Review on 🔧 Rocaris Speed Steel Drill Stainless: Unleash the Power of Precision and Durability by Scott King

This item I received a few hours ago is already broken, the bits cut well. But the mandrel broke in half on the 3rd hole at 300rpm and light pressure. The supplied Allen key is also the wrong size; The first thing I did while pressing on the center pilot was remove the set screw. Come to find out the wrong Allen key size. The chisel jumped off the mandrel: the chisel had to be welded to the mandrel. One more thing, the little spring in the middle will get stuck and prevent the bit from penetrating the material, pull the spring off. The Revains seller should refund my money
