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

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.

I've ordered this bit twice now. One was supposed to come via post office, the other Fed Ex. Both shipments made it part way and then sat there for 3-4 weeks without moving. Kinda hard to believe 2 delivery services can't get the product delivered. I never received either order but did get refunds on both orders.

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.

Acheté avec une carotteuse, mais Ne se monte pas dessus, donc inutile.

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

No help at all.
