Broca de coroa diamantada, 102 mm, 356 mm de profundidade

Take it slow and let the tools do the work

Worked well on drilling 8" reinforced concrete. No blow out on the other side of hole

Bonne couronne

Bonne couronne pour des travaux occasionnels

Keine ganze Bohrung gehalten

Ich habe bisher nur die 102er Bohrkrone verwendet, diese hat leider nicht eine ganze Bohrung gehalten und fängt vorher schon an zu glühen. Die anderen Größen konnte ich noch nicht ausprobieren.

Not bad. Not expensive.

Great price, you won't feel bad about leaning into these bits to get outta there early on a Friday afternoon. Can buy 2 kits and still spend less than one bit at the big brand stores. That's 2 early Fridays for more beer time my bros

Befestigung Leitbohrer

Bohrsystem entspricht nicht ganz den Erwartungen. Beim Arbeiten mit Schlagbohrmaschinen löst sich ständig die Befestigungsschraube des mittleren Leitbohrers und fällt heraus. Bohren wird dadurch uneffektif weil die Befestigungsschraube immer neu gesucht, neu eingeschraubt und der Leitbohrer wieder neu befestigt werden muß. Die Lösung mit Madenschrauben scheint suboptimal weil über den Sechskantschlüssel nicht genug Klemmkraft aufgebracht wird.

Core Drill

Incredibly well put together—I am very surprised.

Epic Fail!

Not useable, the pilot bit is to short and wiggly, causing major sway in the start up of creating the hole, had a friend go home and get his hole saw, going to be returning this, sorry the brand, still a customer though, bought a 30"+ pole saw, worked and did the job, but this was an epic fail!

Goede kwaliteit.

Nu een maand in gebruik en doet zijn werk naar behoren.

Tolle Teile

Sehr schnelle Lieferung, alles in Ordnung

Good quality. Did exactly what I needed.

Good quality. Did exactly what I needed.

Ça fait le taff!

A travers le parpaing de 20cm pas de problème! Impeccable.

Nass gut, trocken gar nicht

Nass bohren funktioniert, trocken nur leider gar nicht, da er zu schnell erhitzt. Doch um den Preis, zum nass bohren, zu empfehlen.

Bohrkrone

Sehrgut tolle Lieferung und sehr gute Qualität

Great Core Bit

Drilled 6 holes through about 5” of concrete. Performed as well as any bit I’ve ever used Will definitely purchase more of these. Can beat the price and delivery was faster than expected.

GUUUTTT

Beton mit Stahl hat das super durchgeschnitten, GUT

Very nice product

Did a few hole in concrete house basement and it went well

Helaas, had zo mooi kunnen zijn

1 gat van ongeveer 5 cm geboord in beton en toen brak een van diamantelementen af. Helaas boor vast in het gat, met het eruit wrikken, scheurde nummer 2. De 5 cm ging ook niet heel soepel (gewapend beton). Dus toen maar een iets duurdere besteld., dag later in huis. Die doet het als een mes door de boter (Distar DDS). Maarja op dat moment kan je dus niet verder. Zitten wel een hoop adapters bij deze boor, dus je bent wel gelijk klaar. Misschien had ik een maandagmorgen model, anders was het wel waar voor je geld. Nu niet, dus helaas maar 1 ster. Geld wel snel terug gekregen na de reclamatie, daar geen klachten over.

Helt enligt beskrivningen

Funkade hur bra som helst till de jag skulle ha de

Thread size - off standard

It looks to be a good quality product with sharp cutting teeth. Unable to locate an SDS attachment to suit locally as the thread is an off size. Will have to return

Heavy duty easy borin in brick great product

I bought this while boring a hole in a brick wall for a mini Split it done a great job i would recommend

Super le top

Le top du top . J’ai réussi à percer un mur de 40 cm en diamètre 5 cm. Rien qu’avec une visseuse à percussion à batterie de chez Lidl. Incroyable ce trépan. Très solide, on peut même le brancher sur une perceuse SDS plus et SDS Max. J’ai impression que c’est encore plus solide, que ma bosch qui me coûte cinq fois plus cher.

Excellent drills

These drills are excellent for the price. Used in many works and all is fine.

SDS aufsatzt

SDS anschluß, geht gut durch Porenbeton und Poroton

Slechte bezorging en onvolledige site

Veel te laat bezorgd, niet conform hún toezeggingen en jee zit niet standaard een adapter bij dan wel duidelijk aangegeven dat je deze nodig hebt. Nog niet mee geboord.

It works!

Drilled a hole through my wall without a struggle. The only thing I would change is the pilot bit. I wish it was an inch longer than it is. Other than that, great bit at an affordable price. Definitely excceded my expectations.

très bon produit

arrivé dans les temps prévu, carottage effectué d'une dalle béton de 15cm d'épaisseur facilement avec une grosse perceuse sans la percussion

Handyman

I bought 5 inch, but the actual diameter was 4.5. I don't know why. I drilled 2 holes in foundation strip with deep 22 inches.

