It carries an 80-degree diamond insert shape with a neutral hand orientation and a negative rake geometry, making it suitable for general-purpose roughing and finishing passes. The TT8105B grade features a multilayer CVD coating  -  TiCN, Al2O3, and TiN  -  applied over a carbide substrate to deliver wear resistance and thermal stability at elevated cutting speeds. Licensed HVAC and industrial cutting tool technicians or machinists handling CNC lathe work will install this insert into compatible CNMG-style toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert fits CNC turning centers and manual lathes equipped with CNMG-style clamp-type toolholders. Its primary application is steel cutting, including carbon steels, alloy steels, and similar ferrous materials identified under ISO material group P. The PC chip breaker geometry supports controlled chip evacuation during continuous turning cuts. With a maximum depth of cut of 0.256 inches and four available cutting edges per insert, it is suited to medium-to-heavy stock removal as well as light finishing work on steel components. The ISO designation for this insert is CNMG160612PC TT8105B.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiN for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003ePC chip breaker geometry for controlled chip evacuation on steel\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tool life and lower per-edge cost\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with standard CNMG toolholders\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry supports stable cutting at higher feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style clamp-type toolholders accepting inserts with a 5\/8-inch inscribed circle, 1\/4-inch thickness, and 80-degree diamond geometry.

Power down and de-energize the machine before changing inserts. Seat the insert fully against the toolholder pocket locating surfaces before tightening the clamp screw; an incomplete seat can cause premature edge failure or dimensional deviation. Rotate to a fresh cutting edge when wear patterns develop rather than running an edge to failure, which risks workpiece damage and toolholder wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT8105B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.250 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.256 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 543\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160612PC TT8105B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6212812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51971539599666,"sku":"6212812","price":362.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b889264a7047778d5b0648107c14f4fa_b380521b-3c93-4aee-97f8-071439cad1b2.jpg?v=1789958265","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6212812-turning-insert-cnmg543pc","provider":"Voomi Supply","version":"1.0","type":"link"}
