It features a 1 inch cutting diameter, a 3 inch length of cut, and a 0.06 inch corner radius that helps reduce stress concentrations and extend tool life on profiling and slotting operations. The 4-flute, right-hand spiral geometry with variable index pitch supports both roughing and finishing passes. An AlTiCrSiN PVD coating provides heat and wear resistance when cutting hard and abrasive materials. This tool is intended for use in CNC machining centers by machinists and tooling technicians working in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 3401191 is engineered for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. With an extended reach design, a 1 inch Weldon flat shank, and a 6 inch overall length, it suits deep-cavity and extended-reach milling applications where rigidity and runout control are critical. The medium-length flute geometry and submicron carbide grade make it well suited to tight-tolerance work on difficult-to-machine alloys. It is center-cutting, allowing direct plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron grade substrate for strength and wear resistance in hard 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\u003eVariable index 4-flute geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius reduces edge chipping and improves surface finish on profiled features\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct plunge milling without a starter hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with h6 tolerance for secure, low-runout clamping in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eExtended reach configuration with 3 inch reach length for deep-pocket and cavity work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon flat toolholders accepting a 1 inch shank diameter.

Seat the Weldon flat shank fully into the toolholder and torque the set screw to the toolholder manufacturer specification before use. Verify runout with a dial indicator after clamping. Power down and lock out the spindle before any tool change, and confirm the toolholder bore is clean and free of chips or coolant residue prior to seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (Decimal)\u003c\/strong\u003e: 1.4961 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Medium\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\u003eSeries\u003c\/strong\u003e: ECI-4-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 3401191\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728170287410,"sku":"3401191","price":947.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76aebafa75cad44d31f5c4a0535535fb_e8bc0d84-6594-46e6-bca7-fd57fe697f88.jpg?v=1788688898","url":"https:\/\/voomisupply.com\/products\/iscar-3401191-corner-radius-end-mill-1in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
