With a 0.25-inch mill diameter and a 0.75-inch length of cut, it delivers precise material removal on hardened and abrasive workpiece materials. The 5-flute geometry paired with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes at elevated feed rates. A diamond coating provides exceptional hardness and wear resistance, extending tool life in non-ferrous, composite, and abrasive material applications. Licensed machinists and CNC operators working in aerospace, mold-and-die, and precision machining shops are the primary end users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for edging, slotting, and peripheral milling operations where tight tolerances and surface finish quality are critical. It is part of the CoroMill Plura solid carbide end mill series, which is engineered for high-performance cutting in non-ferrous metals, carbon fiber reinforced polymers (CFRP), graphite, and other abrasive materials. The right-hand cutting and right-hand flute direction make it compatible with standard CNC machining center spindles. The 0.25-inch shank diameter fits standard ER and shrink-fit collet systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25-inch mill diameter with 0.75-inch length of cut for precise edging operations\u003c\/li\u003e\n\u003cli\u003e5-flute spiral geometry with 40-degree helix angle for high feed rates and smooth chip flow\u003c\/li\u003e\n\u003cli\u003eDiamond coating for maximum wear resistance in abrasive and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability under load\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable  -  suitable for plunge entry where required\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 2.5-inch overall length and 0.25-inch shank diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the CoroMill Plura solid carbide end mill series, designed for edging applications in abrasive and non-ferrous materials.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention system to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear on diamond-coated tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\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 (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eEnd Type\u003c\/strong\u003e: Single End\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: Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: O12M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill Plura\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7254439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51739395096882,"sku":"7254439","price":339.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c278bfe533d5f6e81c2a7d4861510e5.jpg?v=1788814036","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7254439-square-end-mill-1-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
