Crooks. I bought some of what Ideal world described as indestructible, drill anything never need to buy another drill piece again drill set. First drill i used was on a porcelain tile and it slid about everywhere so i went back to my 80p drill piece from toolstation. 2nd time was into brick which burnt out the end so i got the next size up which did the same. Ideal word expect me the customer to pay £5 to replace the knackered bits. Instead i have bought 2 from toolstation and had a nice fish and chips dinner. For less money. Ideal world refuse to give refund. Thieving b**tards no refund
