Review on 🔩 Driak Titanium Coated Materials Drilling: Enhanced Precision and Durability by Bart Elbrink

So far I've cut several 2" holes in 1/4" aluminum and steel siding. It takes a while to drill through aluminum with a power drill, but with patience I can make smooth, round holes. .In thin steel with a hand drill he suddenly grabs and pulls deep so hold on tight and go slow. A quick bite deforms the steel at the edge of the hole. I can't even begin to estimate how long this will stay sharp, and I highly doubt it could be sharpened for less than its $25 purchase price. The holes I need in aluminum would cost a lot more in a machine shop and it still has a lifespan so I think the value is great. Compare this to the costs of your projects and decide for yourself.
