Klantbeoordelingen voor VEVOR diamantkernboor kernboormachine 3000W kernboor 20cm

Seems very heavy duty.. couple slight variations from what is shown in the pic..only came with one set of extra brushes.. and there is a bolt with an anchor that was missing.. but real problem is that the output is very large thread compared to in my pic of a 1.25"" core bit. ahh.. instructions say use adapter.. but there was and is no mention of what this thread is.. (ordered adapter now good to go) and update after using.Other thing I just noticed.. it has Good Qty 120VAC Plug, but it is the 15Amp version, if this device was actually 3800 watts as it is labeled and listed it would blow the regular 15amp breaker very fast.. so far I have only tested no load.Ok we have now done Six 1.25"" Holes and it is working like a champ, we are in an old building and AC outlets are ungrounded, so using a 2-3 plug adapter and so far not one breaker problem, longest penetration was over 12"" solid structural cement, very hard stuff.. and no issues.. 100% satisfaction.. we made a floor mounting system to use on the finished floors rather than bolt down.. I have heard of vacuum systems for same use.. but not having any issues.. just standing on mount to hold in place..

very fast delivery. Excellent product. Drills 25 cm concrete with double iron grid i 7-8 minutes

Very strong core drill. Great for occasional DIY jobs.

You cannot use standard normal DIY core drills without an adapter and they are not easy to find and expensive. Drill has a lot of power and could really do with a clutch mechanism. I just assumed it would have a clutch but this model doesn't.

This is great core drill I use it to core the 8 hole for my kitchen exhaust fan the wall is 12 thick . It is even cut through the metal inside the wall the United rental rent for $280 for the drill and 8 bit , I rather buy this and save for future use since my house is build by concrete slab I highly recommend I am feet happy with this purchase

Love the new core drill
