Built to the MTECS-UN series standard, this long-reach tool carries a TiAlN coating that extends tool life in ferrous and hardened materials. It runs a 0.1870-inch cutting diameter on a 0.2500-inch straight-cylindrical shank, with a 0.5500-inch length of cut and an overall length of 2.5000 inches. The three-flute, right-hand configuration suits CNC machining centers in job shop, production, and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis thread mill is applied where tapped-hole flexibility or thread quality demands exceed what a standard tap can deliver. It is suited for blind holes, through holes, and interrupted-thread applications requiring a 1\/4-inch UN thread at 20 teeth per inch. The long-reach geometry allows access to recessed features and deeper boss patterns common in fixture plates, manifold blocks, and structural weldments. Machinists and CNC programmers working in aerospace, general manufacturing, and precision machining typically specify this tool for multi-diameter thread-milling strategies on CNC vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in material grade IN2005 for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces heat buildup and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eThree helical flutes, right-hand cut, for smooth chip evacuation during thread interpolation\u003c\/li\u003e\n\u003cli\u003eLong-reach design with 1.9500-inch shank length provides access to recessed features\u003c\/li\u003e\n\u003cli\u003eCuts 1\/4-inch UN thread form at 20 teeth per inch in a single CNC interpolation pass\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard ER and hydraulic collet 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.

Secure the shank in a balanced, properly torqued collet or toolholder before spindle operation. Program helical interpolation per the tool manufacturer's recommended cutter compensation and feed-per-tooth values for the workpiece material. Inspect runout at the cutting diameter before first use, as excessive runout accelerates flute wear and degrades thread quality.\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\u003eMaterial Grade\u003c\/strong\u003e: IN2005\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MTECS-UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.1870 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.9500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 0.23 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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2946060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972241686834,"sku":"2946060","price":283.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1620f839cf9da6cec81621038acc3586_4454d51a-01b7-469d-a248-e9d34f73299c.jpg?v=1789964818","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-2946060-thread-mill-1-4-un","provider":"Voomi Supply","version":"1.0","type":"link"}
