WizeBuyz Take
When it comes to drilling hard metals, the Milwaukee 48-89-2329 1/2-Inch Thunderbolt Cobalt Drill Bit is an excellent choice. It's designed for extreme durability and long life, with a thicker core that protects against side-load breakage and a parabolic flute form that clears chips and debris fast for a cool bit. The precision start split point ensures fast and accurate holes, while the 3-flat secure grip shank reduces bit slipping in the chuck. However, some users have experienced the bit going blunt and proving useless after a short period, and some consider it overpriced compared to other brands.
