"Purchsed this item as it was far cheaper tham other stores. So for the price you would expect an inferior item. However i have drilled 4 holes through 2 layers of solid brick each and the drill bit looks like it can do a lot more drilling. Overall a fantastic item for a very low price. Very Pleased."
"This drill bit is perfect for passing 20mm round conduit through a double skin cavity wall. I needed 3 holes for TV / Satellite cabling and low voltage decking lights / water features powered from indoor transformers. The drill performed well, with smooth clean bore holes and a perfect snug fit for the lengths of conduit. (Drill a pilot hole first). The indented mount means it will fit a standard 13mm chuck, which is a good feature. Definitely one of my better purchases."
"Bought this to install CCTV, It really did struggle to go through the outer layer of block, but I think that they are made of flint and pebbles. Once through to the inner skin (Standard *Breeze* block) it went through in seconds.
Nothing in the catalogue to say so but it fits a standard 13mm chuck."
