110mm Diameter Sds + Tungsten Carbide Tipped (Tct) Core Drill

I bought this to core drill bit to cut drainage holes through a 100mm concrete block wall. I couldn't find out anywhere what depth of hole it would cut but I took a chance anyway at this price. As it happened it would cut successfully to a depth of 50mm to 75mm (the bit is probably about 80mm depth). By cutting, then using an SDS point chisel to clear the hole, and cut and chisel again I successfully cut 6 holes through the wall in probably just over an hour. The bit was cutting as well on the 6th hole as it was on the first and still has plenty of life left in it. I honestly thought that at this price it would maybe cut one or two holes before getting blunt but I was delighted with it's performance and certainly it's price.

Bought this after buying a full Diamond core bit kit that didn’t quite do the job

Maybe not the best quality, but did the job well enough through a concrete block wall. Cheaper than hiring the core drill, but needs a fairly powerful SDS+ tool to drive it. (Make sure the bolt holding the centre drill bit is tight!)

I had to make a whole for my kitchen hood exhaust. I looked for a lot of options and nothing was on my budget. Also didn't want to buy some expensive bit just to be used once. I found this one and thought to give it a try. I am quite good at DIY so I managed to get the exhaust hole through my double brick wall. It's not quiet and makes a lot of dust and a lot of mess and took ages to get through the wall but it did the job along with my SDS drill. It survived and it can probably do some more holes in the future. I for one give this small gem a 5 star value for money. It will do the job if you know what you are doing and don't mind the mess or the time it takes to finish.

This core drill bit works well, but it's a bit noisy. Ear protection is a must.

Excellent, prompt delivery

I got some problems with my core bit but saller is resolved my problem and sand me new corebit it works fine for one or two jobs but what you pay what you got i save good money for my self I recommend you

Only 50mm deep so does not cut through a standard brick.

ein Loch bohren hat wunderbar funktioniert, ein Stern Abzug, da der Hinterteil (Stellschraube) eher aus weichem Material besteht. nicht zu fest anziehen.

Prodotto arrivato in tempo, si presenta bene, ma è presto per dare un parere.

Lo compré para hacer dos agujeros de salida de humos, se portó como una campeona de precios mayores. Cabe decir que no tuvo que atravesar hormigón. Quedó como si no hubiese trabajado. Buen peso y a un precio, en comparación, irrisorio.

Ai dû « marquer » le cercle avec la cloche. Ensuite forer avec mèche de 6 puis de 8 dans le cercle. Employer burin sur marteau perforateur pour enlever la brique dans le cercle. Enfin, « égaliser » l'orifice avec la cloche pour un beau résultat. Ne pas essayer avec la cloche seule. Ça n’avance pas.
