Built from submicron-grade carbide with a TiAlN finish, this insert delivers consistent thread geometry and wear resistance in demanding production environments. The MT7 manufacturer grade indicates a specific coating and substrate combination suited for a range of workpiece materials. Machinists and CNC programmers working in job shops, production facilities, or maintenance environments install this insert into compatible thread milling toolholders to generate precise external UN threads.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for external thread milling on UN thread form applications at 8 TPI. The non-conical (straight) profile makes it appropriate for standard thread milling cycles on CNC machining centers. It is sized for use in industrial thread milling applications where consistent insert geometry and predictable tool life are required. The insert style designation 40E defines the geometry and seating configuration for compatible toolholder systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron carbide substrate for improved edge toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN finish provides thermal protection during high-speed thread milling\u003c\/li\u003e\n\u003cli\u003eExternal UN thread form at 8 TPI for standard unified national thread applications\u003c\/li\u003e\n\u003cli\u003eNon-conical profile suits standard CNC thread milling cycles\u003c\/li\u003e\n\u003cli\u003eMT7 grade designation ensures consistent coating and substrate performance\u003c\/li\u003e\n\u003cli\u003eInsert style 40E for precise seating and repeatability in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with compatible CARMEX thread milling toolholders that accept the 40E insert style.

Ensure the machine spindle is fully stopped and the tool is secured before changing inserts. Use the appropriate torx or hex key to seat the insert correctly against the toolholder pocket  -  do not overtighten the clamping screw. Confirm insert seating and runout before initiating a thread milling cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 40E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MT7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConical\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2480 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40E8UNMT7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51991794614578,"sku":"40E8UNMT7","price":454.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc6908409fb5b182fa48a7b3afcdafa2_eb3283c5-4b1e-4b9d-a6c8-3aea67bdf2b5.jpg?v=1789989907","url":"https:\/\/voomisupply.com\/products\/carmex-40e8unmt7-carbide-thread-mill-insert-un-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
