Built from solid carbide, it delivers the rigidity and wear resistance required for cutting ferrous and non-ferrous materials at elevated speeds. The 0.25 inch diameter cutting head and 0.75 inch length of cut make it well suited for tight-radius passes and shallow-to-medium depth pocketing. A titanium nitride (TiN) coating reduces friction and extends tool life compared to uncoated carbide. Right-hand cutting and right-hand flute geometry are standard for conventional CNC and manual milling setups.\u003c\/p\u003e\u003cp\u003eThis end mill fits residential machine shops, production floors, and toolrooms where small-diameter profiling work is routine. It is appropriate for CNC machining centers and manual knee mills using a 0.25 inch collet or end mill holder. The 2.5 inch overall length suits most standard tool holders without requiring extended-reach adapters. Machinists working aluminum, mild steel, alloy steel, and similar materials will find the TiN coating provides a useful performance advantage over bare carbide in moderate-to-high feed-rate operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and extended wear life\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and improves tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e2-flute geometry provides efficient chip evacuation in slotting and profiling cuts\u003c\/li\u003e\n\u003cli\u003eBall end profile enables 3D contouring, radial profiling, and blend passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard CNC and manual mill compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 0.25 inch shank for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 0.25 inch shank end mill holder or collet.

Before changing tooling, confirm the spindle is fully stopped and the machine is in a safe, powered-down state per shop lockout\/tagout procedures. Seat the shank fully into the collet or holder and torque the retention hardware to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout on small-diameter carbide tools increases the risk of breakage.\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\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\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 0.15 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: E6249016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741653238066,"sku":"E6249016","price":44.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a27d6e4e3b7d04621f1d5fc1ec77eb77.jpg?v=1788832746","url":"https:\/\/voomisupply.com\/products\/hertel-e6249016-ball-end-mill-0-25-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
