YBD151 is better for continuous, high-speed finishing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 20px; background: white; padding: 20px; border-radius: 6px; box-shadow: 0 2px 4px rgba(0,0,0,0.05);\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 5px;\"\u003eQ: Is the PM chipbreaker suitable for heavy roughing?\u003c\/p\u003e\n\u003cp style=\"font-size: 14px; margin: 0;\"\u003eA: No, the PM chipbreaker is designed for medium-to-finishing operations. For heavy roughing, we recommend a DR or flatter geometry to maintain edge strength.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background: white; padding: 20px; border-radius: 6px; box-shadow: 0 2px 4px rgba(0,0,0,0.05);\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 5px;\"\u003eQ: Can these be used for steel?\u003c\/p\u003e\n\u003cp style=\"font-size: 14px; margin: 0;\"\u003eA: While they can cut steel, the YBD coating is optimized specifically for the abrasive nature of cast iron.
