Recensioni dei clienti per VEVOR Trapano a Colonna Elettrico Perforazione del Calcestruzzo Potenza Nominale 3200W Diametro Max. 20cm, Macchina Carotatrice Elettrica 750 giri/min Umido & Secco, Trapano per Carotaggio Diamantato

Super carotteuse j'ai percé 2trous de 18cm de diamètre dans mur en pierre de 50 cm de profondeur sans forcer environ 2 mn par trou. Par contre la mise en place à été très compliqué la machine est très lourde et grand porte à faux. J'ai pris le modèle plus gros car il y avait rupture de stock sur la petite.

This thing blew my mind for the price, I charged a customer $600 per hole to core and with the money we made in one night we could outfit a whole crew with each a paid off machine

I was skeptical based on price, but I was suprosed by the strength of the machine. I use (4) 3/8 x 3" simpson titan HD to mount it to the wall. Couldn't figure out the water adapter that came with it, so expect to need a hose to keep it cool. Hit a piece of 5/16" steel with the core bit and it slowly ate through it, very surprised. Looking forward to using it for whatever core I need to cut out next

Worked flawlessly was better quality then expected for the price .drill preformed as well as 2000 dollar drill with no issue at all while drilling a 5 in hole

Did a great job on the job for me. Price was right and quality was surprisingly good at that cost point.

Great little machine has plenty of power. I may install some sort of rod or something for cable management, you actively need to manage the water and power cable because they want to rub against the core bit while the tool is in use because of where they feed into the machine. Also the base really doesn't need female threaded holes for the included bolts. It would be nice if the bolts just slid right through instead of having to unscrew them after each hole you drill. Not really complaints, just suggestions for future improvements. For the price this thing is definitely worth it and I would strongly recommend it if your on a budget.

Drilled 10 4.25" diameter holes in my retaining wall at depth of 9" each. There were not many instructions to put it together, fortunately, it didn't really need it. They ship it a certain way, you have to take it slightly apart and put it back together the right way. The feet go on the "front" of the pedestal. The feet were essentially useless for me (though they would be great in most other scenarios). It would have been a great little addition if they had included the $4.00 garden hose adapter you need for the water. Additionally, a 1 1/4 to 5/8 attachment would have been great. I also wasn't sure what two of the pieces were for (they looked sort of like fuses, but I have no idea what they are). Aside from all of that, it was GREAT! I have NEVER drilled a core out in my life and I got 10 with this one core bit and core drill and they were exceptional. I DID predrill, though. I used a concrete bit in my hammer drill where I wanted the hole and a "throw away" 4.25" hole saw to score the blocks where I wanted the holes. It helped me line things up perfectly. Go SLOW at first. The big will catch on the ground if you go too quickly. So just take your time. Once you get a bit deeper into the core, you can push it a bit faster because the bit has the support from the walls. But until you get down a bit, it'll catch and (if you're not standing on the drill plate on the back) throw you around. Make sure to TURN OFF the machine before pushing the reset button. Always restart from scratch. Turn everything off, reset position, buttons, etc. Then start. 5 Stars because it did exactly what I needed it to do without any additional needs, saved thousands of dollars, and looks like it'd be able to do it for a lot longer.

High quality and great price. Fast shipping. Excellent customer service. This unit is strong and it comes with everything you need to start core drilling.

Cette carotteuse fonctionne parfaitement et offre un excellent rapport qualité-prix. J’ai déjà réalisé deux carottages dans un mur en pierre granit de 500 mm. Il est un peu lourd et difficile à utiliser seul, mais je le recommande vivement.

Vaya por delante que aún no he usado la máquina por lo que en cuanto a funcionamiento todavía no puedo hablar. En cuanto a la atención y servicio, de 10, pedí la máquina un domingo y el martes ya la tenía en la oficina, pedí la factura y me la enviaron al instante. En cuanto al aspecto de la máquina bastante bien (lógicamente no es una HILTI) pero el soporte es de un aluminio bastante resistente, el motor combina aluminio con plástico bastante aceptable. La máquina te la entregan con una corona de diámetro de diámetro 100 mm. Los segmentos de corte a simple vista no tienen mucho diamante pero ES GRATIS, cuando pruebe la corona volveré a comentar. También te entregan dos (2) escobillas (o carbones) y una llave fija 36 para el desmontaje de la corona, todo esto de cortesía. La máquina también viene con el tornillo de fijación o anclaje de la máquina, es un tornillo métrica 16, que en mi opinión es demasiado grande, requiere tacos de fijación M-16 para lo cual se precisa un taladro diam. 20, que yo creo que es excesivo. Seguiré empleando la fijación de mi antigua máquina que era M-12 y con la cual nunca he tenido ningún problema. En cuanto a peso es aceptable, por poner una pega diré que el mando eléctrico que va en el cable tiene una carcasa de plástico con aspecto muy frágil o de fácil rotura (le he puesto una protección exterior con otro plástico para evitar que al soltar el cable el mando pegue en el suelo y se rompa. El resumen final es que por el precio que tiene la máquina está muy, muy bien, hago esta afirmación a falta de probar en obra la máquina. Cuando haya realizado varios taladros volveré a escribir el comentario final.
