rubi angle grinder corers

[kilty55]

any thoughts on these corers guys/gals..i bought one today and used on half a dozen porcelain holes so far very good and a really good price as well

I've thought about getting a set from ATS, but haven't bothered yet. How clean are the holes and how many do you think you'd get per bit?

I tried some rubi ones recently and purchased a 20mm bit. Yet to use it in anger though!

Yup, we do them. We've converted a lot of stonemasons to them for tap hole cutting.

The big upside for masons is they can fit a granite/marble top - then core the tap hole in situ as it's not required to be wet cut. Feedback I've got is it take around 45 seconds to core a 35mm hole in absolute black granite which is about as hard as it gets.

We also offer an an M14 to hex converter so the bits can be used in a drill.

same here bri i am going to try ats drills after seeing the feedback from the guys on here just needed something instant today and the rubi grinder bit seems good

they had no feedback as they have only sold 1 so far they said so time will tell it does look sturdy though

As soon as current bits start to die, I will be fading these in. I have 3 angle grinders, need to get one of them doing something!!
