Part of OSG's Series 3790 Exocarb WXL line, this single-end tool carries a 0.50 mm (0.0197 inch) mill diameter with a 0.40 mm length of cut and a 4.00 mm straight-cylindrical shank. The WXL PVD coating provides elevated wear resistance when cutting pre-hardened and hardened steels. With a 30-degree medium helix and ultra fine micrograin carbide substrate, it balances cutting efficiency with edge integrity during both roughing and finishing passes. Licensed machinists and CNC operators in precision machining environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision milling operations on steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. The extended reach configuration, with a 2.00 mm reach length and 0.45 mm neck diameter, allows the tool to access confined features and deep pockets without interference. It is well-matched to high-speed machining centers and CNC milling applications where tight tolerances and fine surface finishes are required on hardened workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.50 mm (0.0197 inch) ball end diameter for micro-precision milling\u003c\/li\u003e\n\u003cli\u003eWXL PVD coating optimized for pre-hardened and hardened steel cutting\u003c\/li\u003e\n\u003cli\u003eUltra fine micrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 2.00 mm reach length and 0.45 mm neck diameter\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction with 30-degree medium helix\u003c\/li\u003e\n\u003cli\u003eHandles both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers accepting a 4.00 mm straight-cylindrical shank (h6 tolerance).

Confirm spindle collet or chuck bore matches the 4.00 mm shank diameter and meets h6 tolerance requirements before securing the tool. Ensure the machine is fully powered down and spindle is at rest before changing tooling. Follow the machine manufacturer's runout and tool projection specifications to maintain dimensional accuracy at this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0197 inches (0.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eOverall Length\u003c\/strong\u003e: 45.00 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 Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXL (PVD)\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 3790\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: 3110520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739741684018,"sku":"3110520","price":145.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6cbf761976ddc4b1ea7b0349ba97132c.jpg?v=1788818413","url":"https:\/\/voomisupply.com\/products\/osg-3110520-ball-end-mill-0-0197-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
