Built from micrograin carbide and finished with a zirconium nitride (ZrN) coating, this tool delivers extended wear resistance and improved surface finish in demanding cutting environments. It features a 0.5-inch cutting diameter, a 1.25-inch length of cut, and a 3-inch overall length. The 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and smooth cutting action. Licensed machinists and CNC operators in job shop, production, and tool room settings are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling applications in ferrous and non-ferrous metals, plastics, and composites where a long-reach configuration is required. The centercutting design allows for plunge entry as well as standard peripheral milling. Right-hand cut and right-hand flute orientation make it compatible with standard spindle configurations on vertical and horizontal machining centers as well as knee mills. The long series classification provides additional reach for deep pocket and stepped-feature work that shorter tools cannot access.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eLong series length provides extra reach for deep pockets and stepped features\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 0.5-inch shank square end mill applications on standard CNC machining centers and manual mills using ER or similar collet systems sized for 0.5-inch tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked before inserting or removing tooling. Seat the 0.5-inch shank fully into the collet or tool holder and torque the retention nut to the tool holder specification before operation. Verify runout with a dial indicator before beginning a production run to confirm proper seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\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: 0.5 inches\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Square\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 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 108\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 108-03216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52007533445426,"sku":"108-03216","price":109.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c92901fc0958c8b00a8de1bf64ced1a8.jpg?v=1790001809","url":"https:\/\/voomisupply.com\/products\/promax-108-03216-square-end-mill-1-2-in-2-flute-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
