Manufactured from micrograin carbide and finished with a TiAlN coating, this tool delivers hardness and heat resistance suited to ferrous and non-ferrous workpiece materials. It runs a 3-flute, right-hand flute direction configuration with a cutting diameter of 0.235 inches and a length of cut of 0.625 inches. The 0.315-inch minimum nominal bore diameter and 6.00 mm shank make this tool compatible with standard collet and end mill holders. Coolant-through capability is not available on this model.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in CNC machining centers for interpolating internal M8x1.25 threads in production and job-shop environments. It is suited for applications where a tap would be at risk of breakage  -  blind holes, hard materials, or close-tolerance threading  -  as the helical interpolation path allows easy size adjustment at the controller. Machinists and toolroom technicians working in aerospace, automotive, and general manufacturing will find this tool appropriate for both roughing and finishing internal threads in a single tool pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides oxidation resistance and extended tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e3-flute helical geometry generates smooth thread form with reduced radial cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle tool cuts M8x1.25 metric coarse internal threads via CNC helical interpolation\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies setup on machines without high-pressure coolant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CNC machining centers using helical interpolation cycles to produce M8x1.25 metric coarse internal threads.

Secure the shank in a balanced, properly torqued collet or end mill holder before spindle engagement. Verify CNC program thread interpolation parameters, including pitch and helical lead, match the M8x1.25 specification before cutting. Do not use in manual machines or attempt to drive with a drill press or hand tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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: 0.235 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 1.25 mm\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\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: 0.4 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 931-08125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743086969138,"sku":"931-08125","price":205.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e309e44da4c67b3796a9c0b7b86e02d9.jpg?v=1788842488","url":"https:\/\/voomisupply.com\/products\/accupro-931-08125-thread-mill-m8x1-25-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
