Diamond Core Drill Bit - Ø 52 mm - 450 mm

We drilled 2 solid brick walls 80 cm long dry, using extension and dust extraction adapters. Excellent product.

Great product, works great so far, Drilling into stone.

I am completely satisfied! Great in brick and concrete. Fast shipping. Thanks!

I used it for the first time in brick after a worn out drill and pressed it like the old one. I almost "fell through" the wall. I was surprised how easily and quickly I could work with it. Very good product.

Decisively

An excellent choice in terms of value for money, it drilled the wall nicely. For the time being, I only drilled a brick wall, but he was fine with that.

Excellent value for money. It also carried the panel dry, used more than once.

I drilled with it dry and wet and it fits perfectly. Compared to its price, I think it is excellent.. I see that there is not much difference between the biggest ones..

Fast delivery. I used the crown drill yesterday, great results on a 500 mm long hole. The guide required for this is a self-construction, the core drilling machine is a Holzinger (1 1/4" or 33mm) for a maximum bore of 80mm, purchased from Alpina24 AG in Baar, Switzerland
