Hi I need to use a 70mm hole saw to put in 60 soffit vents,the problem i have is i cannot get in to do the job with my normal drill so can anyone tell me are these angle drill attachments capable of doing this job because i heard they dont last for long.also will cordless 14 v angle drill be good enough to do this job. p.s.will have to cut through upc and plywood total thickness of 15mm.
cheers Tom.
