"the only cordless tool that is not worthless is a drill."
That's a load of crap. Use good tools.
My cordless Makita circular saw will cut probably 30-45 linear feet of 3/4 plywood or maybe 40 2x4 cross cuts on a battery charge.
Yea - I wouldn't use it for framing a roof deck, but to say it's useless is bullpucky.
The cordless planer will scribe all the counter backsplash and filler strips you'd need in a kitchen on a full charge.
The cordless miter saw (full 10" with full kerf blade) will cut all the base moulding and case molding for 4-5 rooms on a charge
The cordless Jigsaw just about makes your corded model obsolete except for the better guides on corded models.
The cordless vacs rock for basic cleanup for quick little jobs or even a quick hookup for the Domino or belt sander o pocket hole jig.
The cordless metal cutting saw will rip 1/8" aluminum sheet or even make multiple cuts on full thickness 1/4" 2x3" steel angle. It'd cut countless amounts of steel conduit or other lightweight construction steel supplies.
The cordless grinder is not for refinishing a car frame but excels for quick cut-up tasks with a 1/16" cutting wheel or will cope trim with sanding discs without the hassle of a cord.
The cordless recip saw will do a small room's worth of demo cuts if needed.
I've evened used my cordless hammer drill to do a series of holes for a 8" diameter hole for an exhaust fan in exterior brick. (I do have a corded rotary hammer..)
To say they replace corded models would be ridiculous, but to say they're useless is stupid. Used within their inherent limits, they earn their keep every single time you use them.
Yea, I wouldn't build a deck with a cordless circular saw, but you could certainly run all the decking with a cordless impact gun and run all the lags with a cordless impact wrench.
Most folks who complain about cordless tools:
- old farts
- using cheap tools
- don't treat their batteries good (exp: charge when hot, leave on charger, drain batts fully...)
- try to use them outside their limits
I can go to a job to install a new entry door and sidelights and do the entire job with cordless with just a few batteries. This includes some basic demo, modifying etc.
I'm not too invested with cordless nailers, as I like the variety of having a few different guns around, though I have a paslode 16ga gun.
I wouldn't be without my 15amp 7 1/4" circ saw, 10amp sawzall, or 12" miter saw, but I use those tools less then I would otherwise on some jobs because of the cordless options.
