Ive been using black and decker drills for over 25 yearsthis seems to be the worstburrnt out at least two drills drilling into the brick shed wallseems to rev excessively fast while at the same time hammering ineffectivelyalso the chuck is the worst keyless chuck i have ever used apart from one on an old bosch

The bit came loose at least three times in the first few minutes of use and i am very very experienced using power tools and the chuck was fastened as per instriuctionsalso the chuck clutch button is small and poorly located at 6 oclock
