Review on 🔨 SP Air Corp SP-7212 Heavy-Duty by David Dober

I was dying to get this tool but the collet took Superman's hands to loosen and after it loosened the bit was still sticking out and had to be knocked out with a hammer or pulled with a vise. The special wrenches that came with the grinder were too short to have any real leverage to loosen the collet nut.
