It is designed for use in indexable milling cutters and delivers high-speed metal removal across a broad range of workpiece materials. The insert features a TiAlN coating applied via PVD process, which provides thermal resistance and wear protection at elevated cutting temperatures. With 8 cutting edges on a double-sided configuration and a negative rake geometry, this insert is built for high-productivity face and shoulder milling operations. Licensed HVAC, plumbing, and cutting-tool technicians and machinists specify this insert for demanding production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, cast iron, hard materials, and superalloys including titanium  -  material application codes P, M, K, H, and S. It is compatible with the THSN12 cutter series and is held in place via screw clamping. The MM chip breaker geometry is optimized for controlled chip evacuation across these material groups. Typical applications include face milling, shoulder milling, and general-purpose indexable milling in both light and heavy production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-sided insert with 8 cutting edges for maximum edge economy\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating via PVD process for thermal wear resistance at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 90-degree included angle square geometry for stable, rigid cutting\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker for effective chip control across steel, stainless, and cast iron\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for improved edge integrity and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eCompatible with THSN12 cutter series; insert held by screw clamp method\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the THSN12 cutter series.

Disengage and lock out machine spindle power before indexing or replacing inserts. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specification  -  do not overtighten. Inspect the insert pocket for chips or debris before seating the insert to ensure full, flat contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMU\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH3135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 12.00 mm \/ 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 7.50 mm \/ 0.2950 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm \/ 0.0315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 9.50 mm \/ 0.3740 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30, M30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: THSN12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6780139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972086399282,"sku":"6780139","price":44.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc1c52e8e53ccc1ef66567d2fc7f199c.jpg?v=1789962262","url":"https:\/\/voomisupply.com\/products\/tungaloy-6780139-milling-insert-snmu120608hnen-mm-ah3135","provider":"Voomi Supply","version":"1.0","type":"link"}
