It worked well as expected

I needed to drill some holes in a 3mm-thick steel plate. It was super easy and fast with this drilling bit. I used a metal screw to punch a small mark at the drilling position first before I started drilling.

Pros

For the price you can’t go wrong

Cons

The drill bit may be too expensive for some users, making it an impractical purchase

Worked OK to drill through 6062 aluminum. Didn''t drill a lot of holes but enough to know at least it''s not a garbage drill like some.
