Sécurité
2in1 180mm 1pc
Très difficile à tenir et pas d’embrayage. Est dangereuse avec une carotte large et sans pieds. Au dessus de 100mm, je recommande le pieds.

conclusion
j'ai réussit à faire ce que j'avais à faire mais au prix de belles frayeurs à chaque fois que la machine s'est coincée et que je remerciais dieu d'avoir bien fixé le support
Je ne m'en servirait que si je n'ai pas d'autre solution et seulement pour percer au sol et en aucun cas sans le support bien que cette machine puisse être tenue à la main
Pour finir je préciserai que je suis électricien bâtiment depuis 35 ans et que j'ai l'habitude de me servir de différents outils

Hardest 8 inches of my life
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

Bad aftersale service
Hand-held 160mm Machine Only
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.

Unbrauchbar
2in1 180mm 1pc
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

Mr

Très bon rapport qualité prix. Le matériel semble solide et il est puissant en revanche le manque de foret centreur pose vraiment problème, difficile de débuter le carrotage sans abîmer le mur... Dommage !!

Producto peligroso
Hand-held 100mm 1pc
No me ha gustado nada, es muy peligroso de ninguna forma se puede usar sin plataforma y lo venden para usar a mano. No tiene embrague y en mi cas me he lesionado la muñeca. No me parece lógico a estas alturas que se venda un producto así para usar sin plataforma. Lamentable
