Toilet with silicon calcium plate ceiling, with the general opening device can not open, the kit is not work, is directly slippery, gear grinding, with alloy hole tool tool method can be resolved, the number is relatively large, the hole speed can be faster The best tool
Do not know how big you want to open, small can use alloy hole device
It is recommended that you build a drill bit yourself.
