It runs 5 right-hand flutes with an 18 TPI profile and carries a TiAlN coating for heat resistance and extended tool life in ferrous and non-ferrous materials. The shank diameter is 10.00 mm (0.394 inches), the cutting diameter is 10.00 mm (0.394 inches), and the overall length is 80.00 mm (3.15 inches). Coolant-through capability supports chip evacuation in deep or blind-hole applications. This tool is sized for CNC machining centers and is installed by machinists and tool-and-die professionals working in precision threading operations.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for internal thread milling on CNC vertical and horizontal machining centers in production and job-shop environments. The 9\/16-18 UNF thread form makes it appropriate for aerospace, automotive, hydraulic, and general mechanical assembly applications where fine-thread internal features are required. The helical flute geometry and TiAlN coating support use in a range of work materials including alloy steels, stainless steels, and aluminum. Coolant-through delivery aids in chip management when threading blind holes or holes with limited clearance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision threading\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life and supports higher cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design improves chip evacuation in blind and deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e5 right-hand helical flutes for smooth thread form and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003e10.00 mm shank diameter with 40.00 mm shank length (1.575 inches) for secure toolholder engagement\u003c\/li\u003e\n  \u003cli\u003e29.63 mm (1.167 inches) length of cut accommodates standard thread depth requirements for 9\/16-18 UNF features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with ER or shrink-fit toolholders accepting a 10.00 mm shank diameter.

Confirm toolholder runout is within acceptable tolerance before use, as excessive runout will degrade thread quality and tool life. Ensure the coolant-through circuit in the spindle is active and delivering adequate pressure before starting the cut. Never use this tool in a manual machine or handheld application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 10.00 mm (0.394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm (0.394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm (1.575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 29.63 mm (1.167 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80.00 mm (3.15 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.176 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: 6580452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67913903046962,"sku":"6580452","price":923.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07422b51f03e6a0a92d43574ce83282a_95a8ea57-f058-4572-b1a2-aa7fb1ba3147.jpg?v=1791246916","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6580452-thread-mill-9-16-18-unf-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
