Review on 🛠️ LETON HSS Cobalt Drill Pack: Power through Any Material with Precision by Jason Cho

The packaging is poor, all parts are taken out of the boxes and hanging in the envelope. Bit life was less than 1/6 inch when using cutting fluid. This is not HSS! I ended up using an old and real HSS bit that I found in my old editing toolbox and it dates back to the 90's. This drill bit made 3/4" thick steel that I had to drill through. I think I should dig first before buying this junk. Never waste your money again unless you're drilling in soft metal.
