It features a 3\/8 inch cutting diameter, a 3\/4 inch length of cut (LOC), and a 0.03 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life. The 5-flute, right-hand spiral design with a variable pitch promotes chip evacuation and dampens harmonics during high-speed cutting passes. An AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures. This tool is used by machinists and CNC operators working in job shops, tool rooms, and production environments.\u003c\/p\u003e\u003cp\u003eThe SGS 37189 is suited for milling ferrous metals, stainless steels, and high-temperature alloys where edge strength and surface finish are critical. Its regular-length geometry makes it a practical choice for profiling, slotting, and contouring on vertical and horizontal machining centers. The 3\/8 inch shank diameter fits standard ER collet chucks and end mill holders common to most CNC mills. The Z5CR series designation identifies it as a 5-flute corner radius tool within the SGS variable-pitch line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and improves surface finish\u003c\/li\u003e\n\u003cli\u003e5-flute variable-pitch design minimizes chatter at high feed rates\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and tool longevity in ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for conventional CNC milling setups\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard 3\/8 inch shank end mill holders and ER collet systems on CNC vertical and horizontal machining centers.

Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge-line depth and torque the retention nut per the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Variable\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\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Z5CR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.131 pounds\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: 37189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51729043259698,"sku":"37189","price":127.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/925ad1f702d03338ca88803411389385.jpg?v=1788699180","url":"https:\/\/voomisupply.com\/products\/sgs-37189-corner-radius-end-mill-3-8-in-5-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
