This 20mm Gripit Undercutting Tool is specifically designed for use with 20mm Brown Gripit Plasterboard Fixings, making it the ideal choice for heavier-duty applications requiring increased holding capacity. The 20mm diameter creates a generously sized recess that ensures the fixing wings can open completely and grip securely behind the plasterboard. Simply attach this undercutting tool to any power drill for quick and efficient operation.
It expertly removes insulating fibre from within the cavity, preventing entanglement issues that could compromise fixing performance. Whether you're installing on dot and dab walls, working with double thickness plasterboard, or tackling insulated wall systems, this tool delivers professional results with every use.
