The ability to withstand heat means that cobalt bits perform for long periods without cooling or the need for cutting fluid. They are most often used to cut through hardened and abrasive materials. Cobalt bits are able to cut through the most hardened metals, including bronze, cast iron, stainless steel and titanium.
Application: Able to cut through the most hardened metals, including bronze, cast iron, stainless steel and titanium.
Units: 1 Unit
Features & Benefits: The 5-8% of cobalt element in cobalt drill bits gives it additional strength and more durability. It's effective against hard metals, stainless steels, and cast irons, which gives it an advantage over high-speed steel. It offers more wear resistance and works optimally at higher temperatures than HSS. It requires a smaller flute that hardly snaps during use and produces a better effect than HSS drill bits.
