It carries a 3\/8-inch mill diameter with a 1-inch length of cut and a 3-inch overall length. The APLUS PVD coating improves heat resistance and wear life in ferrous materials. Variable index flute spacing reduces harmonic chatter during aggressive cuts, making this tool well-suited for both roughing and finishing passes. Licensed machinists and CNC programmers working in job shop or production environments will find this tool a direct fit for demanding steel-cutting applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for cutting steel, stainless steel, tool steels, and cast iron in CNC machining centers and manual mills. The single-end, straight-cylindrical shank with a 3\/8-inch shank diameter mounts directly into standard collets and end mill holders. The standard-length design fits typical vertical and horizontal machining center setups without requiring extended-reach toolholders. It handles both roughing and finishing operations in a single tool, reducing the need for multiple setups on ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-flute ball nose geometry supports both roughing and finishing in steels and cast iron\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and improves surface finish during interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating extends tool life in ferrous and high-temperature alloy materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and heat resistance over high-speed steel alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003e0.1875-inch nose radius enables contoured and 3D surface milling with consistent ball geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel (P), stainless steel (M), and cast iron (K) workpiece materials as defined by ISO material classification codes.

Seat the shank fully into the collet or holder and torque the retention nut to the toolholder manufacturer's specification. Verify runout against the published TIR maximum of 0.0005 inches before beginning the cut. Inspect the cutting edges for coating damage or chipping before each use, particularly after interrupted cuts in hardened steels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: APLUS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: 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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +\/- 0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.148 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 56337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51740528345394,"sku":"56337","price":108.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9c8bc55c4f31badf2181f4032989dca_93d3c092-2130-4892-965b-2464abbd822c.jpg?v=1788825704","url":"https:\/\/voomisupply.com\/products\/helical-solutions-56337-ball-end-mill-3-8in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
