Rated 4 out of 5 by from Cheap and reliable Good quality, affordable price. Recently drilled some brickwork with metal inserts, it came through, the core is intact, so yes go for it!

Rated 2 out of 5 by from Only good for soft materials It's fine for breeze block, soft bricks, soft render, or fly ash blocks. But as soon as you ask it to cut anything harder, it's just not up to it. I only bought this one as I was working far from home and I didnt have a 117mm core cutter with me, the Marcrist ones were out of stock that day, and I bought this one to get me out of trouble. I first cut 6 holes through breeze blocks, one after another, all fine. Then I just about managed to get 2 holes through standard cavity brickwork consisting of London yellow stocks on the outside and class b engineering bricks on the inside. This was with a dewalt core drill, correct speed setting, extractor unit, and without hitting any wall ties or rebar etc. For the 2nd hole, I was having to chain drill it first. After that, this core cutter was only fit for recycling unfortunately. To be fair - you get what you pay for.

Rated 1 out of 5 by from No no no Went through the breeze block ok. I got about 1/3 of the way though the outer brick skin and it just stopped cutting. The bit itself looked fine but it was just rubbing the brick and not cutting at all.

Rated 4 out of 5 by from Did the job at a good price I bought this to drill two holes through a 16 inch stone wall and also two holes through a single leaf brick wall. The job took about 30 minutes in total and there was very little wear to the bit. It may not last as long as those core bits costing three times as much but it did the job! Reliability difficult to rate after 30 minutes use....

Can I use this to drill through an external brick wall to fit a vent?

Asked by: Uves
Hello Uves, This could be used to drill through a brick wall but the bit is only 150mm in length so the thickness of the wall would determine if it would work. Thankyou for using Q&A

What arbor bit size is compatible with this?

Asked by: vinny888

Is there a central drill bit for this to hold it steady?

Can it be used for cutting 20mm porcelain?

And would be enough to cut a total for 7 holes?
Asked by: MozySh
Hello MozySh, Unfortunately this is not suitable for drilling porcelain. You will require a tile drill, but unfortunately we do not stock them in this diameter. Thank you for using Screwfix Q&A.

Do you need a special drill for this or will a normal DIY electric drill do the job? do you need an adapter?

Asked by: 2hard
Hello 2hard, This should be used with an Adaptor and a heavy duty drill like an SDS drill. A normal combi drill won't be powerful enough. Thank you for using Q&A
