Buying Guide
Drilling high nickel alloys needs tough tools. Regular bits wear fast or break. Users love cobalt inserts with TiN/TiAIN coatings—they cut clean and last longer. Heat resistance and quick swaps make jobs easier.
- Material: Cobalt steel stands up to heat and pressure. It’s stronger than regular steel for tough alloys.
