Built from micrograin solid carbide and coated with TiAlN, it delivers consistent thread quality and extended tool life in production environments. The 4-flute geometry and right-hand flute direction support efficient chip evacuation during internal threading operations. With a cutting diameter of 0.3 inches and a 0.75 inch length of cut, this tool is suited for CNC machining centers where precise thread milling is required. Licensed machinists and CNC programmers working in metalworking, mold making, and general manufacturing will find it a reliable choice for metric thread applications.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is applied in internal threading operations on CNC machining centers. It is sized for M10 threaded holes with a minimum nominal diameter of 0.3937 inches. The 5\/16 inch shank diameter fits standard ER and side-lock toolholders common in vertical and horizontal machining centers. Typical applications include threading in hardened or difficult-to-machine materials where a tap would risk breakage. The TiAlN coating provides heat resistance suitable for dry or minimal-lubrication cutting strategies in steel, stainless, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating provides elevated heat resistance for dry and semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute helical design promotes chip evacuation during internal threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle-tool solution for M10x1.5 metric coarse internal threads\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers as an OEM-style thread mill for M10x1.5 metric coarse internal threading applications with a 5\/16 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by a qualified CNC machinist or tooling technician. Secure the 5\/16 inch shank in a properly sized collet or toolholder and verify runout before cutting. Program the helical interpolation cycle according to the machine control and tooling manufacturer guidelines for thread milling. Confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M10x1.5\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3 inches (7.62 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (8.00 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\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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: 931-10150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742266917170,"sku":"931-10150","price":274.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c744cdca8aca76b1a856341a49d2a651.jpg?v=1788836325","url":"https:\/\/voomisupply.com\/products\/accupro-931-10150-internal-thread-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
