Built on the TC630 series platform, it features 4 right-hand flutes and an AlTiN coating that extends tool life in ferrous and high-temp alloy applications. With an overall length of 2.244 inches and a straight-cylindrical shank, this tool mounts directly in standard milling chucks or collet holders. It is suited for CNC machining centers running thread milling cycles where tapping is impractical or where a single tool must cover a range of thread depths.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is intended for internal thread milling operations on CNC machining centers. The helical flute geometry and AlTiN coating make it well-suited for interrupted cuts, blind holes, and materials where conventional tapping presents breakage risk. The right-hand flute direction supports standard climb or conventional milling strategies as programmed in the thread milling cycle. Typical applications include production machining of ferrous components requiring UNC internal threads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 helical flutes for improved chip evacuation during internal thread milling\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides heat resistance and extended tool life in ferrous and alloy materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard collet and milling chuck toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction suits standard CNC thread milling interpolation cycles\u003c\/li\u003e\n  \u003cli\u003eTC630 series design optimized for internal UNC thread forms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for internal UNC thread milling operations on CNC machining centers equipped with helical interpolation capability and standard straight-bore toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified CNC machinist or tooling technician. Secure the straight-cylindrical shank in a properly sized collet or milling chuck and verify runout before cutting. Program the thread milling cycle according to the machine control and workpiece thread specification  -  do not use this tool in a rigid tapping cycle. Inspect the cutting edges for wear or chipping before each use and replace when tool life criteria are met.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TC630\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: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.244 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.57 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\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: WALTER-PROTOTYP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8120184\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67908225728818,"sku":"8120184","price":326.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760fe6b7c7b3579bbb09c3d57bb90fc1.jpg?v=1791182905","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-8120184-internal-thread-mill-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
