With a 5.5 mm (0.2165 inch) cutting diameter and a 16 mm (0.6299 inch) length of cut, this tool handles slotting, profiling, and peripheral milling in demanding shop environments. The AlTiN coating improves heat resistance and extends tool life at elevated cutting speeds. Four right-hand flutes with a 30-degree helix angle promote efficient chip evacuation. The micrograin carbide substrate provides hardness and edge retention. Machinists and CNC operators in job shops, production facilities, and toolrooms are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill suits applications in steel, stainless steel, cast iron, and high-temperature alloys where a tough, heat-resistant coating is required. The 6 mm (0.2362 inch) shank diameter fits standard ER collet chucks and end mill holders. At 50 mm (1.969 inch) overall length with no extended reach geometry, it is sized for rigidity in shallow to mid-depth cuts. Center-cutting capability allows direct plunge entry. The upcut flute geometry evacuates chips away from the workpiece surface, reducing re-cutting in slot and pocket operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.5 mm (0.2165 inch) cutting diameter with a 16 mm length of cut\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4 right-hand flutes, 30-degree helix angle, upcut flute geometry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e6 mm shank diameter, 50 mm overall length, single-end configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard ER collet chucks and end mill holders accepting a 6 mm shank diameter, suitable for CNC machining centers and manual knee mills configured for metric tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank in a clean, properly sized collet or end mill holder to the full recommended grip depth before torquing the retention mechanism. Verify spindle runout with a dial indicator before beginning a cut to maximize tool life and surface finish. Always power down and lock out the spindle before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5.5 mm (0.2165 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm (1.969 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eFlute Type\u003c\/strong\u003e: Upcut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.15 inches L x 0.43 inches W x 0.43 inches H\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: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC11981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51735654793522,"sku":"TC11981","price":53.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/966c72aa4e5a5d612010a0548acc9abc_1b1a9b77-d7c5-4a77-b2b3-16a3c1522fb9.jpg?v=1788773475","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc11981-square-end-mill-5-5mm-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
