Review on π§ Top-Notch Performance: Bosch CO2159 Cobalt Drill Bit for Ultimate Precision by Eric Mueller
Great value drill bit that handles hardened steel with ease
Oil handles it all with no problems. Just note that as this is a 1/2 inch drill bit you will need a drill bit that fits this size drill bit.
Pros
- Hardened surface for penetrating hard, abrasive materials
Cons
- Not as thick as other screwdrivers
