The insert is manufactured from solid carbide and carries a CVD-applied TiCN plus TiN coating for wear resistance and extended tool life. It features a 60-degree triangular shape with a neutral hand orientation, providing six usable cutting edges per insert. The QM chip breaker geometry is suited to medium machining conditions. With a 3\/8-inch inscribed circle and a 1\/64-inch corner radius, this insert fits standard TNMG toolholders used by machinists and CNC turning professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 5753988 is primarily applied to turning steel workpieces and performs as a secondary grade on stainless steel. It is a solid choice for medium-depth roughing and semi-finishing passes where chip control and coating durability are priorities. The T-Max P series is a widely used platform in production turning, and the QM geometry is specifically designed to manage chip flow in steel and stainless steel applications. Installation requires a compatible TNMG-style toolholder using either a clamp or pin holding method. Typical users are CNC machinists and tool-and-die professionals working in metalworking and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-applied TiCN and TiN dual-layer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eSix usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eQM chip breaker geometry optimized for steel and stainless steel turning\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard TNMG toolholder setups\u003c\/li\u003e\n  \u003cli\u003e1\/64-inch corner radius suitable for medium finishing and semi-roughing passes\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method compatibility for secure insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard TNMG-style toolholders that accept the clamp or pin holding method.

Use the correct torque wrench and clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the insert pocket and seating surface for debris or wear before seating a new insert. Never force an insert into a pocket that does not accept it freely, as this can cause insert fracture or toolholder damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 235\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: TiCN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: QM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6338 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\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\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code 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\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG 16 03 04-QM 235\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5753988\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51738843250994,"sku":"5753988","price":259.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c7d1e3ca782853b8703a257f38473aa.jpg?v=1788805409","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5753988-tnmg321-qm-235-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
