Thanks RC... I kinda figured out how to use, but wondering about durability.

Checked out the vid, however, said bugger all about brickwork and the ones didn't seem that strong. 

I want something for mounting powerboards, using a timber backing board on brick walls.  At the moment I drill a 4mm hole in the timber with a standard twist bit and then used it as a template to drill through the holes with a 4mm masonry bit to mark the brick and then the 6.5mm (or appropriatee sized bit) for the anchor. 
I am always looking for an easier way.

If your first cut is too short... Take the second cut from the longer end... LBD
