Rated 5 out of 5 by from Great Drill Had one of these for over 3 years and it drilled at least 24 holes. Those are the ones I remembered to account for. Gave up the ghost when I went through a preformed concrete slab wall without realising what it was made of. appeared to be rendered blockwork! Ripped the cutting blades clean off!! My fault really, no hesitation in buying another.

Stone walls?

OK, I guess brick and concrete is one thing But how does it perform on old stone cottage type wall?
Asked by: Linuxbox
The product would be capable of drilling old stone cottage walls, however, it may be necessary to take a little more time with the actual drilling. Drilling inside to outside is sometimes the better way to drill as due to the irregular shape of the stone it may be difficult to start the core off, the downside to this is that sometimes the finished hole can not be quite as neat due to the pressure being applied and the weaknesses within the stonework.

What arbor/adaptor/pilot drill do I need for this drill?

I have an sds adaptor with M22 male thread. Will this fit? What would be a suitable pilot drill (flat not tapered shank)? Is there a screwfix product to do the job? Thanks
Asked by: MifRdg
Hello, Unfortunately not. You will need an SDS to 1/2" BSP (M) adaptor for use with this core. The pilot drill will need to be A-Taper.

Which drill guide do I need to purchase for this Marcrist core drill

Having bought the core drill Marcrist 1849F I can't see which guide bit I need to purchase. It would need to be very long or require some kind of extension.
Asked by: SugarRay
Any standard, A taper 180mm long guide will be suitable however when drilling the speed of cut is only as good as the pilot you use.
