So I feel I’ve outgrown my $15 Aldi calipers. Actually, they’re junk: use more than a battery per year since they never truly turn off, but above all, depending on how you hold it, they often skip, so returning to zero suddenly the number has gone up in 2.54mm/0.1” steps, usually 5.08mm. I’ve fucked up countless measurements because of this. It’s easy to notice an added 5mm when measuring something that’s just 3mm, but on a 50mm object it’s not obvious. As the battery drains, it gets more and more sensitive to spurious jumps.
So it’s time for something proper. The local tool distributors carry a number of brands, and the ones I’ve been looking at are Mitutoyo (duh), Sylvac (Swiss) And Mahr (German). In fact one distributor has a sale right now covering a few models from each. (US brands are less likely to be available here.)
So what do I need to look for? I know I want the thumbwheel (any reason why I wouldn’t want it?), and ideally bigger digits. I also know the standard 6”/150mm is more than enough for me at the moment. I also don’t see any need for a data link. But what else should I look for? I assume IP67 rating keeps dust out and theoretically improves longevity, right? What about jaw shape? Micrometer resolution? Square vs round depth gauge? Carbide jaws? (Expensive!)
[Edit: since it doesn’t seem to be clear, I’m expressly asking for help evaluating which of those features make sense, because the range of models is overwhelming.]
Some models list “inductive” sensing. Others “absolute positioning”. What should I look for?
For what it’s worth, I was using a mitutoyo recently and, just like the instructor warned me, it was hella easy to accidentally hit the hold button and thus inadvertently not take a new reading at all. Didn’t like that button layout.
They’ve also got some sets on sale, with a caliper, micrometer, and various metalworking tools. I don’t think I need a micrometer, but is it worth having?
My actual needs are modest. I’m measuring mostly things like screws, components, cutouts, etc. But I absolutely hate using shitty tools, I want something dependable and that feels good in my hand, where the parts slide smoothly without wobble, with great usability.
So, any advice? Unfortunately, I don’t think there’s any opportunity to try before buying, nor any real return period, so I hope the hive mind can help me out!
Thanks in advance!
