Hope Cryo Large Hook Tool 12mm tip.

12MM hook tool. 30% bigger size to the 10mm hook and designed for undercutting and hollow forms about 300-350mm deep with a medium handle fitted.

This tool will fit into a 13mm grub handle or the 13mm head on the quick release system.

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.

The end is machined to 12mm. This will fit into a quick release or grub screw handle of that size.

Or it will fit into the hollowing rig with the 10mm collet. Available on the hollowing rig page.
