It measures 5\/32 inch (0.1563 inches) in diameter with a 9\/16 inch (0.5625 inches) length of cut and a 2 inch overall length. The 3\/16 inch shank diameter provides a secure tool holder interface. Manufactured from micrograin solid carbide and finished with an AlTiN coating, this end mill handles demanding cutting conditions at elevated temperatures. The 30-degree helix angle and centercutting geometry allow both plunge and peripheral milling operations. Right-hand cut direction is standard. This tool is intended for use by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe HERTEL 750539 suits small-feature milling work including slots, pockets, and profiling cuts in ferrous and non-ferrous materials. Its micrograin carbide substrate and AlTiN finish make it suitable for dry or near-dry cutting in hardened steels, stainless, and high-temperature alloys where heat resistance is a priority. The compact 5\/32 inch diameter targets tight-tolerance features common in mold making, die work, and precision component machining. Single-end configuration means the tool is replaced rather than indexed when worn.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish extends tool life in high-temperature cutting environments\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip clearance and surface finish in small-diameter applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, single-end configuration standard for CNC mill and manual mill use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement end mill for any tool holder accepting a 3\/16 inch round shank, including collet chucks, end mill holders, and shrink-fit holders used on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Always confirm the tool holder bore matches the 3\/16 inch shank diameter before securing. De-energize and lock out the spindle drive before loading or removing tooling. Torque collet nuts to the holder manufacturer specification and verify tool runout with a dial indicator before production cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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 Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750539\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737603014962,"sku":"750539","price":40.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47182331e3106b3b30f44d894b5d8797.jpg?v=1788791219","url":"https:\/\/voomisupply.com\/products\/hertel-750539-square-end-mill-5-32-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
