Review on 🔪 Cobalt Triangle Special Stainless: The Ultimate Power Tool for Precision Cutting by Mark Toth

I haven't had a chance to use any drill bits so I won't rate their durability or price. But what I think deserves credit is the set's promotional literature. This is incorrect. The ad states that all bits have a hexagonal (triangular) shank. Not so with my set. Only 9 out of 13 bits came with the advertised hex shank; The other four bits came with traditional round shanks.
