With a 3\/4 inch mill diameter, 1-1\/2 inch length of cut, 4-inch overall length, and a 1\/8 inch corner radius, this tool handles both roughing and finishing operations in a single setup. The 4-flute, right-hand helical configuration paired with a variable index and variable helix geometry reduces chatter and improves surface finish at higher feed rates. An AlTiN (TX) coating provides thermal and wear resistance for cutting in ferrous and hard materials without coolant through the tool.\u003c\/p\u003e\u003cp\u003eThe SGS 36389 is suited for machining steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. It is intended for use in CNC milling centers with end mill holders using a straight-cylindrical shank. The short flute length relative to diameter makes it rigid enough for slotting, profiling, and corner-radius contouring where tool deflection must be minimized. Licensed machinists and CNC programmers working in job shops, aerospace, and general metalworking will find this a practical choice for multi-material production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch mill diameter with matching 3\/4 inch straight-cylindrical shank for consistent runout in standard end mill holders\u003c\/li\u003e\n\u003cli\u003e1\/8 inch corner radius reduces stress concentrations at part corners and extends tool life compared to sharp-corner end mills\u003c\/li\u003e\n\u003cli\u003eVariable index and variable helix geometry reduces harmonic vibration and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN (TX) coating delivers high-temperature hardness and oxidation resistance for dry or near-dry machining\u003c\/li\u003e\n\u003cli\u003eRated for roughing and finishing in a single tool across steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cutting direction; no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders accepting a 3\/4 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended engagement depth in the end mill holder and torque the set screw or collet per the holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, as runout beyond acceptable limits will accelerate wear and reduce corner radius tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eShank 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 (0.7500 inches per decimal reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 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\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (TX)\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, 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eChipbreaker\u003c\/strong\u003e: No\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: ZPCR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 36389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51742310564146,"sku":"36389","price":448.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d780d2745072a677c30cf58d4ef2fc44_21d09ea9-44be-46b8-96fa-1af7643a0e13.jpg?v=1788836667","url":"https:\/\/voomisupply.com\/products\/sgs-36389-corner-radius-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
