Built to Series 33MC standards, it features a 16 mm cutting diameter, a 38 mm length of cut, and a 2.50 mm (0.0984 inch) corner radius. The AlTiN coating under the proprietary Ti-NAMITE-A designation provides heat and wear resistance suited for aggressive cutting cycles. Three helical flutes with a variable index and variable helix geometry reduce harmonic vibration and chatter during roughing passes. The single-end configuration and straight-cylindrical shank seat directly into standard end mill holders.\u003c\/p\u003e\u003cp\u003eThis end mill is configured for roughing operations on steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. The coarse pitch and right-hand flute direction make it appropriate for high metal-removal-rate roughing in both horizontal and vertical machining centers. It is a non-centercutting, single-end tool, so plunge entry is not recommended without a pre-drilled starting hole. Machinists and CNC operators in production shops, tool rooms, and job shops running ferrous and exotic alloy workpieces are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable index and variable helix geometry reduce chatter and vibration during roughing cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating (Ti-NAMITE-A) provides elevated heat resistance for dry or minimal-lubrication machining\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e2.50 mm corner radius extends edge life and reduces stress concentration at the cutting corner\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance fits standard end mill holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with end mill holders.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the end mill holder and torque the set screw or collet to the holder manufacturer's specification. Confirm runout with a dial indicator before initiating a cut, particularly for variable-helix tools where balance is geometry-dependent.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 38 mm (0.5906 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 92 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: -0.0500 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eSeries\u003c\/strong\u003e: 33MC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: End Mill Holders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.542 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: 43491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51739697119538,"sku":"43491","price":281.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/98aff98250f83fc5eaee4a835c48f989.jpg?v=1788817958","url":"https:\/\/voomisupply.com\/products\/sgs-43491-corner-radius-end-mill-16mm-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
