We all know the basic rule: If you use a tool rarely, buy a homeworker quality power tool or a cheap one. If you use a tool often, buy a pro or semi-professional power tool.
Allow me to summarize some european brands into four categories:
- Cheap stuff: Lux Tools, Okay Power
- Homeworker Quality: Bosch green, Einhell red
- Semi-pro: Makita, Metabo, Bosch blue (The cheaper ones)
- Pro: Makita, Metabo, Bosch blue, DeWalt, Hilti
Personally I buy drills and stationary tools from the semi-pro category and tools for particular tasks that stay in the shelf most of the time (Belt Sanders, Handplaner, Plunge Router) are of homeworker quality (mostly Einhell). But that is just my personal opinion. I'm looking for numbers.
I've had these never ending discussions with my boss long time ago what would be more beneficial: Buying 10 Einhell red drills or 3 Makita drills for the same price.
Having more drills is great. One breaks? Theres a box over there filled with drills, get a new one. More people join to work? No problem, we have enough drills. The downsides would be more frequent visits to the store to fix or buy new drills and of course transportation and storage of a large number of power tools.
We've had a situation where were we required over a thousand screws for the floor of a terrace and we only had three screw drivers. One guy was drilling the holes, the other two were busy with the screws and the rest were just standing around pretending to be doing something intelligent.
I want to roughly narrow it down to how long each of the categories mentioned above will last. Hours (for any tool), charges (for battery tools), Number of screws (drills)... the variables don't really matter. As the title says I'm looking for a general rule of thumb if possible for all power tools. Also for large stationary tools: If your bandsaw dies and you don't have a big car you've got a problem.
Here is a rule of thumb I got from reading some different articles but I doubt the credibility of these numbers:
- Cheap tools: 5 hours average operation time until failure
- Homeworker tools: 50 hours
- Semi-Pro tools: Somewhere inbetween I guess
- Pro tools: 1000 hours+
