Review on 🔩 1877793 IRWIN Metal Countersink Drill by Bill Russett

I've been using these for a few weeks now and for the price they work great. I deducted 1 star from them because they needed sharpening right out of the box (the holes became hexagonal). But after a short sharpening, they run great. Tried them through plywood, softwood and hardwood. I haven't tried metal yet. Ideal if you don't want to spend a lot of money.
