Built from M42 cobalt high-speed steel, it delivers the heat resistance and edge retention needed when cutting alloy steels, stainless steel, and other difficult-to-machine materials. The cutter measures 0.6875 inches in diameter with a 1.625-inch length of cut, a 0.5-inch Weldon flat shank, and an overall length of 3.625 inches. The 30-degree helix angle promotes efficient chip evacuation while maintaining good surface finish. This is a single-end, right-hand cut tool sold individually and suited for use in CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThe TE81237 is appropriate for general-purpose and production milling in job shops, toolrooms, and manufacturing environments. Its centercutting geometry allows plunge entry as well as conventional peripheral milling, slotting, and profiling cuts. The Weldon flat shank provides a secure, anti-pullout connection in standard end mill holders. This tool is well suited for machinists working with carbon steel, alloy steel, and stainless steel where carbide tooling is not required or where cobalt is preferred for interrupted cuts or manual-machine use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for superior heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e4 flutes with 30-degree right-hand upcut helix for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank prevents pullout in set-screw end mill holders\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — suitable as-ground for immediate use\u003c\/li\u003e\n  \u003cli\u003eFixed helix and index angles for predictable, consistent cutting behavior\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 0.5-inch Weldon flat shank end mill compatible with any end mill holder, collet chuck, or Weldon-style holder accepting a 0.5-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the tool. Secure the Weldon flat against the set screw in the holder to the appropriate holder specification to prevent axial pullout during cutting. Inspect the cutting edges for chips or wear before each use and replace when edge condition degrades to avoid workpiece damage or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches (3-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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 Upcut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: TE81237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51749594857778,"sku":"TE81237","price":87.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1a6fe57ab5eb2f9a88a935112b97450_787cfc83-afd0-4c3e-a0a2-61669b228b98.jpg?v=1788908095","url":"https:\/\/voomisupply.com\/products\/titan-usa-te81237-square-end-mill-0-6875-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
