Built from micrograin solid carbide, it delivers the rigidity and edge retention required for hardened steels, cast irons, stainless steels, carbon steels, and superalloys. The 0.25-inch cutting diameter pairs with a 0.75-inch length of cut and a 2.5-inch overall length, keeping deflection low in typical milling setups. An AlTiN coating provides thermal resistance and oxidation protection at elevated cutting speeds, extending tool life in dry or near-dry cutting conditions.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish milling of complex contoured surfaces, pockets, and profiled features on CNC machining centers. The variable helix and variable index geometry reduce harmonic chatter, making it effective in both light and moderate material removal passes. It is sized and configured for production environments and toolrooms where consistent surface finish and dimensional accuracy are required. Primary workpiece material classifications H, K, M, P, and S indicate suitability across hardened steels, cast iron, stainless, carbon steel, and superalloy workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for thermal and oxidation resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry to suppress chatter\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut and right-hand spiral configuration\u003c\/li\u003e\n  \u003cli\u003eBall nose profile for contour and 3D surface finishing\u003c\/li\u003e\n  \u003cli\u003eSeries Z1B design optimized for finishing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 0.25-inch straight shank.

Verify runout at the spindle and toolholder before cutting to protect the cutting edge. Confirm tool projection and reach requirements match the workpiece geometry before starting the program. Follow the cutting tool manufacturer's recommended speeds and feeds for the specific workpiece material and machine setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 to -0.00035 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Z1B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51728819814706,"sku":"36590","price":60.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5f513f10a49f75f93aa052126aac10f.jpg?v=1788696376","url":"https:\/\/voomisupply.com\/products\/sgs-36590-ball-end-mill-0-25-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
