Erbauer Diamond Core Drill Bit
This core drill does the job.
i was expecting it to burn out as i had to drill a concrete lintel
no issues at all, even cut through re bar,
good value for money
i would purchase again

Could do better
Overall, this is not a terrible product, especially at the price. However, it would be much more useful if this came as a kit (ie including a long enough masonry bit to provide a pilot hole). The core works OK, although wear was quickly evident, but I spent longer trying to fit the pilot drill bit to my core holder than I did actually drilling.

worst drill bit ever
this bit wore out after cutting 2 inches of concrete. I used this bit AND a larger bit (DIFFERENT BRAND) to cut into the same material using the same drill so i am comparing like for like. My old bit is still good for another five years this one is going back to screwfix.... I am dissapointed because erbauer are usually a reliable brand for blades
