I bought this to drill a couple of holes through 8” cured concrete foundation walls. It’s inexpensive compared to pro brand equipment, but seems to be every bit as solid and tight. No wobble, no leaks. After coring two holes, anyway! The drill comes with a valve for shutting off the cooling water. It’s on a very short hose, with a nonstandard quick disconnect. I made up a short adapter that I just clamp on out of a piece of old garden hose - see the pictures. The 4” core bit included is really heavy and solid. I bought a 3” bit, not Vevor-branded, which was made of thinner material, but did the job. Wear your eye protection because it spits and sprays. It’s pretty loud, so I found it less fatiguing to use wearing hearing protectors. To drill, use the higher gear of the two-speed gearbox, if the saw doesn’t bog down, as you’ll cut faster. With larger cores, the motor won’t be able to maintain full RPM in high gear, which is critical for keeping the motor from overheating. The drill does best if you can push the bit into the concrete with a LOT of force. Larger models have drill press like levers that you attach to the concrete, but not the “small” version. I got tired pretty quickly holding it in position and pushing it against the concrete foundation, down in a skinny trench with my arms extended. And then…I hit rebar. It took a long time to grind through, and when I finally did, I could feel the difference. It cuts a lot smoother when in plain concrete. When I finally broke through, the far surface broke through a little before the edge of the bit was all the way to the other side, resulting in an opening that was slightly rough, not crisp. Not bad like an impact core drill would have done. It has a convenient bubble level for drilling vertical cores. I didn’t notice that it also has a horizontal level too, so I didn’t manage to get the hole perpendicular through the foundation wall. It was tilted by 3/8" across the 8” thickness of the wall. I had some trouble brea

Ich habe 1x110 mm & 2x163 mm Löcher in eine Kalksandsteinwand gebohrt. Mit der Maschine ein Kinderspiel. Habe die Löcher "freihändig" gebohrt, da muss man ein bisschen aufpassen, dass beim Blockieren die Maschine nicht der Arm im Weg ist. 😉 Aber die Rutschkupplung greift dann zuverlässig ein.

Todo bien

Je dépose rarement des avis suite à mes achats . Je suis extrêmement satisfait de cette carotteuse . 2 trous effectué dans du béton armé fait très facilement . Juste prévoir pour la fixation en plus Je recommande les yeux fermés

Worked as well as any core drill!

sehr gutes produkt für diesen preis

Very powerful tool, I used it drill a hole on basement concret wall, great tool.

Très bon produit en général, très bonne puissance, fait le travail Il faudrait modifier la colonne pour que l’on puisse la régler sous différents angles

I drilled anchor points for a stair railing and the precision was spot on. Every hole matched my layout marks and the rail seated flush with no rework needed to make things fit.
