Part of the JS553 series, it features a 0.0787 inch (2.00 mm) mill diameter, a 0.1969 inch (5.00 mm) length of cut, and a 0.2362 inch (6.00 mm) shank diameter. The three-flute, right-hand spiral geometry runs at a 48-degree helix angle, promoting efficient chip evacuation and smooth cutting action. The SIRON-A coating provides enhanced wear resistance and thermal protection, extending tool life across a wide range of workpiece materials. This is a single-end, center-cutting tool suited for slotting, profiling, and peripheral milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use on CNC machining centers and manual mills where tight tolerances and surface finish quality are required. Its micrograin carbide construction and SIRON-A coating make it well-suited for production work in steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. Typical users include machinists, tool and die makers, and CNC programmers working in job shops or manufacturing environments that require a reliable small-diameter end mill for intricate features and finish passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0787 inch (2.00 mm) mill diameter with 0.1969 inch (5.00 mm) length of cut for precise small-feature machining\u003c\/li\u003e\n\u003cli\u003eThree-flute right-hand spiral design with 48-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSIRON-A coating for improved wear resistance and extended tool life in difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge sharpness retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, cast iron, high-temp alloys, aluminum, and hardened materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with steel (P), stainless steel (M), cast iron (K), high-temperature alloys (S), aluminum and non-ferrous metals (N), and hardened materials (H) as designated by ISO workpiece material codes.

Ensure the shank is properly seated and torqued in a collet or end mill holder rated for the 0.2362 inch shank diameter before operation. Verify spindle speed, feed rate, and depth of cut are set according to the material being machined and toolholder specifications before starting the cut. Do not exceed the tool's rated length-of-cut depth in a single pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0787 inches (2.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1969 inches (5.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 48 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: SIRON-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JS553\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.25 inches L x 0.5 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.21 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: 02733903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563348558130,"sku":"02733903","price":86.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2d3a182a581a94da8617feacf7d7ddf_a26961cc-9e0e-48e7-a99c-00747c23194e.jpg?v=1786496169","url":"https:\/\/voomisupply.com\/products\/seco-02733903-square-end-mill-0-0787-in-3-flute-carbide-js553","provider":"Voomi Supply","version":"1.0","type":"link"}
