I will continue showing my naivety here!
I wanted to drill a 127mm hole in the wall for a kitchen extractor.
I bought an Erbauer Diamond Core Drill Bit 127mm to use with my Energer 850W Rotary hammer drill (ENB465DRH) along with 250mm arbor & pilot bit.
The problem is after drilling the pilot hole and starting to drill the hole, I can't get it to bite the brick. It's bouncing all over the place and making a mess.
Is it because the arbor is too long to start with and can't get stability so I should start with a 110mm arbor instead?
Is the drill not powerful enough and so not spinning fast enough?
I know these items are not the best quality but regardless, this shouldn't be happening should it?
I don't have it on any hammer action and it does have a clutch mechanism.
Am I supposed to push hard against the wall, unfortunately I have to stand on a ladder to do this so not the best position for leverage.
I did try putting this job in MyBuilder just to drill the hole but got no replies apart from one handyman who was going to chisel it out instead.
Thanks and hope you can help.
