With a 0.25-inch mill diameter, a 1.5-inch length of cut, and a 4.0-inch overall length, this extra-long tool provides extended reach for deep-cavity and contoured-surface work. The 45-degree high helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN coating delivers thermal resistance and hardness, making this end mill well suited for aggressive cuts in hard or abrasive workpiece materials. It is a single-end, right-hand cut, right-hand flute tool manufactured from micrograin carbide stock.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for finishing passes on a range of workpiece material categories including hardened steels, cast irons, stainless steels, carbon steels, and high-temperature alloys, corresponding to material codes H, K, M, P, and S. The extra-long configuration and 0.25-inch shank diameter make it appropriate for vertical machining centers, CNC mills, and similar setups where reach into deep pockets, molds, or complex 3D profiles is required. It is used by machinists and tool-and-die professionals in job shops, aerospace component production, and precision mold work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal protection and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e45-degree high helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eVariable index geometry minimizes chatter during finishing passes\u003c\/li\u003e\n\u003cli\u003eExtra-long 4.0-inch overall length with 1.5-inch length of cut for deep-reach applications\u003c\/li\u003e\n\u003cli\u003eBall end profile suited for 3D contour finishing and radius floor work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4-inch collet or end mill holders on CNC vertical machining centers and manual mills.

Ensure the collet or end mill holder is clean and free of debris before seating the 0.25-inch shank. Confirm the spindle is fully stopped and the machine is in a safe state before changing tooling. Observe the mill diameter tolerance of +0.000 to -0.002 inches and shank tolerance of +0.00000 to -0.00035 inches when qualifying the tool for precision setups.\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\u003eOverall Length\u003c\/strong\u003e: 4.0 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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 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\u003eSeries\u003c\/strong\u003e: 7B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Materials\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.5 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743377424690,"sku":"70448","price":88.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a27f8645d4cfb4489d15ba10f96e52e3_10281eba-e787-456a-a211-af5ed9e9b52b.jpg?v=1788846344","url":"https:\/\/voomisupply.com\/products\/sgs-70448-ball-end-mill-0-25-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
