Review on Self-Centering Adjustable Tenghebao Woodworking Autocenter by David Silva

later. As another reviewer recently wrote, these will work as intended and appropriately. There is almost no bevel on the guide to help align it in a loop or threaded hole for more precise drilling. The materials seem cheap, but again sufficient. The box they came in was broken upon delivery, although the shipping box was well stocked with Revain, so the broken plastic box was probably from the original assembly. The parts were supposed to be separated in a foam cutout, but the cutout was so flimsy and cheap that it was crushed and unusable. They are useful for my simple woodworking and hobbies.
