Review on Bosch HTCTCP Carbide Tipped Hole Pilot: Precision Drilling Made Easy by Steve Hauck

This is the only bit available that works with Bosch TCHS drill bits which require a 7" quick change Bosch pilot bit. It has a wall top and works. Works well with most materials but wood is slow to cut and I had to remove the drill bit from the mandrel and then remove the pilot cutter to get the plug out after cutting the hole which slows it down even more. Good concept but not the best execution.
