With a 1\/4 inch diameter and a 1-1\/8 inch length of cut, it handles slotting, profiling, and peripheral milling in a single-end configuration. The micrograin carbide substrate provides rigidity and edge retention, while the Titanium Nitride (TiN) coating reduces friction and extends tool life. A 30-degree helix angle and four right-hand spiral flutes support efficient chip evacuation. Overall length is 3 inches with a 1\/4 inch shank diameter. This tool is installed by machinists and CNC operators working in job shops, tool rooms, and production machining cells.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous metals in both manual and CNC milling machines. Its centercutting geometry allows plunge entry as well as conventional milling passes. The 1\/4 inch shank is compatible with standard collet chucks, end mill holders, and shrink-fit tooling systems commonly found in vertical machining centers and knee mills. It is a single-end tool, meaning the working end is on one side only.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life in ferrous applications\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for effective chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports both plunge and peripheral milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1\/4 inch straight shank\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems used in CNC vertical machining centers and conventional knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the toolholder to the recommended gauge depth before tightening. Ensure the spindle is fully stopped and the machine control is in a safe state before changing tooling. Follow the machine manufacturer and toolholder manufacturer torque specifications for collet nut or set screw engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/8 inches (1.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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 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\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750273\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734979871026,"sku":"750273","price":50.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6bf0d4bfc4ec24f8d08aed7514e7f76.jpg?v=1788768828","url":"https:\/\/voomisupply.com\/products\/hertel-750273-square-end-mill-1-4-in-4-flute-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
