The only wood-drilling spade bits B&Q seem to sell now is new threaded ones (can't remember the manufacturer). The pointed end is threaded and the pack says (quicker cutting blah blah). They are useless. The thread pulls the bit into the wood so rapidly and in a totally uncontrolled way, where it promptly gets jammed and tears up the wood before yanking the drill out of your hands. Who ever designed these clearly tested them only on cheese. Very strange. Simon.
