Good quality and great value

Good for the money

I will not be returning this product it was the package with rawplugs in

Just the job. Nice set, should last a while.

not fully tested yet,

If your like me, you pop in the drill bit and give it a quick spin. It lets you know its spinning the right way, and is true, meaning you can't see it moving about, spinning just right.Sadly the second time i went to use it, i did the same test as i always do, but i was shocked to see the drill bit moving a large amout, meaning no longer straight.If i drilled a 8mm hole, it would be more like 10mm, tgats how far out it was, the shaft is not hardened, so soft it easly bends.Theres 4 in a pack, watch this space to see if the second one does tge same.Using a Makita hamner SDS cordless drill, i have another SDS drill bit, must be 4 years old, still straght, after all the work that done.If the next one goes bent, ill be callling Amazon for a return.I also bought the 10M and 6M not tested them yet.

the larger drill bits OK the two smaller bits not very good , overall that is what to expect with the price,get what you pay for

Really good

Sehr gute Beton Bohrer zu einem fairen Preis. Sehr zu empfehlen.

OTTIME, MATERIALE BUONO, LE CONSIGLIO.

Bereits mehrfach verwendet - arbeiten sehr gut und schnell.

Prodotto buono ma con qualche piccolo problema nel montaggio sul trapano!L'unico motivo per cui non do 5 stelle è che hanno la base con degli intagli laterali e quando si deve serrare la punta nel mandrino del trapano se non si fa attenzione la punta rischi di montarsi storta
