Part of the TC630 series, it features a 4-flute right-hand helical configuration and an AlTiN coating for extended tool life in ferrous and hardened materials. The straight-cylindrical shank provides secure clamping in standard collet or end mill holders. At 2.244 inches overall length and 0.57 pounds, this tool is suited for CNC machining centers where rigid, accurate thread milling is required. Installation and operation are performed by machinists and tooling specialists working within established CNC programming parameters.\u003c\/p\u003e\u003cp\u003eThis thread mill is used in production and job-shop environments requiring clean, accurate internal UNF threads. Thread milling with a helical flute design allows a single tool to produce a range of thread sizes in one helical interpolation pass, reducing tooling inventory and improving thread quality in difficult-to-machine materials. It is appropriate for use in vertical and horizontal machining centers with helical interpolation capability. The AlTiN coating supports dry or near-dry cutting conditions where heat resistance is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding thread milling operations\u003c\/li\u003e\n\u003cli\u003eAlTiN coating enhances heat resistance and tool life in ferrous and hardened workpiece materials\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand helical flute design for efficient chip evacuation during internal thread milling\u003c\/li\u003e\n\u003cli\u003eInternal UNF thread standard compatibility for unified fine pitch thread applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for secure, repeatable clamping in collet chucks or end mill holders\u003c\/li\u003e\n\u003cli\u003eTC630 series design supports helical interpolation on CNC machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation for cutting internal UNF threads.

Secure the straight-cylindrical shank in a properly sized collet or end mill holder, verifying runout before cutting. Program helical interpolation passes per the machine tool builder and tooling manufacturer specifications. Inspect the cutting edges before use and do not operate a chipped or damaged tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eSeries\u003c\/strong\u003e: TC630\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 8120200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67917812597042,"sku":"8120200","price":340.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9035c68ad59381f0001fe93e868e8288_454b3876-6372-485d-9300-28974479a05e.jpg?v=1791265517","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-8120200-helical-flute-thread-mill-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
