With a 0.25 inch mill diameter and a 0.75 inch length of cut, this single-end tool delivers precise, repeatable results in demanding machining applications. The CVD diamond coating provides exceptional hardness and wear resistance, making it well-suited for cutting graphite, carbon fiber, ceramics, and other abrasive non-ferrous materials. The 30-degree helix angle promotes efficient chip evacuation, reducing heat buildup and tool wear. This end mill is installed and operated by machinists and CNC tooling professionals working in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC milling operations where abrasive or composite workpiece materials require a coating harder than standard TiN or TiAlN options. It fits standard 0.25 inch collets and tool holders. With a 2.5 inch overall length and 0.25 inch shank diameter, it is suited for benchtop and production CNC mills handling moderate-depth slotting, profiling, and contouring passes in tight-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD diamond coating for superior wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cutting and flute direction for standard CNC milling setups\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 0.75 inch length of cut and 2.5 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.25 inch collet-style CNC tool holders.

Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Secure the shank to the full recommended engagement depth in the collet or tool holder to minimize runout and prevent pullout under load. Confirm correct spindle direction matches the right-hand cutting geometry of this end mill before initiating any cut.\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\u003eShank 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: CVD Diamond\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\u003ePackage Dimensions\u003c\/strong\u003e: 2.6 x 0.51 x 0.51 inches\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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 799816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51783022182706,"sku":"799816","price":229.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a61dcf0d400a6a5af260b4fbc62723e0_6c2807e9-054f-4829-8db4-cc7812bee368.jpg?v=1789184449","url":"https:\/\/voomisupply.com\/products\/harvey-tool-799816-square-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
