This single-end, 4-flute tool measures 0.1575 inches (4 mm) in cutting diameter with a length of cut of 0.9843 inches (25 mm) and an overall length of 2.9528 inches (75 mm). The 4 mm shank diameter keeps the tool compatible with standard collet systems. An AlTiN coating provides thermal resistance and extended tool life when cutting hard and exotic materials. The 38-degree helix angle promotes efficient chip evacuation and reduces cutting forces during finishing passes. Micrograin carbide construction delivers rigidity and edge sharpness required for tight-tolerance work.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for finishing cuts in materials classified under ISO workpiece material codes H, K, M, P, and S — covering hardened steels, cast irons, stainless steels, general steels, and superalloys. Its long-series designation provides additional reach for applications requiring deeper cavity work or extended projection from the holder. The variable index design reduces harmonic chatter during operation, making it well suited for high-speed machining centers and CNC milling applications where surface finish is critical. Installed by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating for high-temperature resistance and extended tool life in hard and exotic materials\u003c\/li\u003e\n\u003cli\u003e4-flute, single-end ball nose geometry optimized for finishing operations\u003c\/li\u003e\n\u003cli\u003e38-degree high helix angle promotes effective chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and sharp, durable cutting edges\u003c\/li\u003e\n\u003cli\u003eLong-series length type provides additional reach for deeper cavity and mold work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe SGS 70529 belongs to the Series 7MB product family and is suitable for use in standard 4 mm collet or shrink-fit toolholders on CNC milling machines.

Ensure the spindle and machine are fully de-energized and at a complete stop before changing tooling. Verify shank runout within the collet or holder before commencing cuts, as excessive runout will accelerate edge wear on small-diameter carbide tools. Follow shop-specific feeds, speeds, and depth-of-cut parameters appropriate for the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (mm)\u003c\/strong\u003e: 4.00 mm\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9528 inches (75.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\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\u003eVariable Helix\u003c\/strong\u003e: No\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.050 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: 0.000 to -0.008 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary 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\u003eSeries\u003c\/strong\u003e: 7MB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 70529\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732905623858,"sku":"70529","price":74.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a27f8645d4cfb4489d15ba10f96e52e3.jpg?v=1788748570","url":"https:\/\/voomisupply.com\/products\/sgs-70529-ball-end-mill-4-flute-0-1575-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
