With a 0.25 inch cutting diameter and a 0.5 inch length of cut, this end mill delivers accurate, repeatable results in ferrous and non-ferrous materials. The 2-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A titanium nitride (TiN) finish increases surface hardness and reduces friction at the cutting edge, extending tool life under demanding conditions. The right-hand cut, centercutting design allows both plunge and peripheral milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers, manual knee mills, and benchtop milling setups where a compact, precise cutting tool is required. The 0.25 inch shank diameter fits standard ER collets and end mill holders common in production and job-shop environments. The 2.0 inch overall length keeps the tool rigid and minimizes deflection in shallow-to-moderate depth cuts. Machinists working in aerospace, automotive, tooling, and general fabrication will find this a reliable option for finish passes and light profiling work in steel, aluminum, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction provides superior rigidity and wear resistance compared to high-speed steel\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces built-up edge in ferrous materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle with spiral flutes promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation on most mills\u003c\/li\u003e\n\u003cli\u003e2-flute design offers wider chip gullets, beneficial when milling softer metals and plastics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with standard 0.25 inch shank collet chucks and end mill holders used in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholding torque requirements and runout specifications. Always power down and lock out the spindle before changing tooling. Ensure the collet or holder bore is clean and free of chips before seating the shank to the recommended insertion depth. Verify runout with a dial indicator before beginning a cut to prevent premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 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\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 750538\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739646886194,"sku":"750538","price":44.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e6d0dedc5ab72966a5321f73c5d6561.jpg?v=1788817290","url":"https:\/\/voomisupply.com\/products\/hertel-750538-square-end-mill-0-25in-2-flute-carbide-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
