I'm new to drilling but I've read up as much as I can.
I need to drill some 8mm holes in brick (not the mortar) for 8mm rawlplugs.
I'll be using a 550W Bosch corded hammer drill and I have a set of masonry bits at 3mm, 4mm, 5mm, 6mm and 8mm (they are hex shank, I chose that because in several reviews of the drill people were complaining about it losing grip - it's a keyless chuck with 3 jaws).
I have a center punch to mark the initial drilling point.
Suggestions for sensible pilot hole size? (The rawlplugs are 8x32 so I was planning to go around ~40mm deep for the final hole).
Also is a good idea at the very beginning not to use hammer mode, to get the hole position correct?
I'm guessing in some situations people might drill more than one pilot hole, but maybe not for a hole this small? (Thanks)
