With a 1\/2 inch cutting diameter and a 0.1 inch corner radius, it produces smooth, radiused edges while reducing stress concentrations at corners. The 5-flute variable-pitch geometry paired with a 38-degree helix angle promotes chip evacuation and surface finish quality. AlTiN coating adds thermal hardness and oxidation resistance, making this tool well-suited for dry or high-speed cutting environments. Machinists and CNC operators install this end mill for finishing and semi-finishing passes where corner integrity matters.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers handling profiling, slotting, and contouring operations. The 1-1\/4 inch length of cut accommodates moderate-depth passes, while the 3 inch overall length and 1\/2 inch shank diameter fit standard ER and side-lock toolholders. The centercutting design allows plunge entry directly into the workpiece. Variable pitch reduces harmonic chatter, which is especially useful on long-run production cycles or when machining harder alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1 inch corner radius reduces stress risers and improves part longevity\u003c\/li\u003e\n\u003cli\u003e5-flute variable-pitch design minimizes chatter and supports higher feed rates\u003c\/li\u003e\n\u003cli\u003e38-degree right-hand helix promotes chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal resistance for dry and high-speed cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 1\/2 inch shank end mill holders used in CNC machining centers and manual mills accepting standard straight-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set screw torque meets the toolholder manufacturer's specification. Inspect the cutting edges and coating for damage before each use; do not run a chipped or worn tool at rated parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: Variable\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5680944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731965903154,"sku":"5680944","price":280.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/126732d9fe51b2dca889234f96d391c9.jpg?v=1788737360","url":"https:\/\/voomisupply.com\/products\/iscar-5680944-corner-radius-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
