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

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.

The pilot bit is too short to fit through the end of the core drill. It's very hard to get started without "wondering". The pilot bit is also of very poor quality.

habe das Teil noch nicht weiter getestet, vom rein äußeren Erscheinungsbild macht es einen guten Eindruck

Outil bien pour la brique pas très performant pour le béton

The bit works better than expected but not perfect. I drilled though 2 - 8" thick 40 year old concrete walls. The bit still has life in it. Be aware that cordless hammer drills will work with this, but they will struggle and it will be slower. When I switched over to a corded electric hammer drill, it worked much better. Now the not so good part. The pilot bit is not long enough to be a pilot bit. I used a small concrete bit and drilled holes around the parameter with that to give me a deep enough groove to get started. Once I had a groove it was easy to continue. Every inch or so I stopped, let everything cool and chiseled the center out of the hole to prevent unneeded friction. I good pair of leather gloves are a must. It is long enough where I found I needed to loosely hold the bit while starting out.
