With a 0.25-inch cutter diameter and a 0.75-inch length of cut, this single-end tool delivers consistent performance in tight-tolerance applications. Eight flutes provide a high flute count for improved surface finish and material removal in finish-pass operations. The amorphous diamond coating increases surface hardness and reduces friction, making this end mill well-suited for machining abrasive non-ferrous materials, composites, and graphite. Right-hand cutting direction with a 10-degree helix angle supports chip flow and edge stability during cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where fine surface finish and dimensional accuracy are required. The 0.25-inch shank diameter fits standard ER collets and end mill holders commonly found in production and toolroom environments. With a 2.5-inch overall length, the tool maintains rigidity while providing adequate reach for most shallow-to-mid-depth milling operations. Machinists working with abrasive plastics, carbon fiber reinforced polymers, green ceramics, or high-silicon aluminum alloys will find the amorphous diamond coating particularly effective at extending tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25-inch cutter diameter with 0.75-inch length of cut for precise shallow milling\u003c\/li\u003e\n  \u003cli\u003e8-flute geometry for improved surface finish and reduced chip load per flute\u003c\/li\u003e\n  \u003cli\u003eAmorphous diamond coating for high hardness and abrasion resistance in non-ferrous and composite materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003e10-degree helix angle supports chip evacuation and edge stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNC machining centers and manual mills accepting a 0.25-inch shank diameter via ER collet or end mill holder.

Ensure the spindle is fully powered down and at rest before changing tooling. Secure the shank in a clean, properly sized collet or end mill holder to the appropriate clamping torque per the holder manufacturer's specifications. Inspect the cutting edges and coating for chips or damage before each use, and do not use this tool on ferrous metals, as diamond coatings react adversely with iron-based materials at cutting temperatures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter 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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Amorphous Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 944816-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51748700520754,"sku":"944816-C4","price":154.41,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fd8ec27430cd9e33be066ad5b1d9dae_4fcecf26-d247-4b16-aeed-813befab6185.jpg?v=1788896959","url":"https:\/\/voomisupply.com\/products\/harvey-tool-944816-c4-square-end-mill-1-4-in-8-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
