12mmHK
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.
This tool fits into a medium grub or quick release handle systems.
