It features a 0.25-inch cutting diameter, a 1.5-inch length of cut, and a 4-inch overall length with a 0.25-inch shank diameter. The four-flute geometry with a 30-degree helix angle provides an efficient balance of chip evacuation and surface finish. An amorphous diamond coating is applied to the flute and cutting edge surfaces to extend tool life in abrasive and high-wear applications. This end mill is centercutting, allowing plunge entry. It is sold as a single unit and is a direct-order replacement-grade tool intended for machining professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling, slotting, profiling, and light pocketing operations on CNC machining centers and manual mills. The right-hand cut and right-hand flute direction follow standard toolholder conventions. Its compact 0.25-inch diameter makes it well suited for detailed features, tight corners, and fine contour work on mold, die, and precision component applications. The amorphous diamond coating provides added performance when cutting composites, graphite, and other abrasive workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAmorphous diamond coating extends tool life in abrasive and composite materials\u003c\/li\u003e\n\u003cli\u003eFour-flute, 30-degree helix geometry balances chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC toolholders\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits standard collets and shrink-fit holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill replacement compatible with standard 0.25-inch collet chucks, ER collets, and shrink-fit toolholders used on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before changing tooling. Verify collet runout is within acceptable limits before securing the shank, as excessive runout accelerates edge wear. Consult the machine manufacturer guidelines and applicable shop safety standards when setting speeds and feeds for the workpiece material.\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: 1.5 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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\/Finish\u003c\/strong\u003e: Amorphous Diamond\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\u003eFlute 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\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\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728534274354,"sku":"77016","price":95.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50214e3950c3ec2771b92c48a63192ff_9c2fa3ed-b33e-45e2-8ef3-fa325a7d1636.jpg?v=1788692873","url":"https:\/\/voomisupply.com\/products\/harvey-tool-77016-square-end-mill-0-25in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
