It runs 3 right-hand flutes at 28 teeth per inch and covers a cutting diameter of 0.2400 inches with a length of cut of 0.5720 inches. The tool carries a TiAlN coating for heat resistance and extended tool life in steel, cast iron, and similar ferrous workpiece materials. With an overall length of 2.5000 inches and a 1\/4-inch shank diameter, it fits standard ER and end mill holders common in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis thread mill suits machinists and CNC programmers working with British Standard Pipe Parallel thread forms in aerospace, hydraulic, and fluid-system component manufacturing. The helical flute geometry supports a single-pass or multi-pass helical interpolation strategy depending on the machining center's capabilities and the required thread tolerance. It is appropriate for threading small-diameter holes and bosses where tap breakage risk makes a thread mill the preferred tool. No coolant-through capability is present, so flood or mist coolant applied externally at the spindle is standard practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts both internal and external BSPP threads in a single tool\u003c\/li\u003e\n  \u003cli\u003e28 TPI thread form matches British Standard Pipe Parallel specifications\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves wear resistance and heat tolerance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e3-flute right-hand helical design promotes chip evacuation during interpolation cycles\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity for tight-tolerance thread profiles\u003c\/li\u003e\n  \u003cli\u003eMinimum nominal diameter of 0.0625 inches supports threading very small features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC machining centers capable of helical interpolation.

Ensure the tool is seated and torqued correctly in the holder per the holder manufacturer's specifications before spindle engagement. Power down and lock out the machining center before changing or inspecting the tool. Verify thread pitch and diameter with appropriate gauging after the first article cut before running production quantities.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.2400 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5720 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\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 28 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\u003eThread Standard\u003c\/strong\u003e: BSPP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and External\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: 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: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.5 inches length, 1 inch width, 1 inch height\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: ALLIED MACHINE AND ENGINEERING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TM28BSPP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ALLIED MACHINE AND ENGINEERING","offers":[{"title":"Default Title","offer_id":51737447727410,"sku":"TM28BSPP","price":222.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/341709a71f91567d358164f4c5c375cb_f75d70ad-399e-490c-80d3-f0ab8ef552a7.jpg?v=1788788687","url":"https:\/\/voomisupply.com\/products\/allied-machine-tm28bspp-thread-mill-28-tpi-bspp-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
