Built on the Series 7B platform, this single-end tool features a 0.125 inch mill diameter and a 1 inch length of cut, with an extra-long 3 inch overall length that provides extended reach into deep cavities and pockets. The four-flute, right-hand spiral design runs at a 45-degree high helix angle, promoting efficient chip evacuation and smooth surface finishes. An AlTiN coating improves heat resistance and tool life in abrasive and high-temperature cutting environments. The micrograin carbide substrate delivers the edge toughness needed for finishing passes on difficult materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision finishing operations in tool rooms, production shops, and aerospace or medical component machining environments. The variable index geometry reduces chatter and harmonic vibration during cut, making it effective for tight-tolerance work in ferrous and non-ferrous materials. It is installed and operated by machinists and CNC programmers using standard ER or similar collet toolholding systems. Primary workpiece material codes H, K, M, P, and S indicate suitability across a range of steels, stainless alloys, titanium, cast iron, and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.125 inch mill diameter with a 1 inch length of cut for detail and cavity work\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral configuration for efficient chip removal during finishing\u003c\/li\u003e\n  \u003cli\u003e45-degree high helix angle reduces cutting forces and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances heat resistance and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides edge strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter for improved dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eExtra-long 3 inch OAL allows access to deep features without tool extension add-ons\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard 0.125 inch collet toolholding systems.

Intended for use in CNC milling machines and machining centers running appropriate speeds and feeds for solid carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator using a properly sized collet or end mill holder. Ensure the shank is fully seated and the collet is torqued per the toolholder manufacturer specifications before spindle engagement. Verify runout at the tool tip prior to cutting to protect the 0.125 inch diameter from deflection-related breakage. Do not use this tool in worn or out-of-spec toolholders, as shank fit directly affects edge life and dimensional output.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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 -0.00032 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 7B\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\u003eCompatible Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 70442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51739909488946,"sku":"70442","price":71.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a27f8645d4cfb4489d15ba10f96e52e3_c4d58989-ba7b-49ce-9c97-ac00d97fc58b.jpg?v=1788820281","url":"https:\/\/voomisupply.com\/products\/sgs-70442-ball-end-mill-0-125-in-4-flute-altin-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
