Review on π© Premium Stainless Steel Cobalt Drill Bit Set: Ultimate Tool for Precision Drilling by Gervan Mauldin
It is very good! - Power Tool Parts & Accessories
I used one of these drill bits to drill through the cast iron lid to attach two handles to attach the flat top cast iron grill lid. The drill went through the cast iron like cardboard. These bits are very reliable and you will be satisfied with this purchase.
Pros
- Power Tools & Hand Tools
Cons
- There are nuances
