It is engineered for high-performance milling operations where tool life and edge stability are critical. The insert features a Physical Vapor Deposition (PVD) AlTiN coating that resists heat and abrasion at elevated cutting speeds. With a positive rake geometry and a right-hand cutting orientation, the 189958 promotes efficient chip evacuation and reduced cutting forces. It is sized at insert code 0934, with a cutting edge effective length of 0.358 inches and a thickness of 0.134 inches. Licensed machinists and tooling specialists install this insert on compatible milling toolholders secured by screw clamping.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling applications across a range of workpiece materials, including cast iron, stainless steel, and steel as primary targets, and hard materials, superalloys, and titanium as secondary applications. It performs in both roughing and semi-finishing passes where the M2 chip breaker geometry helps manage chip flow across varying feeds and depths of cut. Typical use environments include precision machining shops, production milling cells, and maintenance machining operations requiring a reliable indexable carbide insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVP15TF grade solid carbide construction with PVD AlTiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003eM2 chip breaker geometry supports controlled chip flow across multiple material types\u003c\/li\u003e\n  \u003cli\u003ePositive rake design reduces cutting forces and heat generation at the edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation with screw-in insert holding method for secure seating\u003c\/li\u003e\n  \u003cli\u003eEffective cutting edge length of 0.358 inches and 1\/32-inch corner radius for accurate profiling\u003c\/li\u003e\n  \u003cli\u003eISO-standardized QOMT0934R-M2 designation for straightforward cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for QOMT-series milling toolholders accepting QOMT0934R-M2 inserts per ISO standards.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key specified by the toolholder manufacturer when tightening the clamping screw to avoid insert cracking or improper seating. Inspect the insert pocket and seating surface for debris or wear before fitting a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: QOMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: QOMT0934R-M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: VP15TF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\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\u003eChip Breaker\u003c\/strong\u003e: M2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 0934\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.358 inches (9.09 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.134 inches (3.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.031 inches \/ 0.79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1161 inches (0.12 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: MITSUBISHI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 189958\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITSUBISHI ELECTRIC","offers":[{"title":"Default Title","offer_id":51692999639346,"sku":"189958","price":255.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/edab8d3c4802c00999cf0c46ca7a251d.jpg?v=1788306025","url":"https:\/\/voomisupply.com\/products\/mitsubishi-189958-milling-insert-qomt0934r-m2-vp15tf","provider":"Voomi Supply","version":"1.0","type":"link"}
