Conclusion

The best drill bits for drilling steel are those that are made of high-speed steel or tungsten carbide. These drill bits are able to withstand the high temperatures that are generated when drilling into steel.

They are also able to maintain a sharp edge for a longer period of time than other types of drill bits.
