long bit. I wouldn't want to bore you.
Needed a SDS masonry bit to drill a hole through cavity wall (UK cavity 100+50+100mm+render&plaster) at 310mm long this one was just right to do the job, not too long. No problem through concrete blocks and made a good accurate 10mm hole. This Duratool did the job well and at a good price.
