However, RDMT1204MO has a thickness of 4.76mm (0.187\"), providing extra strength for heavy-duty roughing, while RDMT12T3MO has a thickness of 3.97mm (0.156\"), designed for cutter bodies with T3 pocket dimensions.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"lamina-faq-item\"\u003e\n\u003cdiv class=\"lamina-faq-q\"\u003eQ2: What is the difference between RDMT and RPMT inserts?\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cem\u003eAnswer:\u003c\/em\u003e The second letter denotes clearance angle. RDMT inserts feature a 15° positive clearance angle (D clearance), whereas RPMT inserts feature an 11° clearance angle (P clearance).
