  • IADC Classification System - Rock drill bits for well

    Metal drill bits are very expensive and arguably the most expensive of all the bits. You can not bore holes or cut through metals using the regular drill bits. The drill bits for metals are heavy duty and very hard. Two of the most recommended drill bits for metals are the Cobalt drill bits and the Titanium drill bits.
