Built from submicron-grade solid carbide, it delivers consistent thread geometry and edge retention in ferrous and non-ferrous materials. The tool features 3 flutes, a 0.14 inch cutting diameter, and a 0.388 inch length of cut, making it suited for threading shallow blind holes and through-hole applications where tight pitch accuracy is required. The bright finish reduces built-up edge and supports chip evacuation in close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in CNC machining centers for producing internal UNF threads starting at the No. 10 minimum nominal diameter. It is applicable in precision manufacturing environments including aerospace, automotive, and general metalworking shops where thread milling is preferred over tapping for improved thread quality, tool life, or access in hardened or difficult-to-tap materials. The 1\/4 inch shank diameter fits standard ER and end mill collet toolholding systems common in vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for extended tool life and edge stability\u003c\/li\u003e\n  \u003cli\u003e3 straight flutes with bright finish for reduced friction and chip buildup\u003c\/li\u003e\n  \u003cli\u003eCuts internal 10 to 32 UNF threads in a single helical interpolation pass\u003c\/li\u003e\n  \u003cli\u003e0.14 inch cutting diameter with 0.388 inch length of cut for shallow-hole applications\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter for compatibility with standard collet toolholding\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; suitable for flood or mist coolant delivery externally\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation.

Secure the shank fully in a collet or end mill holder to the recommended grip depth to minimize runout. Ensure the workpiece is rigidly fixtured, as deflection under cutting load will affect thread pitch diameter accuracy. Follow shop-standard feeds, speeds, and depth-of-cut parameters for solid carbide thread mills in the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10 to 32\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: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 32 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.388 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStaggered Tooth\u003c\/strong\u003e: No\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: 0.5 pounds\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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM140-32\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52040306131250,"sku":"TM140-32","price":177.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24b2de33dc9cd61a8806f3d46b80d219.jpg?v=1790026927","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tm140-32-thread-mill-10-32-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
