Built from submicron-grade solid carbide, the tool delivers the rigidity and edge retention required for threading operations in ferrous and non-ferrous materials. It runs a 0.74-inch cutting diameter with a 1.08-inch length of cut, giving technicians and machinists adequate reach for standard-depth threaded bores. The bright, uncoated finish suits general-purpose applications where coating is not required by the workpiece material. Four straight flutes support chip evacuation in typical CNC machining center setups.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in CNC machining environments where a single tool must produce a complete internal thread form without a dedicated tap. It is suited for job shops, production machining, and maintenance repair operations requiring 1-12 UNF internal threads. The 3\/4-inch shank interfaces directly with standard ER or end mill holders. At 6 inches overall length, the tool accommodates setups where moderate reach from the spindle face is needed. Coolant-through is not supported, so external or flood coolant is the standard approach during operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for edge retention and tool rigidity\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry with 4 flutes for controlled chip flow on internal thread forms\u003c\/li\u003e\n\u003cli\u003eCuts 1-12 UNF internal threads with a 0.74-inch cutting diameter\u003c\/li\u003e\n\u003cli\u003e1.08-inch length of cut supports standard-depth threaded bores\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for general-purpose threading applications\u003c\/li\u003e\n\u003cli\u003e3\/4-inch shank diameter compatible with standard CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation; fits standard 3\/4-inch ER collet chucks and end mill holders used in production and job shop threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist or CNC programmer familiar with thread milling cycles and helical interpolation. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing the tool. Verify holder runout and tool projection before initiating a threading cycle, as excessive runout will affect thread quality. Apply flood or external mist coolant directed at the cutting zone; this tool does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 12 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.74 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.08 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStaggered Tooth\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMC 740-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51959117545778,"sku":"TMC 740-12","price":306.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c944502cd068891c5b6b7ac1a9df3c6b.jpg?v=1789945489","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmc-740-12-thread-mill-1-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
