Customer Reviews for VEVOR Core Drill Bit, 5.1 cm Wet Diamond Core Drill Bits, 35.6 cm Drilling Depth Concrete Core Drill Bit with Saw Blade, 3.2 cm-7 Inner Thread, Laser Welding, Diamond Wet Coring Bit for Concrete Brick

The SDS plus shaft's threaded insert broke in half, inside the bit, rendering the part unusable after only 4 inches of coring. The entire work day paused.

Don't buy it, I drilled one hole in concrete floor , half the teeth were gone. I drilled the second hole in a concrete block wall, got 1/2 way through all the teeth were gone.

He solicitado la devolucion pero no la han tramitado

I never received the item I bought. They refused to refund my money. RUN!!!!

Je suis très déçu car au déballage, je m'aperçois que le trépan que j'ai acheté en même temps que la carotteuse n'est pas compatible !!!!

It wobbled so bad I could not get it to start cutting the hole. I eventually gave up and drilled around a 41/4 hole with a drill bit and busted it out.

Did not receive

Do not recommend them based of terrible support alone. Its like pulling teeth to get a replacement product when 1 comes damaged.

Can't rate this After 4 weeks the courier (who delivered the core) still can't manage the deliverY of the actual drill WTF

Bought the 2 1/2” core drill bit The pilot bit was not straight. The core bit did not fit the 4” vevor core drill. So I had to use a supplied SDS shank that hold the 2” bit as well as the pilot bit in a hammer drill. First the Allen screw came out which hold the pilot bit. Then the the 2” bit snapped off the SDS shank. Breaking the threads off. Which made the whole set up worthless. The 2” drill is only held on by 3 threads! I was drilling through a non reinforced concrete wall.
