Designed as part of OSG's Series 3710 Exocarb WXL lineup, this single-end tool features a 0.40 mm cutting diameter and a 0.80 mm length of cut, making it well suited for fine detail work and micro-milling operations. The 2-flute, right-hand spiral geometry combined with a 30-degree helix angle promotes efficient chip evacuation and stable cutting action. A proprietary WXL PVD coating applied over an ultra-fine micrograin carbide substrate delivers hardness, heat resistance, and extended tool life across a wide range of workpiece materials. Machinists and tool-and-die professionals working in precision CNC environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use in steel, stainless steel, cast iron, and hard materials as primary workpiece materials, and is also capable in non-ferrous metals and superalloys including titanium as secondary materials. With a 4.00 mm straight-cylindrical shank diameter and a 40.00 mm overall length, it mounts directly into standard collet chucks or tool holders compatible with 4 mm shank tooling. The Series 3710 platform is designed specifically with rigidity and geometry optimized for hard milling and finishing passes where dimensional accuracy and surface finish are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.40 mm ball nose cutting diameter with a 0.20 mm nose radius for fine contour and detail milling\u003c\/li\u003e\n\u003cli\u003eWXL PVD coating over ultra-fine micrograin solid carbide substrate for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e2-flute, right-hand spiral flute geometry with 30-degree medium helix for balanced chip flow\u003c\/li\u003e\n\u003cli\u003eRated for roughing and finishing operations across steel, stainless steel, cast iron, hard materials, non-ferrous metals, and superalloys\u003c\/li\u003e\n\u003cli\u003e4.00 mm straight-cylindrical shank with h6 shank diameter tolerance for precise tool holder fitment\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of plus 0.005 mm \/ minus 0.005 mm for tight dimensional control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 4.00 mm straight-cylindrical shank.

Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the tool holder. Use a properly sized collet or tool holder rated for 4 mm shank tooling and verify runout is within acceptable limits before beginning a cut. Do not exceed the rated length of cut of 0.80 mm to avoid deflection or tool breakage on this micro-diameter end mill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 40.00 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.005 \/ -0.005 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Ultra Fine Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXL (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3710\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3105040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51755616698674,"sku":"3105040","price":92.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ad7c4aab639a94404d1e9900c7b7cd7.jpg?v=1788956986","url":"https:\/\/voomisupply.com\/products\/osg-3105040-ball-end-mill-0-40mm-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
