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

Na občasné vrtanie stačí.

Elle a déjà bien morflée depuis sa réception. idéale pour les passages de canalisations en 100 mm ou de fils électriques avec une fraise de 60 mm avec une profondeur de 400 mm.

Matériel lourd faire très attention lors de l'utilisation de ne pas forcer il faut laisser la foreuse travailler car si elle se bloque vous prenez un retour dans les bras

Je suis très content de mon achat j'appréhendais au vu des prix pratiqué pour le même produit mais il n en est rien le produit est fiable et de qualité je recommande

El gatillo es bastante progresivo, lo que te permite empezar el agujero despacio para que la corona no baile en la superficie lisa. Una vez que entra, puedes darle a tope y hace el trabajo en un santiamén. Muy recomendable.
