Review on π© Cobalt Drill Bit by Bosch: CO2151 by Julian Perkins
Works well with 7075-T6 aluminum
Simply poked through this strong aluminum with no tension, however the metal stuck to the bit until the coating wore off, after which it continued to work smoothly. I don't think the coating helped, but the bit is still as sharp as a blade after 20 1.5" dives without cutting lube. Normally I would lube, but aluminum conducts heat so well it's not really necessary. Definitely Bosch quality.
Pros
- Twist drill
Cons
- Requires socket
