I needed to drill 1 4" hole for a dryer vent.. 8 inch of conrete 5 hours latter i finished the hole with a chisel and hammer. the drill is way to fast for a 4" bit.. like double the RPM. a 4inch bit should be run around 600, this drill when i put a rpm meter light on it was spinning at 1200 on its lowest setting. So it just glazes the bit... after having to dress the bit twice I figured out you need to keep feathering the trigger to keep the RPM low. now the drill otherwise did ok. it doesn't like running hot and at it popped a connector inside that i had to take the drill apart to re attach. after securing it properly wit wasn't an issue. it also leaks water around the fitting on the collar while operating, not the end of the world but it does make a mess outside of your hole. The bit is an absolute POS. The "diamond" is a very thin coating that is gone 4 inches in the concrete, so your basically drilling with just steel , pray you don't hit rebar. it also doesn't drill a 4 inch hole it drills a 3.93 hole (100mm) that a NA dryer vent doesn't fit into without modifing it. which is the true feeling of utter defeat after spending that much time slogging it out behind the handles of the drill So if you are doing 2-3 inch holes.. buy this drill, without the cheap vevor bit. then buy a decent bit that has a NA brand name on it, you should be fine

Ganz furchtbares Gerät. Wie zum Teufel soll man die denn an der Wand fixieren. Extra kernbohrgerät Beton Dübel mit Innengewinde gekauft. Es ist praktisch kaum möglich, so exakt zu bohren, das die Schrauben vom Fuss exakt passen. Diese haben ebenfalls ein Gewinde. Das ist doch totaler Müll. Würde gern Minussterne vergeben

Je deconseil fortement, il es indiquer maximun 200mm et percage seche. J ai fait 1 trou en 200mm dans de l aglo, au deuxieme trou la machine etait bouillante, des etincelle sorter de la machine et elle c est mise a fumer. J ai utiliset un perfo a 100e de chez brico depot avec racord sds j ai fait les 3 trou qui me manquer.

Utiliser 6 fois est deja en panne

I never was able to use it you will biy this thing and go to waste is not possible to use it even with 2 man you need an stabilizer skeleton or something serious

Não comprem não serve para nada...

machine dangereuse

Unfortunately, I ordered the machine without a drill stand. Therefore I wanted to buy the drill stand separately. When I contacted Vevor, they recommended to buy the drill stand from another supplier, because they don't sell the drill stand for the machine separately. That's the joke of the day. They're selling products on a "take it or leave it" basis.

Maschine ausschließlich im Bohrständer zu verwenden! Keine Rutschkupplung was bei Bohrkronen gefährlich ist, sehr hohes Verletzungsrisiko. Die Maschine zieht durch bis sie durchbrennt Mit 80mm Bohrkrone ist der Ständer einigermaßen nutzbar, wenn sich eine Größer Bohrkrone verkeilt wird einem Der Ständer um die Ohren fliegen. Wer nur wenige kleine Löcher Bohren muss und sich dafür Zeiiiiit lassen kann ist die Maschine i.O.
