It features a 3\/8 inch cutting diameter, a 1-1\/2 inch length of cut, and a 6 inch overall length, making it well-suited for deep-reach applications where rigidity and tool life are critical. The four-flute configuration with a 30-degree spiral helix provides efficient chip evacuation and a smooth cutting action. A titanium nitride (TiN) finish enhances surface hardness and extends tool life in ferrous and non-ferrous materials. This end mill is centercutting, allowing plunge operations in addition to peripheral and slot milling. Installed by machinists and tool-and-die professionals operating manual or CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose milling on vertical and horizontal milling machines and CNC machining centers. It performs well in applications including side milling, slotting, profiling, and light plunging in steel, aluminum, cast iron, and similar materials. The right-hand cut and right-hand flute orientation are standard for conventional and climb milling setups. The 3\/8 inch shank diameter is compatible with standard collet chucks, end mill holders, and milling arbors of the same bore size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral design with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge and ramp entry cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for standard milling machine spindle direction\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 3\/8 inch shank matching the cutting diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard milling machine collet systems and end mill holders with a 3\/8 inch bore.

Secure the shank fully into a clean, properly sized collet or end mill holder and torque the retention mechanism according to the holder manufacturer specifications before spindle engagement. Inspect the collet and holder for runout before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish. Never exceed the tool manufacturer recommended speeds and feeds for the material being machined.\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 inch (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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.65 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730825118002,"sku":"750502","price":124.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4166c3753f24be7485ac9f55c57d237.jpg?v=1788723441","url":"https:\/\/voomisupply.com\/products\/hertel-750502-square-end-mill-3-8-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
