Built from solid carbide with a TiN coating, it features a 12 mm cutting diameter, a 2.50 mm (0.0984 inches) corner radius, and six helical flutes arranged in a close-pitch, variable-index pattern. The 26 mm length of cut and 83 mm overall length make it well-suited for controlled, high-accuracy passes on ferrous and exotic alloys. Right-hand cutting and right-hand flute direction are standard. It fits directly into standard end mill holders with a straight-cylindrical 12 mm shank.\u003c\/p\u003e\u003cp\u003eThis end mill targets finishing operations on steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. Its variable index design helps reduce harmonic chatter during long finishing passes, and the close-pitch flute layout supports smooth surface finishes on tight-tolerance features. It is intended for use by machinists and toolroom professionals working in CNC milling environments where corner geometry control is critical. The Series 51CR designation identifies it within the SGS extended corner radius product line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiN coating to extend tool life on ferrous and exotic alloy workpieces\u003c\/li\u003e\n\u003cli\u003e2.50 mm corner radius with a tight tolerance of -0.0500 to 0.0000 mm for predictable geometry\u003c\/li\u003e\n\u003cli\u003eVariable index flutes reduce chatter and improve surface finish quality\u003c\/li\u003e\n\u003cli\u003eSix-flute, close-pitch design optimized for finishing cuts\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 12 mm shank with h6 tolerance for secure holder fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders.

Ensure the holder bore and shank are clean and free of debris before seating the tool. Verify spindle direction is set to right-hand rotation before engaging the cut. Because this tool is not centercut, avoid axial plunge moves  -  use ramping or helical interpolation for entry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0500 to 0.0000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0508 to 0.0000 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 26 mm (0.5118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 83 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\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\u003eChipbreaker\u003c\/strong\u003e: No\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\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; 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\u003eSeries\u003c\/strong\u003e: 51CR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.284 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.27 inches (L) x 0.71 inches (W) x 0.71 inches (H)\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: 45178\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51740152398130,"sku":"45178","price":199.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42417fcdd700ed307d41be08971a4e68_ce9a1ffe-3610-4662-8ac0-68bdd8e3c80c.jpg?v=1788822958","url":"https:\/\/voomisupply.com\/products\/sgs-45178-corner-radius-end-mill-12mm-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
