Review on Efficiently Cut Aluminum and 🔪 Copper with Uxcell Bi Metal Cutting Tool by Chef Buntiloy

I have other hole saws (red) from other manufacturers and they do at least 15-20 holes in the material that I drilled This drill bit was only enough for one hole, I ended up having to make a fixture and use a router to cut the remaining 29 holes. Delivery was quick but the quality was disappointing.
