@Max... "it's not that I don't use the tools, but when I do so I'm in my garage, so power isn;t a problem."
As soon as you need to make a hole more than about 5 feet away from a power point you either have to find an extension lead or use a cordless tool. I have a drill and charger hanging on my garage wall, so it's usually the latter, unless it's for a hole in bricks, which my cheap small cordless can't do.
At work I have to work on vehicles and radio huts and the like, so I have a range of cordless tools including an angle grinder, I would not be without them.
It's very much horses for courses, though,
And I'm pleased to see there is someone else who hits the ; instead of the ' and types things like "isn;t". My dad once said he had five thumbs on each hand. I'm even better - I'm ambidextrous - no damn use with either hand :-)
Also very neat. I don't think you could use either of the above for anything harder than wood. I have a set of spade drill bit which are similar but not adjustable, I was just using them the other day to sink bolt heads into a plank of wood I was mounting on a wall to hold TV screen mounts.
Another example of a tool which you wouldn't use very often, but when you need it, very little else will do and it makes the job SO much easier. The guy who invented that must have fitted a fair few new door locks in his time.....
@max...well my Tuff Sucker has not broken, so I guess it is tuff...but it certainly does not suck like an Electrolux. Once it gets the smallest amount of dust in it, it does not suck very well at all (in fact its sucking sucks, if you see what I mean.... :-) You then have to take the filter out and wash it. But in the main the Ryobi One+ tools are great.
I don't like to make chips when I make holes, so whenever I can I use either a number 5 jr hand punch (depending on punch and die installed, it makes a hole up to 1/32 over 1/4 inch) or a model XX (up to 1/32 over 1/2 inch hold, again depending on punch and die set installed). Harbor Freight has made cheap copies of both but they are sporadically available, the punch and die sets are not interchangable for the XX copy. Thr original models are currently made by Roper-Whitney, the best current maker of Sheet Metal tools including cutters that cut a 90 degree notch (and other angles) with one squeeze. All these tools are meant for sheet metal, usually flat. The XX is my favorite, mostly because I have the punch/die for D-shaped 3/8 hole needed for BNC jacks. Ebay has the basic punch and bsic set with 7 punch and dies, but it is a little tricky getting other than standard fractional round hole-maker punch and die sets. Quote last year for a replacement D-shaped 3/8 set was $90.
@TonyTib: Since I don't tend to use power tools a lot, I've been mostly buying corded tools: they give lots of power without having to worry about charging the battery or paying for Lithium batteries.
I'm 100% with you on this -- I don't think I have a single battery-operated tool -- it's not that I don't use the tools, but when I do so I'm in my garage, so power isn;t a problem. I guess that if I was on a building site doing thsi every day, I'd be more tempted to use battery-powered versions.
Last time I used a nibbling tool it had a squeeze handle. Powered now - cool!
There was a time when very small "hole saws", with 2 teeth, were used to manually cut about 1/8 inch diameter islands in copperclad pcb material for breadboarding. Don't know if they are still available.
