Discuss wanted 45mm drill bit in the For-sale & wanted . at Plumbers Forums; I am after a large size drill bit :
pls let me know !
got sick of using a core bit for drilling waist pipe work...
Std sds fitting but only do up to just over 300mm. It will do a hole through a cavity wall in under a minute, go through wood and rebar. You don't need the pilot drill as they are easy to start. They last about 6 months or so until you loose the teeth of them or the extension bar snaps. Very little breakthrough.
diamond cores for me,down to 32, with water if hard, too much damage for me using tct or sds

It is easy to judge when you are nearly through with the small tct's. Take the hammer off for the last 10mm and there is little breakthrough or drill from outside in and at most you will need a small handful of plaster. SDS max bits and you will need a couple of brick to patch it sometimes.
My makita core drill (not sure what model, but has the variable speed on trigger) can put a 4 1/2" flue hole through an average cavity wall (concrete or brick, not thermalite!) in about 4-5 mins.... seriously I put it on hammer though, but its a very light hammer on this drill. You go through cores a little quicker, but not by much, but whats a core? £45? it's paid for itself if it saves you standing there with your head squashed against the ceiling kneeling on the kitchen worktop for half an hour!
