Built from micrograin solid carbide and coated with TiCN, this tool handles demanding threading operations where tool life and thread quality are critical. The 4-flute, right-hand helical configuration provides smooth chip evacuation and consistent thread form. With a cutting diameter of 0.2850 inches, a 0.7500-inch length of cut, and an overall length of 2.9920 inches, it fits standard CNC machining center setups. Machinists and CNC operators in production and job-shop environments rely on thread mills like this when tapping is not practical or when through-hole and blind-hole flexibility is required.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for internal threading operations on CNC machining centers using helical interpolation. The 3\/8-16 UN thread standard makes it applicable to general fastener threads common in mechanical assemblies, fixturing, and structural components. The 5\/16-inch shank diameter fits standard ER or similar toolholding collets. It is appropriate for use in ferrous and non-ferrous workpiece materials where a TiCN coating provides adequate wear resistance and reduces built-up edge. Production machinists, tool-and-die makers, and precision job shops are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in steel and other ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand helical geometry promotes chip flow and consistent thread form\u003c\/li\u003e\n\u003cli\u003e0.2850-inch cutting diameter sized for 3\/8-16 internal UN thread production\u003c\/li\u003e\n\u003cli\u003e0.7500-inch length of cut accommodates typical thread depth requirements for 3\/8-16 fastener threads\u003c\/li\u003e\n\u003cli\u003e2.9920-inch overall length provides clearance reach in standard machining center setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation for cutting internal 3\/8-16 UN threads.

Secure the shank in a properly sized, balanced collet chuck and verify runout before cutting. Program the CNC controller for helical interpolation at the correct pitch for 3\/8-16 UN threads. Always confirm workpiece is securely fixtured and spindle is at a full stop before changing or inspecting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 16 TPI\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: 0.2850 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9920 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\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: Micrograin\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 Dimensions\u003c\/strong\u003e: 3.5 inches L x 0.71 inches W x 0.71 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.193 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: VARGUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 80548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VARGUS","offers":[{"title":"Default Title","offer_id":67916211552562,"sku":"80548","price":259.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4af45bb783fdd97bc1e8a4a5fdc35470_ecef7f51-e316-4717-9179-ab9b95b9d742.jpg?v=1791256516","url":"https:\/\/voomisupply.com\/products\/vargus-80548-thread-mill-3-8-16-internal-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
