"For drilling hard brick I usually go for Dewalt bits, however there were none in stock the size I wanted so I ended up buying an Erbaur (cheap screwfix own brand). I regretted this purchase as the bit had a melt down after the third hole. I went back and replaced it for a Bosch and many holes later is still looking and working like new. Not a bad price either for the 210mm. I will probably stick with the Bosch from now on."
