This is the premium method. The drill bit is ground from a single solid blank of hardened steel using CNC machines³.

• Roll Forged: Steel is heated and rolled to form flutes. Retains grain structure, making the bit elastic and resistant to breaking.
• Best For: High-volume wholesale orders, economy drill bit sets.
