Single handed operation, pull the outer sleeve back, take out the bit, insert a new bit and pull the sleeve forward, it's that simple. The bit is firmly retained and the holder is fitted with a strong permanent magnet. As bit holders go this is top of the pile.

Cracking piece of kitI bought this over two and half years ago and its had a real hammering in that time, its in constant use and its only recently started showing signs of wear by holding onto the bit and I have to use a little force to remove it. I have abused it by driving screws without pilot holes well into the timber. I've used it on removing tight stubborn screws in masonry, in metal struts and driving into concrete.
