Built from micrograin carbide stock, it delivers a 0.5 inch cutting diameter with a 1.5 inch length of cut and a 3.5 inch overall length. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces, while the zirconium nitride (ZrN) finish improves surface hardness and wear resistance for extended tool life. Three spiral flutes with a right-hand cut and right-hand flute direction make this a standard-orientation tool for conventional milling setups. The centercutting geometry allows plunge entry directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose and production milling in machine shops, toolrooms, and manufacturing environments. It fits standard 0.5 inch collets and tool holders commonly found on CNC machining centers and manual knee mills. Typical applications include slot milling, profile milling, and step cutting in ferrous and non-ferrous metals where tight dimensional tolerances are required. The micrograin carbide substrate makes it particularly effective in harder workpiece materials where high-speed steel tooling would wear prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN (zirconium nitride) coating extends tool life and improves surface finish on the cut\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eThree spiral flutes with right-hand cut and right-hand flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n  \u003cli\u003eTight mill diameter tolerance of plus 0.000 \/ minus 0.002 inches ensures consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for 0.5 inch collet systems and end mill holders on standard CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Power down and lock out the spindle before inserting or removing the tool from the collet or holder. Ensure the shank is fully seated to the required insertion depth and that the collet or set-screw holder is torqued according to the machine tool manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use; damaged carbide tooling should be replaced, not re-run.\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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 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: 3\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 \/ minus 0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 109\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: 109-03236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51979849892146,"sku":"109-03236","price":139.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/640d99b310f138fcc251ebb18da80efc.jpg?v=1789981065","url":"https:\/\/voomisupply.com\/products\/promax-109-03236-square-end-mill-0-5in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
