Should be easy, done it many times in all sorts of bricks, blocks and concrete. Using hammer drill (if required) and decent bits, take it slowly, clear often.
However recently moved to an old terrace, brick built with nasty soft, gritty grey plaster. I find one in two holes drilled so far fails, bit skids or bounces. I have tried both Wilko bits and de Walt bits. Both bounce, skid or simply overheat despite due care. I feel like a fool, whatever can be going wrong? Yup, it is NOT set in reverse ...
Are these local bricks made of some special hard grade firing or are these bits just crap? I must have drilled many hundreds of holes in bricks and concrete and even granite before. Thus has got me beat andfoir the first time in forty years of day, joining a forum for ideas and recommendations for drill bits, 5.5 to 8mm!
