Built from M42 cobalt high-speed steel, it features an AlTiN coating that reduces friction and extends tool life in high-temperature cutting environments. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.75 inches in diameter with a 1.625-inch length of cut and a 3.625-inch overall length, this end mill suits general-purpose slotting, profiling, and peripheral milling in manual and CNC machining setups. The 0.5-inch Weldon flat shank provides a secure, anti-pullout grip in standard end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and other harder alloys where cobalt tooling outperforms standard HSS. The right-hand cut and right-hand upcut flute geometry make it a direct fit for conventional vertical machining centers and manual knee mills. The center-cutting design allows for direct plunge entry, adding versatility for applications that require both plunging and side milling in a single tool path. It is used by machinists and toolmakers in production shops and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for superior heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating reduces heat buildup and extends tool life in high-speed ferrous machining\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth cutting and efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank prevents tool pullout in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand upcut flute geometry for conventional CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard 0.5-inch end mill holders, collet chucks, and Weldon-style set-screw holders used on vertical machining centers and manual knee mills.

Power down and lock out the spindle before changing tooling. Seat the Weldon flat against the set screw in the holder to prevent axial and rotational pullout, and verify runout with a dial indicator before engaging the cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut when programming or setting up the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: TE81342\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51729617518898,"sku":"TE81342","price":119.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/acb04ca17ec1311a99feed377de8b98e_833e9b61-b057-4199-bded-9d18cd5a700f.jpg?v=1788706818","url":"https:\/\/voomisupply.com\/products\/titan-usa-te81342-square-end-mill-0-75in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
