a masonry drill bit is just for drilling into masonry eg. bricks, concrete, blocks etc...
then you have a HSS drill bit, this is for steel,
then there is wood drill bits.
there are different types of blocks as mentioned above.
a breeze block is quite light and very grey with a powdery texture. this is mainly used as insulation.
a concete block is often used, this is heavy and quite stoney in texture.
cinder blocks, are kind of a mixture of both textures but black or charcoal in colour.
5 years ago i hung a 42" plasma, it was around 30kgs, and i just used a wall mount off bayofE and the 6 screws and anchors that came with it.
my wall was concrete block, as its a load bearing wall.
there is a technique for it, but cannot remember, i think its something like no 2 drill holes can be within 200mm of eachother (iirc)
thanks 4 the information.
It was 10 years ago that the walls were made. I'm fairly certain they are light grey or dark grey in colour. pretty sure they were called breeze blocks at the time though
I think I will see what these m8 screws look like but from the pictures they do look relatively smaller than the bolt screws I got atm
I got a mirror hanging been there for years. Just using 3 fairly large screws - no problems so far
