It features a 12 mm cutting diameter, a 26 mm length of cut, and a 0.75 mm corner radius that reduces edge chipping and extends tool life on hard workpiece materials. The tool carries an AlTiN PVD coating applied via physical vapor deposition, which improves heat resistance and wear performance at elevated cutting temperatures. With five flutes and a high helix spiral flute geometry, the 4046386 delivers efficient chip evacuation and smooth surface finishes in both roughing and finishing passes. It is intended for installation by machinists and tooling technicians in CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, and hard materials, making it well suited to precision mold, die, and general machining work where corner geometry control is critical. The straight-cylindrical shank with a 12 mm diameter is compatible with ER single angle standard collets, supporting straightforward tool setup in standard CNC spindle configurations. The single-end design with a right-hand cutting direction and right-hand flute spiral is the conventional configuration for vertical and horizontal machining center use. The UCDE series designation places it within a submicron carbide grade tooling family optimized for P, M, K, and H material application codes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 mm cutting diameter with 0.75 mm corner radius for edge strength and controlled corner geometry\u003c\/li\u003e\n\u003cli\u003e5-flute spiral design supports efficient chip flow in both roughing and finishing operations\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides thermal and oxidation resistance in high-speed steel and hard material cutting\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade substrate for improved toughness and edge retention\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 12 mm shank fits ER single angle standard collets\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, and hard materials (ISO application codes P, M, K, H)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with ER single angle standard collets.

Secure the shank in a properly sized ER collet chuck torqued to the collet manufacturer's specification. Verify runout with a dial indicator before initiating a cutting program, as excess runout accelerates edge wear on multi-flute carbide tooling. Consult the machine tool and toolholder manufacturer guidelines for maximum RPM and feed rate limits appropriate to this diameter and coating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 12 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.75 mm (0.0295 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 26 mm (1.0236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 83 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\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: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UCDE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCompatible Toolholding\u003c\/strong\u003e: ER Single Angle Standard Collets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 0.1 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4046386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732736442674,"sku":"4046386","price":208.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c63bbb6a82eabc0517f728c6048d107_6654c71c-199a-4e3b-9331-0f8759505a56.jpg?v=1788746164","url":"https:\/\/voomisupply.com\/products\/kennametal-4046386-corner-radius-end-mill-12mm-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
