I never rent stuff, I either buy new or used.
This is true for stuff that is in the few thousands range, obviously if I need a tractor, things are different.
Anyhow.
I am installing a new ventilation system in my house to put it up to code.
This a Continental Euro house, so everything is a mix of concrete, ciment and brick.
The holes in the ceiling fron the attic to the 1st floor are 180mm wide.
I normally do these with a heavy percussion drill and a percussion hammer.
Getting through the 30cm takes less than a hour per hole.
However, everybody was insisting I rent a diamond boring drill...
Everybody as in the ventilation supplier, the architect, the contractor etc.
I finally give in and on their recommendation go to Huurland.
The price on the web page was 79€ per day + wear on the diamond bit.
A guesstimate from their info put it a 100 to 125 for the day...
Ohh, how wrong I was...
Setup was a chore as this model needed 4 anchors.
The machine was incapable of completing a single bore, probably because the concrete is heavy on quartz/hard stuff. The thing would torque lock at the slightest pressure. Carbide has no problem as the hardness makes it brittle under impact.
Used more than 100L or water for the effort. Did a giant mess.
So I went back to the store after two hours.
They made me pay the full price on EVERYTHING, totalling 211€ for NOTHING.
Tried to tell them about the 79€ price on the website, but having my deposit, they had me by the proverbials.
What a ripoff!
A good second hand machine is worth about 900€ and can be sold on after a week for 900€ minus postage. A drill bit fit for the purpose for about 80€...
Or 35 € for a premium bit for my drill that could probably last for twenty of these holes...
So yeah, I feel stupid right now.
