Review on Jobber Carbide Tipped Standard 50362 by Darrin Lucas

These drills are second to none! I've used them in a cordless hand drill for drilling holes in mild steel! This drill bit cuts steel like butter! I will be buying more of these super drills soon. Some people have trouble with these drill bits because they don't understand how to use carbide cutting tools. Carbide drill bits work best on CNC machines but can be used in hand drills if you are careful and understand that carbide is inherently brittle and like to work at high speeds and feeds. Carbide drills do not like interrupted cuts. Use them properly and they will last a very long time. I love these carbide drill bits and would like to purchase a full set from Superdrill USA. Thank you for making such a great product. Arnie Kwiatkowski, locksmith from Dorr Michigan.
