Built from solid carbide and finished with OSG DUROREY coating, this tool delivers extended tool life and consistent thread quality in ferrous and non-ferrous materials. It features 6 flutes with a left-hand flute direction and left-hand thread direction, a cutting diameter of 3.10 mm, and a pitch of 0.70 mm for M4x0.7 metric thread production. The long-reach design provides access to deeper features. Coolant-through capability supports chip evacuation and thermal management at the cutting zone. This tool is intended for use by machinists and toolroom professionals operating CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThe OSG 8331201 is suited for M4x0.7 metric thread milling applications in production and job-shop CNC environments. Its long-reach configuration makes it appropriate for components where standard-length tools cannot access the thread zone. The coolant-through feature is particularly useful in blind-hole or deep-feature thread milling where chip packing is a concern. Left-hand thread and flute direction are critical specifications — confirm the required thread hand before ordering. This tool ships in individual packaging with a minimum order quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in thread milling operations\u003c\/li\u003e\n  \u003cli\u003eDUROREY coating extends tool life and improves surface finish in coated-carbide applications\u003c\/li\u003e\n  \u003cli\u003e6-flute design increases feed rate potential and improves finish compared to fewer-flute alternatives\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability aids chip evacuation and heat control at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eLeft-hand thread direction and left-hand helical flute geometry — verify hand requirement before use\u003c\/li\u003e\n  \u003cli\u003eLong-reach thread mill type for access to recessed or deep thread features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for M4x0.7 metric thread milling on CNC machining centers equipped with a 6.0 mm shank-compatible collet or toolholder.

Secure the 6.0 mm shank in a compatible precision collet or hydraulic toolholder and verify runout before cutting. Power down and lock out the machine spindle before changing or inspecting tooling per standard machine safeguarding practice. Confirm left-hand thread and flute direction match the programmed toolpath and workpiece requirement before beginning the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: DUROREY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 0.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3.10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 16640\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.95 inches L x 0.4 inches W x 0.35 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.315 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8331201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737586565426,"sku":"8331201","price":179.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8bfc02c43c6faaeffc5f0c82a7ee57dc_bfd8bcac-8df6-44ec-8257-a1b8094eaa91.jpg?v=1788790901","url":"https:\/\/voomisupply.com\/products\/osg-8331201-thread-mill-m4x0-7-metric-left-hand-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
