Review on 🔧 Bosch AutoStart Carbide Mandrel with HDGQA for Enhanced Performance by Knate Scarpelli

Typical Bosch tool, this tool is well made and I needed it for the stone hole saw I use. The only problem I had was that the pilot point was not filmed. After the initial start of drilling, it would be advantageous to remove the pilot head as it cannot drill without grooves. This meant that in order to advance the hole saw further than the retracted point, I had to use a drill to poke a hole through the stone, through the center of the core I was trying to remove. This was an extra step that would not have been necessary if the guide point could be removed, as is possible on most hole saws I know of.
