Built on the Series 33MCR platform, it features a 4 mm cutting diameter, a 0.3 mm corner radius, and a 12 mm length of cut. The variable helix geometry and coarse pitch flute configuration reduce chatter and improve chip evacuation during roughing operations. An AlTiN coating — SGS proprietary designation Ti-NAMITE-A — delivers elevated heat and wear resistance. This tool is intended for use by machinists and tool-and-die professionals working in CNC milling environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing applications in ferrous and exotic alloy materials at the small-diameter end of the spectrum. The 4 mm diameter and 6 mm straight-cylindrical shank make it compatible with standard end mill holders used in CNC machining centers handling precision component work. The single-end, right-hand cutting configuration is standard for conventional and climb milling setups. It is well matched to applications in aerospace, mold and die, and general metalworking shops where tight corner geometry and material hardness drive tooling selection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating (Ti-NAMITE-A) for high-heat and wear resistance in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eVariable helix design reduces harmonic vibration and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003e0.3 mm corner radius extends tool life and reduces stress concentration at cutting edges\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity at small diameters\u003c\/li\u003e\n\u003cli\u003eCoarse pitch geometry optimized for roughing and material removal rate\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction with centercutting geometry for versatile entry strategies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders.

Seat the 6 mm straight-cylindrical shank fully into a clean, properly sized end mill holder and torque the retention mechanism to the holder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, as excessive runout at small diameters accelerates edge wear. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.3 mm (0.0118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 12 mm (1.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0300 to 0.0000 mm\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 33MCR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 43446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51755067081010,"sku":"43446","price":68.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cc63e08eaab4c02447c76f153b6c6b9_cd66f87f-f1ae-42e1-8325-85069c06b3c0.jpg?v=1788950845","url":"https:\/\/voomisupply.com\/products\/sgs-43446-corner-radius-end-mill-4mm-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
