Rated 5 out of 5 by from Gripit cutter Very useful tool when the plasterboard panel is dab fixed to solid wall allowing grip it 'wings' to open

Rated 5 out of 5 by from Does what it says! My first foray into the world of Gripits saw my plasterboard holes go flush up to a steel lintel. A second trip to Screwfix furnished me with the undercutting tool which neatly routed an undercut to the hole, flush with the face of the lintel to allow the Gripit wings to expand. Product worked well with some care, just a shame that it is so expensive and only works with the one size of Gripit

Rated 5 out of 5 by from Essential Piece of Kit Bought this along with Gripits just in case there was a need to 'clear out' on the other side of the plasterboard so that wings would open correctly. Ended up using it on every hole to remove obstructing material. Easy to use and control. Easy to adjust to various thickness of plasterboard. Essential piece of kit when using Gripits.
