Built from solid carbide and finished with a TiCN coating, this tool delivers consistent thread geometry and extended tool life in demanding materials. It carries a 1\/16-27 NPT thread specification with 27 teeth per inch and a right-hand flute direction. The 0.2130-inch cutting diameter and 0.3900-inch length of cut make it well suited for small-bore internal threading operations. Machinists and tool-and-die professionals use this mill on CNC machining centers where simultaneous thread size and pitch control is required in a single tool pass.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in applications requiring precise internal NPT thread forms in small-diameter bores, typical in fluid fitting, instrument, and pneumatic component production. The 0.3120-inch shank diameter fits standard collet and end-mill holders found on vertical and horizontal machining centers. With a 2.2500-inch overall length and a minimum nominal diameter of 0.2460 inches, it is appropriate for shallow-to-moderate depth threading where reach and rigidity are balanced. The three-flute geometry promotes chip evacuation and surface finish consistency throughout the threading pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eThree right-hand helical flutes support efficient chip removal during internal threading\u003c\/li\u003e\n  \u003cli\u003e1\/16-27 NPT thread form with 27 TPI for tapered pipe thread compatibility\u003c\/li\u003e\n  \u003cli\u003e0.2130-inch cutting diameter allows threading in small-bore applications with a minimum nominal diameter of 0.2460 inches\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — suitable for external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with standard collet or end-mill toolholding systems accepting a 0.3120-inch shank diameter.

Confirm spindle speed, feed rate, and helical pitch settings in the CAM or CNC program before cutting — incorrect parameters are the primary cause of thread-form error and tool breakage on small-diameter carbide mills. Ensure the toolholder is clean and the shank is fully seated and torqued to the holder manufacturer specification before running. Always verify thread gauge fit on a test piece before committing to production runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/16-27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\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\u003c\/strong\u003e: 27 TPI\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\u003eCutting Diameter\u003c\/strong\u003e: 0.2130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3120 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.2460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eSeries\u003c\/strong\u003e: 4130\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.036 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9041300081900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728864477490,"sku":"9041300081900","price":271.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18ae03bb1e03e12ade34477ff6cf1bb7.jpg?v=1788697107","url":"https:\/\/voomisupply.com\/products\/guhring-9041300081900-thread-mill-1-16-27-npt-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
