A2™ • Single-Ended Cut-Off

If your machining operations depend on accurate single-ended cut-off tools, you can immediately improve your processes with A2 cut-off tools. These solid carbide tools are optimal for high-speed applications with cast iron, non-ferrous metals, and other tough workpiece materials. When you use cut-off tools from Kennametal's A2 line, you achieve consistency while reducing downtime with inferior tools. If you have questions about our A2 line or need a specialty tool, our design team is ready to assist.
