This nibbler cuts sheet metal without distortion to the panel. Fitted to an electric or air drill it can be used to cut straight or curved shapes even from the centre of a panel, ideal for cutting holes for sunroofs or letting in bonnet louvers. The nibbling action removes 3.5mm (1/8”) chips to leave burr free edges. Cuts a maximum of 2mm (14swg) aluminium, 1.5mm (16swg) mild steel, 1mm (20swg) stainless steel.
