Have searched for the original lock n load masonary bits for ages to no avail. Irwin made them for a while and cannot find them for love nor money. These masonary bits drill through wood and masonary in one go so no need to change from one bit to another. Have always fixed skirtings to walls with screws and these bits do the job effortlessly. The Quick change chuck shank is larger than the usual size you get from other makes which I have had break on numerous occasions. Cannot rate this product highly enough. Superb quality without a doubt.
