Review on 💪 Efficient Cutting with Greenlee 625 7 Carbide Tipped Cutter - 8 Inch by Will Rahman

I bought this drill bit and only drilled 10 holes in 1/8" steel and found that 3 out of 4 carbide tips were torn out. another hole and the fourth was gone. They sent me a replacement. The first hole I drilled in the same steel ripped out 2 carbides. Then I was able to drill 25 more holes with 2 carbides remaining. Slightly slower speed and less pressure. No more carbides in the hole by the 26th This one was put in a 490rpm drill and lubricated the entire time This cutter feels like a cheap knockoff from China.
