggressive cutting conditions. With a short flute length of 1.125 inches and a 4 inch overall length, this tool is sized for controlled material removal in tight setups. It is centercutting and capable of both roughing and finishing passes in a single tool. Licensed machinists and CNC operators install this end mill in compatible toolholders for high-performance milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining steel and hard materials in CNC milling centers and manual mills. The MZ645R series is built for shops running close-pitch, high-helix applications where surface finish and dimensional accuracy are critical. The straight-cylindrical shank accepts standard collet and shrink-fit toolholders. It performs well in applications requiring consistent corner radii on profiled workpieces, slots, and pockets in ferrous and hardened materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300 inch corner radius with tolerance of +0.00100 to -0.00100 inches for precise edge geometry\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for heat resistance and extended tool life in steel and hard material cuts\u003c\/li\u003e\n\u003cli\u003eSix-flute, close-pitch spiral design supports both roughing and finishing material removal\u003c\/li\u003e\n\u003cli\u003e45-degree high helix angle improves chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability under high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard collet, hydraulic, and shrink-fit toolholders accepting a 0.5 inch straight-cylindrical shank.

Ensure the toolholder bore and shank mating surfaces are clean and free of debris before seating the end mill. Power down and lock out the spindle before inserting or removing the tool. Follow machine manufacturer guidelines and applicable shop safety standards when setting tool length offsets and cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 to +0.0600 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel and Hard Material\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: MZ645R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17004778\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559602290994,"sku":"17004778","price":446.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f03fefb2a3219af0f6b038efeb88d51.jpg?v=1786436226","url":"https:\/\/voomisupply.com\/products\/seco-17004778-corner-radius-end-mill-0-5in-6-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
