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

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.

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 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.

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.

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

Super

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

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
