Built on the Series 01C platform with a Ti-NAMITE-A AlTiN coating, it handles both roughing and finishing operations in a single tool. The cutter features a 3\/4 inch mill diameter, a 1-1\/2 inch length of cut, and a 0.0600 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life. The 4-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and stable, vibration-resistant cuts. Variable index spacing further reduces chatter during aggressive passes. The 3\/4 inch Weldon flat shank seats securely in standard end mill toolholders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard secondary materials. Its short length type and rigid micrograin carbide substrate make it appropriate for production environments where tool deflection and runout must be tightly controlled. Typical applications include shoulder milling, slotting, and profiling on CNC machining centers. The Weldon flat shank is compatible with standard end mill toolholders commonly found in both job shop and high-volume production settings. The tool is single-end, non-centercutting, and does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN Ti-NAMITE-A coating for extended tool life in steel, stainless, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e0.0600 inch corner radius reduces edge chipping and stress at the cutting corner\u003c\/li\u003e\n  \u003cli\u003eVariable index, 4-flute geometry minimizes chatter during roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle promotes chip flow in a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides hardness and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank ensures positive engagement and prevents pullout in end mill toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill toolholders accepting a 3\/4 inch Weldon flat shank.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting. Torque the Weldon flat setscrew according to the toolholder manufacturer specification. Verify runout at the cutting diameter before beginning the first pass, as excessive runout will accelerate edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\u003eOverall Length\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00000 to -0.00200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 01C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 inches L x 1.22 inches W x 1.22 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 38189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51752986050866,"sku":"38189","price":400.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dadd864cce4fc3f0607d6d40abec498_bb78b2b7-34df-4fff-9a78-2872aa49e1bf.jpg?v=1788931865","url":"https:\/\/voomisupply.com\/products\/sgs-38189-corner-radius-end-mill-3-4in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
