Built from solid carbide and finished with OSG EXO coating, this tool delivers hardness and heat resistance well suited for production threading in ferrous and non-ferrous materials. The four right-hand flutes provide smooth chip evacuation and stable cutting action. With a 0.3700-inch cutting diameter and a 3\/4-inch length of cut, this mill handles standard thread depths efficiently. A 3\/8-inch shank diameter keeps the tool compatible with common ER collet and side-lock holders found in most machining centers.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is intended for use in CNC machining centers by machinists and tool and die professionals producing UNF threads in precision components. The helical flute geometry suits both through-hole and blind-hole thread applications where tap breakage risk must be minimized. At 3 inches overall length, the tool provides adequate reach for typical workpiece setups without excessive overhang. It is sold individually and belongs to OSG Series 41000.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding thread milling operations\u003c\/li\u003e\n  \u003cli\u003eEXO coating reduces friction and extends tool life in hardened and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes promote efficient chip flow and surface finish quality\u003c\/li\u003e\n  \u003cli\u003e0.3700-inch cutting diameter matched to 1\/2-20 UNF thread form at 20 TPI\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter fits standard ER collet holders and side-lock tooling\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design simplifies setup; external coolant or air blast is recommended\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers capable of helical interpolation; fits 3\/8-inch ER collet or side-lock tool holders.

Secure the shank fully in a balanced tool holder and confirm runout before cutting. Follow the machine tool manufacturer and OSG recommended feeds and speeds for the specific workpiece material. No coolant-through path is present on this tool; apply external flood coolant or air blast to manage chip evacuation and heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 20\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\u003eCutting Diameter\u003c\/strong\u003e: 0.3700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5000 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: EXO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 41000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4100001711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51745565638962,"sku":"4100001711","price":640.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01cfe3d2e26dfa79968727756138b354.jpg?v=1788864460","url":"https:\/\/voomisupply.com\/products\/osg-4100001711-thread-mill-1-2-20-unf-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
