Erbauer Diamond Core Drill Bit 117mm x 150mm
Product arrived promptly. Drilled through a cavity wall with ease. Drill slowly and clear dust regularly. Little sign of wear after several holes. Would recommend this product.

Great core drill.
Needed to drill through a concrete floor, this did the job no problem at all.
Had to drill through about 200mm of concrete (with an extension) and it was a breeze. Just take it slow and steady - it is essential to keep the hole free of dust. Stop regularly and hoover it out.
I still have plenty of life left on the tips, as a DIY'er it will probably last me forever!
You will need a powerful SDS drill to run this bit, ideally a dedicated core drill.

Diamond drill bit
It was a bit more costly than I expected but it did and excellent job so I am pretty satisfied overall.
