Built from micrograin carbide and finished with a PVD-applied AlTiN coating, this tool delivers hardness and heat resistance suited for steel, stainless steel, superalloys, and titanium. The 4-flute, single-end geometry with a 0.02-inch corner radius and high helix angle supports both roughing and finishing operations in a single tool. It measures 0.625 inches in diameter with a 2.5-inch overall length. Licensed machinists and CNC programmers working in precision manufacturing environments are the primary users of this end mill.\u003c\/p\u003e\n\u003cp\u003eThe 156-32414 is intended for milling steel, stainless steel, superalloys, and titanium in production and job-shop environments. Its short-length flute configuration and coarse pitch make it well suited for slotting, profiling, and contouring operations where rigidity and chip evacuation are priorities. The straight-cylindrical shank seats into standard toolholders, making it compatible with most CNC machining centers and manual mills running right-hand cutting operations. It is not intended for center drilling but is center-cutting capable for plunge entry when required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for high-heat applications including titanium and superalloys\u003c\/li\u003e\n  \u003cli\u003e0.02-inch corner radius reduces stress concentration and extends tool life at corners\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral geometry supports roughing and finishing in a single pass\u003c\/li\u003e\n  \u003cli\u003eHigh helix angle promotes efficient chip evacuation in deep-cavity cuts\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard straight-cylindrical toolholders.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Seat the shank fully into the collet or toolholder bore and verify runout before engaging the workpiece. Do not exceed the recommended depth of cut for the tool diameter, and confirm coolant strategy matches the AlTiN coating requirements, as this coating is optimized for dry or minimum-quantity lubrication cutting conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.001 to 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.002 to 0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 156\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 156-32414\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51959241834802,"sku":"156-32414","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a346e568398b44b27e2f82db283b9f5e.jpg?v=1789945588","url":"https:\/\/voomisupply.com\/products\/promax-156-32414-corner-radius-end-mill-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
