Built on the JS553 series platform, it features a 1\/8 inch (0.1252 inch decimal) mill diameter, a 1\/4 inch length of cut, and a 45-degree chamfer angle with a 0.0016 inch chamfer width. The 48-degree high-helix geometry promotes efficient chip evacuation and surface finish quality. The SIRON-A PVD coating — an AlCrN-based treatment — provides thermal resistance and wear protection suited for dry or near-dry cutting conditions. This is a single-end, right-hand cut, right-hand flute tool with centercutting capability, making it suitable for both entry cuts and lateral passes.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material groups P, M, K, N, and S. Its short length type and straight-cylindrical shank make it a fit for standard collet toolholding systems on CNC machining centers and manual mills. Documented applications include shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging and recessing operations. The micrograin carbide substrate supports the high cutting speeds and feeds these operations demand.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSIRON-A PVD (AlCrN) coating for thermal wear resistance on ferrous and superalloy workpieces\u003c\/li\u003e\n\u003cli\u003e48-degree high-helix angle promotes aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunging and ramp-down entry\u003c\/li\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0016 inch chamfer width for edge-break and chamfering operations\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity at small diameters\u003c\/li\u003e\n\u003cli\u003eNormal pitch, no chipbreaker, no coolant-through — optimized for standard toolholding setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8 inch collet or end mill holders on CNC machining centers and manual mills.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the straight-cylindrical shank fully into the collet or holder before tightening to manufacturer torque specifications for the toolholder in use. Verify runout with a dial indicator before cutting — maximum TIR for this tool is 0.0004 inch.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1252 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1252 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0016 inch\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\u003eHelix Style\u003c\/strong\u003e: High\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, Centercutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: SIRON-A (AlCrN, PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: e7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JS553\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 02712684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559741522226,"sku":"02712684","price":90.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b5a583c770789f87851375a3d31f499.jpg?v=1786439708","url":"https:\/\/voomisupply.com\/products\/seco-02712684-corner-chamfer-end-mill-1-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
