It features a 0.5-inch diameter, a 1.5-inch length of cut, and a 6-inch overall length, making it well suited for extended-reach applications where standard-length tooling cannot access the workzone. The micrograin carbide substrate supports the TiCN coating, which improves surface hardness and wear resistance over uncoated tooling. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. This is a centercutting tool, allowing plunge cuts in addition to peripheral and slot milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual milling machines for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The extra-long length classification makes it a practical choice when clearing deep pockets, tall workpiece features, or fixtures that obstruct shorter tooling. The right-hand cut and right-hand flute configuration is standard for conventional spindle setups. Machinists, tool-and-die makers, and CNC operators in job shops and production environments are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN finish increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6-inch OAL provides extended reach for deep-feature milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 0.5-inch collet chucks, end mill holders, and shrink-fit holders accepting a 0.5-inch shank diameter in CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and power is off before loading or changing tooling. Use a properly sized collet or end mill holder torqued according to the toolholder manufacturer's specifications. Verify runout with a dial indicator after seating the tool before beginning a cut, particularly given the extended overall length of this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 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: 750300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732468957490,"sku":"750300","price":175.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a85bc462f4ebfe4179f7925a852d42a7.jpg?v=1788743146","url":"https:\/\/voomisupply.com\/products\/hertel-750300-square-end-mill-0-5in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
