Used to cut through 2 brick thick engineering bricks. Once started it continously cut at a good rate with little snag when using a clutched diamond drill. Kept sharp and very little wear on the teeth. For the price you cannot go wrong, was expecting ome tooth damage because of the cost but with the view I only needed to drill one hole considered it a consumable item, however it seems I can put it on shelf and will last a good fair number of holes yet. Far cheaper than toolstation or screwfix and much better quality.

Great core drill bit. Made light work of a cooker hood vent hole. I now have one for sale.

I was involved as a specialist diamond drilling contractor back in the 1970s when diamond core drills cost £100s. This bit is as good if not better than what was available back then. I am impressed.

Great quality and does the job spot on. I needed this to cut a flue for my boiler. I saw there was a lot of different ones out there but for the price, you can’t go wrong.
