Carrying the AH905 manufacturer grade with a PVD-applied AlTiN coating, this insert targets superalloys and titanium as its primary workpiece materials  -  among the most challenging categories in production machining. The 80-degree diamond shape (Insert Shape Code C) provides a strong cutting geometry, while the HMM chip breaker and chamfered-and-honed cutting edge style support stable chip control and edge protection during turning, facing, and boring operations. The insert measures 0.508 inches in length with a 0.5 inscribed circle and a 0.0315-inch corner radius.\u003c\/p\u003e\u003cp\u003eThis insert is suited for CNC turning centers and manual lathes where superalloy and titanium components require consistent, repeatable stock removal. The neutral hand orientation makes it adaptable across multiple toolholder setups. With four cutting edges available per insert, it delivers extended tool life value per unit. Typical applications include turning, facing, and boring on aerospace, medical, and energy-sector components where workpiece materials such as Inconel, titanium alloys, and other high-temperature alloys are common. It conforms to both ANSI and ISO standards under the industry number CNMG 432 HMM.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAH905 grade with PVD AlTiN coating optimized for superalloys and titanium (Material Grade S01, S10)\u003c\/li\u003e\n\u003cli\u003eHMM chip breaker geometry with chamfered and honed cutting edge for stable chip control\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with negative rake angle (-15 degrees) for strong edge support\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for extended per-unit tool life\u003c\/li\u003e\n\u003cli\u003eMulti-use application: turning, facing, and boring from a single insert\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in standard CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to fit standard CNMG toolholders accepting a 432-size insert with clamp and pin holding.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and confirm the clamp and pin are properly engaged before resuming cuts. Do not exceed the maximum depth of cut of 0.1181 inches without confirming the toolholder and workpiece setup can handle the resulting cutting forces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG432HMM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AH905\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HMM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative (-15 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.203 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1181 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\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 and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 6859436\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972052648242,"sku":"6859436","price":217.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3703b0c940149dc7be0f181bbea94e05.jpg?v=1789962084","url":"https:\/\/voomisupply.com\/products\/tungaloy-6859436-cnmg432hmm-ah905-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
