With a 9.90 mm cutting diameter, 18 teeth per inch (TPI), and a TiCN coating for extended tool life and heat resistance, this mill produces accurate internal threads in a single helical pass. The 3-flute right-hand configuration provides a stable cutting action with efficient chip evacuation. Machinists and CNC operators working in job shops, production facilities, and aerospace or general manufacturing environments will find this tool suited for demanding threading applications.\u003c\/p\u003e\u003cp\u003eThis thread mill is intended for internal thread milling operations on CNC machining centers where helical interpolation is available. The 10.00 mm shank diameter fits standard ER or hydraulic toolholders commonly used in vertical and horizontal machining centers. With a 15.92 mm length of cut and 66.00 mm overall length, it is well suited for threading shallow to mid-depth bores. No coolant-through capability is present, so external coolant or air blast is recommended for chip management during operation.\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 applications\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e3 right-hand flutes with helical geometry for smooth cutting action and controlled chip flow\u003c\/li\u003e\n\u003cli\u003e18 TPI for standard thread pitches commonly encountered in general machining\u003c\/li\u003e\n\u003cli\u003e9.90 mm cutting diameter with a -0.30 mm tolerance for controlled thread form accuracy\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design  -  compatible with external flood or mist coolant setups\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 internal thread milling operations with a 10.00 mm shank interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified CNC machinists or tooling technicians. Secure the shank in an appropriate precision toolholder and verify runout before use, as excessive runout will degrade thread quality and shorten tool life. Confirm that the machining center control supports helical interpolation before programming the thread milling cycle. Always follow machine manufacturer lockout and tool-change procedures when installing or removing the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 18 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 9.90 mm (0.3898 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter Tolerance\u003c\/strong\u003e: -0.30 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 15.92 mm (0.6268 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 5160615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67907340828978,"sku":"5160615","price":1000.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74e45d4a3d3e06d7d8c57a511d23eb3a.jpg?v=1791177701","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-5160615-internal-thread-mill-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
