Reseñas de clientes para VEVOR Taladro de Diamante Diámetro de 8-10,2 cm Taladro de Mano para Hormigón Profundidad de 400mm Broca Diamantada 1500W 1100/2400 rpm con Extractor de Núcleos y Nivel Construcción de Hormigón Armado

Matériel qui fait le travail,8 percages de 50mm sur 80cm Carrotages en position horizontale avec quelques retours de courant avec l'eau qui fui du rotor,un peu désagréable. La sécurité 10 mA ne se déclenche pas ?

le seul problème que je voie le connecteur pour fixer a la hause de jardin n'est pas compatible

Bought this to drill 62 mm diameter holes through my foundation. Note I don't have prior experience with such heavy drills, but this one certainly did the job. It's very heavy and strong. Unfortunately I couldn't mount the stand so had to do it freehand, which is quite exhausting and it slapped my wrists a couple of times. Nothing serious though. Only downside is the connection for the cooling water. The hose has some weird slip-on rubber to go over a tap or hose, and a little tap on the drill side. I wish they just substituted the rubber slip-over thing with a gardena connector instead, which the whole world is using anyways. Solving the connections for water on both sides so that you can dose the water more easily would bump this to a 5 star device. For me as an amateur that will use this perhaps 10 times in a lifetime still a very solid device though. Would buy again.

Ca marche bien, mais avec la potence uniquement, en mode manuel c'est presque impossible, du coup beaucoup de manutention quand même.

Fait très bien le travail mais j'ai du modifier l'arrivée d'eau

Ottimo prodotto, di livello professionale.

Machine lourde et puissante. Garre aux poignets lorsque ça bloque. Il n'y a pas de sécurité. Après achat de l'adaptateur, elle va me servir de tarière. Je recommande.

Works good

is een beetje zwaar werk maar doet goed waar hij voor gemaakt is, boort makkelijk door betonnen fundering

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
