It features a 3\/8 inch diameter cutting face, a 7\/8 inch length of cut, and a 2-1\/2 inch overall length with a matching 3\/8 inch shank. The four-flute geometry combined with a 40-degree helix angle promotes efficient chip evacuation and smooth finishes at higher feed rates. An AlTiN coating provides elevated heat and wear resistance, making this end mill well-suited for cutting high-temperature alloys, stainless steel, and steel. The centercutting design allows plunge entry into workpieces without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling machines where close-tolerance metal cutting is required. It is well suited for slotting, profiling, and peripheral milling in ferrous and high-temperature alloy materials. The right-hand cut and right-hand spiral flute configuration is the standard orientation for conventional vertical and horizontal milling setups. Micrograin carbide construction supports precise tolerances and extended tool life under consistent cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for tight tolerances and long tool life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat and oxidation resistance in high-temperature alloy and stainless steel cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a starter hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute  -  standard orientation for most milling setups\u003c\/li\u003e\n\u003cli\u003eSquare shank for secure clamping in collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8 inch collet chucks, end mill holders, or Weldon-style holders on CNC machining centers and manual knee mills.

Ensure the machine spindle is fully stopped and locked before changing tooling. Verify shank seating depth and holder concentricity before running at full speed to avoid premature tool wear or breakage. Follow the machine manufacturer and tooling manufacturer recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: AlTiN\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: +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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 111\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 111-02414\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51959276110130,"sku":"111-02414","price":92.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28ecc7cf529997f5aef4843dd40c1bbb.jpg?v=1789945607","url":"https:\/\/voomisupply.com\/products\/promax-111-02414-square-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
