"Never used the Erbaur range before, but it all went smoothly, although it is important to follow the manufacturers guidelines re drill speed and patience! Easy to assemble with the Hex arbor and the guide drill. Drilled thru a 20 x 10 x 5cm block paving brick and it was a neat, right size drill hole. Special thanks to the staff at the local Screwfix store who sorted everything I wanted in about 10 minutes flat! Great service! No hesitation in recommending this brand / product"

Review 4 for Erbauer Diamond Core Drill Bit 38mm x 150mm
"Used this to slowly bore through a 10" solid brick wall, it was a case of being patient and letting the cutter do its stuff. The secret too success is to run the drill on a slow speed and keep on cleaning the hole out. As for reliability, I can't really judge after just one hole, but it was working as good at the end as when I started."
