Are Harbor Freight Cobalt Drill Bits Actually Amazing?

Reddit said that this cobalt drill bit set sucks, but I wanted to test it myself. This is a Harbor Freight, Warrior-brand, 115 piece complete index of cobalt drill bits.

If you're curious about the durability and performance of these cheap cobalt drill bits on different materials like steel, aluminum, and brass, you’re in the right place. I tested these cobalt drill bits with my Grizzly G0602 lathe, and with my Precision Matthews PM-25 milling machine that I converted into a CNC mill.

Whether you’re looking for affordable drill bits for metalworking or a versatile and complete drill bit index for DIY projects, I’ve got you covered. I will show you how these bits hold up against tough metal and softer materials, and compare them to other cobalt drill bit sets on the market - two cobalt drill sets from Bosch and one cobalt set from Milwaukee - and I'll explain why I purchased these Harbor Freight drill bits instead. Are they a budget-friendly option for your workshop? Let’s find out!
