Goede kwaliteit

Looks good and will be ready for the next round of doing some holes. Fast shipping

Absolutely fantastic core drill. At least as good as my other core bits, at a fraction of the price. Have cored 6 holes at least 6” thick, and one 14” deep that I modified how it mounted to go that deep, through rebar and 50 year-old hardened concrete There’s still a solid diamond abrasion edge. Truly blown-away at the value.

Great price product and delivery , will do biz again

Prima diamantkernboor voor sporadisch gebruik

Trépan utilisé pour un mur de briques en épaisseur 33cm. Pas de soucis, c'est passé vite et bien. RAS.

Qualité incroyable pour le prix aucun cie peut avoir ca pour ce pri ( dommage qu'il n'ont pas beaucoup de grandeur ? )

Quick shipping of a quality bit that worked perfectly.

We needed to drill a couple of holes through two layers of very old and brittle concrete block wall. It was important that we not 'blow out' the outer wall. Although we drilled a pilot hole to locate the outside hole which had to be slightly lower than the inside to allow for heat pump condensate to drain, and then finish the hole by drilling in from the outside, it proved unnecessary as by carefully slowing the drill as it approached the measured depth to the outside wall, we were able to stop the drill and simply push in the very thin remaining layer leaving a perfect round hole with no damage on the surrounding concrete. We drilled two holes in all and the bit seems untouched. Very good value.

I used the core bits with out water on a 100 year old brick. It worked great! It didn't wear at all really. I would highly recommend this tool
