Digital micrometer

[Blastattack]

I have only ever used digital vernier calipers, faster, easier, etc. And, they meet the accuracy I require from a vernier caliper, or a "very near" calipers as I refer to them when talking with new apprentices.

Digital Micrometers are for people who dont know how to properly use a Mic. All of my Mics are graduated to 0.0001 increments - have to be for true precision. The problem with digital measuring tools is the computer is usually graduated in 0.001 or 0.0005 increments, meaning that it rounds to the closest number. Not good when the tolerances on some things I've done have been +/- 0.0001.

The only definite advantage that digital mics give is the tradesman wont suffer from 25 thou disease.....

Just my $0.02

Agreed with that. I have a very nice Mitutotyo digital vernier that I use for "roughing", and a full 0"-6", .0001 Micrometer set for just about everything else. Though I've not yet tackled anything in tenths, I did have to precision for a hole .498-.500. I would never even think of using a vernier or any stripe for that. Small hole gauges and a Mic are the only choice.

Another .02 for the pot

talon brand name

My digital calipers turn themselves on as soon as you move them to start to measure something... so you only need to remember to turn them off. I just picked up some calipers from my industrial supply guy, solid stainless and the battery in his set has lasted two years. He uses his many times each day.

I'm going back to find out if he has a "digital micrometer" from the same maker. The label on the case says "Talon Tool". Nothing on the instrument or documentation says who made it. TALON is Swiss brand name

And for those of you who hate batteries, yes, Mitutoyo has a solar digital caliper. Only about 50% more than the equivalent battery-powered one. Ouch.

Talon is a brand made in swisszerland

I find the digital stuff to be very handy but am just as happy to use a dial. I have a digital vernier, dial vernier and regular mics. All higher end stuff (Mitutoyo etc). I have used the cheaper digital verniers and they seem ok and appear to be accurate. They do have a slightly rougher feel to them.

Don`t have any digital mics but i do like my Mitutoyo caliper, i have a few cheap digital calipers that i use for rough work or to loan to the boys. The Princess Auto caliper is hard on batteries.

Calipers, whether digital or dial or conventional are great for convenience and rough work. True precision is achieved with micrometers, bore gauges and bore mics. Even the finest digital calipers only have repeatable resolution of + or - .0005 inches. Therefore they are fine for 95% of machinist work but for high tolerance work they are unacceptable. Anyone who makes their living as a machinist knows that.

 

[crazy insane]

digital all the way 0.0005 resolution is good enough for most people, just dont drop them, and stay away from Chinese made, Japanese is the best
