I look at the boilers at work, and wonder where one would use a tap or die? Calliper yes, although more likely a vernier. We do have taps, and they tend to come as a set of 3, where the ones I got from Lidi only one tap, I have used them to fit grease nipples, but not in the boiler.
Since our boilers are old, most over 100 years old, often imperial sizes are used, and also the pressure of around 150 PSI or more, some do super heat the steam, they are not really items to play with. We have all seen the pictures
these normally kill people, when it happens, so I tend to leave boiler work to those who know what they are doing. I have assisted renewing tubes, but not in charge of the work.
I find in the main I can borrow tools from work, also although against the rules, I have taken tools into work. To borrow something like a drill, the problem is if it gets damaged while I have it.
I can buy a drill from Lidi at say £40 but the one from work likely costs £100 and if it is damaged, down to me to replace it, to borrow a core drill, OK, not much is likely to go wrong, but borrow the SDS drill to drive it, and one is aware it is easy to burn it out.
I have a slide rule, but will normally use a calculator, I have a tree lopping tool, basic a chain saw on a long arm, a proper chain saw would be a lot easier to use, but I can get away with the lopping tool.
I have a tool to crimp pin crimps, but only ever used it once, was there any real point. It looks good,

but when will I use it? Got it to cut brick sets, as yet not cut a single brick. As to my crimp pliers to take 120 mm² crimps, not worked with cable over 25 mm² in years.
And where do you put the tools? Do you really want to store expensive battery drills in the shed? So they are in my bedroom, is that really the place for them?
