### ⭐⭐⭐⭐⭐ FIFTH COMPNY WAS THE CHARM , HAPPILY GOT ER DONE
*by D***R on August 20, 2025*

I tried 5 different Cobalt bits. Ordered from 3 different companies. They weren't sharp. Sent them back. Took a chance and ordered from a 4th company with good reviews for sharpness. A gain the bits were not sharp. Dent them back. Thought I would give it one more fifth try from this company. HURRAH !! Opened the package , took a bit out and tried it. IT DRILLED THE HOLE IN MILD STEEL ALMOST LIKE BUTTER. THEN DRILLED 2 MORE HOLES WITH THE SAME BIT. NO PROBLEMS DRILLED THEM EASILY. WOULD DEFINATELY RECOMEND THESE BITS. ARRIVED IN ONE DAY. VERY SATISFIED.
