What are carbide tips? | HowSfWorks

Carbide tips do get dull eventually. You sharpen them using the same techniques you would use with tool steel, but because they are so hard, you use a different abrasive. Something coated in diamond or a carbide abrasive wheel is common. If you''ve read How Diamonds Work, you know that diamond (pure crystalline carbon) is the hardest material there is.
