No adaptor for anything else included. My mistake. Good luck getting a hold of customer service, and if you do find someone is useless; this is a bad place to buy. I need to return it as this is no good to me, but the customer service or contact system here is ridiculous to talk to anyone; I will contact my credit card.

Hi. The cutter is good, but the center drill is short. It's unclear what it's for if it doesn't perform its function.

bonjour je souhaiterai une facture pour l'achat foret diamant carotteuse

Een serieus oordeel over de kwaliteit kan ik helaas niet hebben omdat ik maar 1 gat hoefde te boren en dat ging goed. De meegeleverde centerboor is niet lang genoeg en steekt er dus niet uit om als centerboor te gebruiken. Hierdoor een andere centerboor erbij moeten kopen die wel uitsteekt om de klus af te maken. Verder raad ik ieder aan om wel met water te koelen. Bijvoorbeeld met een plantenspuit of iets dergelijks.

Bought the core drill to make 2 holes for a pool stair ladder into concrete. The 9 1/2 core drill worked well cutting through the concrete while applying a steady stream of water. My problem with the product is that the pilot bit that centers the core bit is only 9 inches long, the drill bit is useless to keep the core drill centered when trying to establish the hole where you need it. I had to cut a 3 inch hole into a piece of plywood and use that template as a guide so the core drill drilled the hole where I needed it.

Did pay attention i guess during purchase as i don't need dry drill bit. I guess they'll just sit in the box, to much pain in the ass to return. Im sure it a good bit thou.

Zentrierbohrer zu kurz, daher sinnfrei. Mußte einen anderen Bohrer benutzen. Lieferungzeit zu lange, Verpackung mangelhaft, Tracking undurchsichtig Die Serviceabteilung gibt vorgefertigte Standard Antworten, nutzlos. Die Bohrleistung ist gut

The center pilot bit is too short and does not protrude out the end of the hole saw. I did try and pre-drill the pilot hole without the hole saw and found the hex screw would not stay tight in the arbor, so the pilot bit is basically useless. While the kit comes with 3 adapters, the threads are very loose fitting and the SDS Plus in particular only had a small portion of the threads engage inside the hole saw. I'm surprised it didn't strip out. It seems like this "KIT" is really just a bunch of random pieces they threw together and are not specifically made to fit together. While the hole saw did seem to cut through the masonry block fairly well at first it became less effective near the end of the 8" deep hole. If you only need this item one time, don't need the pilot drill and are sure there is no rebar then the price is good for a DIY'er. Just don't expect to put this tool in your kit and use it reliably in the future.

Attrezzo di pessima qualità usata per 3 fori in un muro non di cemento armato, la carotatrice si e rotta.

La punta si è disintegrata a metà durante la foratura di un condotto in cemento. Anche se si presentava bene e con tutti i suoi accessori Il costo basso mi aveva comunque già allertato. Ideale solo per forare al massimo dei mattoni con un po' di cemento
