It features a 0.25 inch cutting diameter with a 1.5 inch length of cut, a 0.25 inch shank diameter, and a 4 inch overall length. The two-flute geometry paired with a 30-degree helix angle promotes efficient chip evacuation, making it well suited for slotting, profiling, and pocketing in a range of ferrous and non-ferrous materials. The AlTiN (aluminum titanium nitride) coating extends tool life at elevated cutting temperatures. This end mill is single-end, center-cutting, and right-hand cut, and is installed by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThe HERTEL 750592 is used in vertical and horizontal milling machines as well as CNC machining centers. Its center-cutting design allows plunge entry directly into the workpiece, adding versatility to complex part programs. The 0.25 inch diameter and two-flute configuration are commonly applied to fine-detail features, narrow slots, and contour passes in steel, stainless steel, cast iron, and hardened alloys. The AlTiN finish makes it particularly effective in dry or semi-dry cutting conditions where heat buildup is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25 inch cutting diameter with 1.5 inch length of cut for deep-feature access\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance over high-speed tool steels\u003c\/li\u003e\n\u003cli\u003eAlTiN coating resists oxidation and thermal wear in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design permits direct plunge milling without pre-drilled entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, single-end configuration compatible with standard ER and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement end mill for standard 0.25 inch end mill holders and collet chucks used in CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using an ER collet chuck, side-lock holder, or shrink-fit toolholder rated for the shank diameter. Ensure the machine spindle is fully stopped and locked before changing tooling. Confirm runout with a dial indicator after seating the tool to avoid premature edge wear. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 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\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750592\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728682680626,"sku":"750592","price":60.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26c3e4108295aebfd2675ed78a800f9b.jpg?v=1788694945","url":"https:\/\/voomisupply.com\/products\/hertel-750592-carbide-square-end-mill-0-25in-2-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
