Needed to trim back the slates along the edge of the roof by an inch after removing the rendering on the wall below. Bought a Wickes 1000W
125mm AG, does the businness but it is eating stone cutting discs (non diamond). I bought three thinking that would be one and two spares...I'm about to use the last one. I've cut about six linear metres of approximately 5 mm thick roofing slate, mostly double with the some triple thickness. The lower layers I'm not cutting right through just making a score and snapping off.
Is that rate of disc use about right or am I doing something wrong?
