This little drill bit is a powerhouse! It sliced through hardened steel like butter and the finish is still flawless after multiple jobs. Fantastic durability.
Precise, clean holes every time in tough materials. The chrome finish seems to reduce friction and heat build-up. Worth every penny for professional results.
Exceeded my expectations for such a small diameter bit. The tungsten carbide tip shows no wear after extensive use on metal and tile. Bosch quality is consistently reliable.
