If you need to mill hard and abrasive materials such as cast iron or stainless steel, look no further than our carbide corner radius end mills. With a durable AlTiN coating that withstands high heat and wear better than TiN, TiCN, and TiAlN coatings, these end mills are built to last. The square nose and slightly rounded corners create a balanced cutting action and distribute forces evenly, preventing damage to the end mill and providing exceptional performance. Our corner-radius end mills also offer excellent wear resistance and heat resistance, making them superior to high-speed steel, cobalt, or powdered-metal alternatives. These versatile tools are ideal for general machining applications but should not be used on hard materials such as titanium or gummy materials like aluminum. Perfect for creating flat-bottomed grooves with rounded inside corners, our corner-radius end mills come in a variety of sizes and can tackle a range of projects. Upgrade your machining process and see the difference for yourself!
