12mm Hook Tool with sharpening mandrel
Designed to get into hollow forms for under cutting and cleaning up.
The HSS 12mm tip is made from cryo HSS and keeps its edge for a long time.
The tool comes with a torx key and round bar tip holder for sharpening the tip.
Simply screw the tip on the holder and then sharpen in a battery drill on a diamond file.
Avoid a grinder as this would shorten its life by grinding too much away.