Solid tool with potential improvements

I’ve purchased this tool to install a mini split AC system in my garage through a block and concrete wall, although the work was done, I ran into some difficulties with the pilot bit, the adapter I used was the SDS-plus and the pilot drill bit to do a pilot hole through the wall, the bit is attached to the adapter with a side screw that lands on a flat side of the bit, the problem was that with the vibration the securing fastener always came loose no mater how tight I tried to secure it, I ended up using a different drill to make the pilot hole and once assembled together with the barrel was a little better but still managed to get loose several times, if the drill bit came with a notch for the securing fastener to land instead of a flat surface probably there is a better chance of keeping in together. Overall, got the job done with some hiccups

That the center drill is too short

Bought this item in July and when it came time to used it I discovered that the center drill was too short to to drill a starting hole. Other than that, it performed exactly as was indicated and I would recommend to others.

Può andare

Valutazione ottima ma non eccellente. Da migliorare la punta di centraggio che dovrebbe essere più rigida per iniziare il foro con più precisione, perché a causa della rotazione tende a ruotare più ampiamente rispetto al fulcro. La qualità della tazza è buona. Provato sui forati.

Souveränes Produkt !

Schnelle Lieferung! Super Produkt. Gute Verarbeitung und hält was es verspricht in der Beschreibung!

Owner

Purchased this set 25mm to 152mm hole saws. It did not include the adaptor. I do not see it .on your website. Can you help me with this.i can’t use them without it

Does the job BUT

It does the job. I drilled a clean hole through 2-3 inches of brick to feed my hose through the wall. Maybe it was user error, but with the guiding pilot bit in, the main core just wobbled around way too much to bite into the brick. So what I did was cut out a small hole in a piece of plywood, then anchored that into place and used it as a guide. No issues after that, it just took a while. The hole was very clean. I then threw a pipe and 3D printed an escutcheon.

Résultat perçage

Impeccable. Trou propre et facile. J'ai pu glisser un morceau de tuyau de 100 à l'intérieur ce qui fait un trou nickel. Je recommande. Attention toutefois, lors d'un premier forage ce n'est pas si facile surtout lorsque l'on travaille sur un crépis fini. Il faut bien tenir l'appareil, l'appuyer fortement et l'incliner légèrement. Ensuite, dès que l'accroche commence, il faut appuyer tranquillement et tout se passe bien.

Bohrkrone

Gute Verarbeitung ist leider nur mit geringer Geschwindigkeit zu verwenden da Sie stark Vibriert

Purchaser

I thought the bits were going to be garbage because of the price, so much so that I purchased 2 bits. Boy was I wrong. Drilled 6 - 3" holes in two days. The bit was slow on the second hole, I thought it was the bit dulling out but it was lack of water. Turned the water up and it was like a hot k ice through butter. 8 minutes to drill through 4" of fired brick. Awesome drill bits.

Worked for me

Good value for the price. I only used it twice to make holes for radon gas pipe. Perfect fit for a coupling fitting of radonx 4 inch pipe. One hole in the basement floor of just under 4 inches thick. One hole in a concrete block wall 10 inches thick.

Mr.

Super Preis Leistung. Günstiger als jede Anmieteung im Baumarkt.

Fait le travail

Acheter pour percer un bloc béton 14cm avec placo de 12,5 pour une évacuation sanitaire de 50mm. Facile a utiliser a sec, ne pas forcer trop fort, avancement lent mais l acoupe est assez nette et au final, le trou est légèrement plus gros que 50mm ce qui laisse un petit jeu pour passer le tuyau. Effectué un pré perçage avant depuus le sens de sortie pour guider la carotte avec précision dans le sens de coupe

Punta a tazza per carotare

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

Property manager

Tool works well, cut 4 holes in 4” concrete quick. Center drill bit does wobble a bit. You can drill your size hole in plywood or oversized 2X material and use that as a guide. Solves wobble problem until you reach 1” depth. Great bit. Keep tool and drill as straight as you can and it does the work.

commande carotte

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

Attenti nell'abbinare la punta delle dimensione esatte.

Purtroppo il prodotto non era descritto. Per cui ho fatto degli errori nell'acquisto della punta diamantata che per le dimensioni non corrispondenti non si avvitava. Ho dovuto acquistare un adattatore e fare alcune modifiche. Non sono soddisfatta. Questo genere di prodotti, specie se provenienti da paesi esteri, dovrebbero essere corredati almeno di una descrizione (anche in inglese), infatti si può incorrere in errori specie se di vogliono abbinare degli accessori.

Mr

Ok, só depois de trabalhar uma vez é que poderei dizer algo acerca do aço e do diamante

Ça rentre tout seul

Version avec découpe sous eau, cela rentre sans forcer dans mon lit en pierre.

Bit is a light weight heavy duty enough for cutting. Threads match the hand held drill great.

Core drill bit

It works great drilled in some posts holes into bedrock. Can put it in your normal drill, I use that hammer drill which is not recommended for coring holes.

Great drill!

I needed to cut two holes in the concrete floor for a toilet and shower drain. Floor thickness about 4 inches, and super solid, 75 year old concrete. This drill did the trick. My only precaution is that once the main circular bit starts getting a bite on the concrete, REMOVE THE PILOT DRILL!! It's pretty tiny and deflects easily, so it will follow a different path than the core drill, and will likely break. Also had to take a break about every inch or so and chisel out the core.

Fast shipping

Item are very good and really good quality but it doesn't come with an extender for it or a bit. Now I have to go look for one

Top boor

Aangeschaft om gaten voor spots te boren in mijn oprit tegels. Is goed gegaan. Mooi dat er drie aansluitingen bij zitten

Onbruikbaar zoals het geleverd wordt.

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.

Bit worked very well with Bosch hammer drill!
