Part of the ECI-5-VF series, it features a 3\/8 inch (0.3750 inch) mill diameter, five flutes, and a 0.0150 inch corner radius for reduced edge chipping and improved surface finish. The AlTiCrSiN PVD coating provides thermal resistance and hardness for extended tool life in aggressive cuts. With a variable index geometry and medium-length flute design, this end mill handles both roughing and finishing passes. It is installed and operated by machinists and CNC tool setters in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The 1 inch length of cut (0.8750 inch actual), 1 inch reach length, and 3 inch overall length make it a capable option for medium-depth pocketing, profiling, and contour work. The straight-cylindrical shank with h6 tolerance mounts directly into standard collet chucks and shrink-fit holders. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating rated for steel, stainless steel, cast iron, superalloys, titanium, and hard material applications\u003c\/li\u003e\n  \u003cli\u003e0.0150 inch corner radius reduces edge stress and improves corner durability\u003c\/li\u003e\n  \u003cli\u003eFive-flute, variable index geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 1 inch reach length accommodates deeper features without tool change\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 shank diameter tolerance for precise holder fit and runout control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard toolholders accepting a 3\/8 inch straight-cylindrical shank.

The machine spindle must be fully stopped and the tool changer or spindle lock engaged before inserting or removing the end mill. Verify holder bore size matches the 3\/8 inch shank diameter and that the shank is clean and free of debris before seating. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material grade being cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrSiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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 Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-5-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738487685426,"sku":"3398371","price":118.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2251c9666d0c1dad319752becd92272_31db8c52-979c-468c-a73f-f245bd65f3bd.jpg?v=1788800178","url":"https:\/\/voomisupply.com\/products\/iscar-3398371-corner-radius-end-mill-3-8-inch-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
