Best Micrometers for Metalworkers



Which are the Best Micrometers?  What are the best micrometers to buy? Best Rated Micrometers – Top 10 Picks – Micrometer Reviews

By Michael Elson Vice President Penn Tool Co published on February 26, 2017 in micrometers
This list contains the top brands in precision tools such as Starrett, Mitutoyo, Fowler, SPI, and Igaging and we put the list together trying to find out which is the best micrometer.
Any of the micrometers on the list will do the job for you perfectly well.  However, you want the Best Micrometer for the money.  What you after is a device that will give you accurate readings.  So what makes one micrometer better than the other?  A better question is why is one micrometer more expensive than another one.  I ask this question every time I buy a bottle of wine.  What is it about this bottle for $10.00 that I am missing if I bought a $50.00 bottle.
Basically I ask this question every time I buy anything.  For this article lets stick to best micrometers, but the point has been made that basically on every decision you make you are always asking yourself should I spend more or less money for the item in question.  There are several factors that make one more expensive than the other one.  Factors such as price, quality durability, country of origin, and features. High priced micrometers can last a very long time if they are cared for properly.  Some of the lower priced ones are almost like disposable razors.  You know going in that these will get the job done but may not be your go to best micrometer in your toolbox.  These lower priced models might not be there in a few years.  Lets take a look at Best Micrometers!

1. Mitutoyo 293-340 Digimatic Outside Micrometer, 0-1″ Range, 0.00005″/0.001mm Resolution, IP65, No Output, with Ratchet
Number one on the list may I present to you one of my favorite and most popular micrometers.  The Mitutoyo 293-340.  Back in 1934 the founder of Mitutoyo Yehan Numata started his company with one product in mind.  THE MICROMETER.  Many years have past but Mitutoyo is still making some of highest quality micrometers around.  They have gone digital now and perform like as you would expect something out of Japan to perform.  Think of your favorite Japanese car. Or if you don’t like Japanese cars, you certainly are someone who appreciates craftsmanship and value.  That is what you get with the Mitutoyo 293-340.  Coming in at under $150.00 the micrometer is certainly one of value.  Priced just right.  Not too high and certainly not so low you are thinking this has to be a piece of crap.  No need to protect this in your toolbox.  This micrometer comes standard with a hard plastic case that will protect your measuring device for many years down the road.  With carbide tipped measuring faces can you really go wrong?
Mitutoyo Coolant Proof Micrometer – 293-340

2.  iGaging 0-1″ Digital Electronic Micrometer w/Large Display Inch/Metric

IGaging Part# 35-040-025
IGaging is a relative newcomer on our list and it has been selling fast.  Priced on the lower end of the spectrum, the IGaging 0-1″ Digital Electronic Micrometer will not disappoint.  For under $75.00 you are walking away with a device you can count on for accuracy but won’t break the bank.  Hobbyists and students who may be just getting into the metalworking industry might want to jump in at this level and get their feet wet.  I compare this model to maybe shopping at IKEA.  You know when you are walking in that you are not looking for high end high priced furniture.  However after walking around and sitting on some beds you are like wow this furniture is half bad.  That is how we feel about IGaging.  Wow, you are pretty damn good!

3.  The Starrett 795XFL-1  Starrett LCD Outside Micrometer, IP67, Friction Thimble, Lock Nut, Carbide Faces, Inch
What can we say about this bad boy is that it’s made really well.  Everything you would expect from Starrett.  A company who still manufactures its tools in the good old USA.  I compare this to the Ford Mustang.  Made in America and solid.  For all those people out there who only want to buy American but say they can’t find any good options.  The Starrett 795XFL-1 will not disappoint you.  You have your Ford Mustang or Harley Davidson in the palm of your hand now.  Comes in a little on the high side of a 0-1″ micrometer, but you get what you pay for.

4.   SPI IP65 Electronic Outside Micrometer 13-731-5
At #4 we are happy to show you the SPI 0-1″ Outside Mike.  She is a beauty and the best thing about this dream micrometer is it’s NIST Certified Right Out of the Box.  That is a savings of about $50.00 right there and coming in total at under $150.00 this best micrometer certainly is a steal.  Not only are you getting a great micrometer, it is also testing for accuracy and supplied with the certificate proving it!  Wow that is great don’t you think?  SPI warranties it’s product for a year so you know that you are in good hands with this Micrometer.  I think you will be really happy with the value you get here and lots of Penn Tool’s customers agree.  Go with the SPI- “Your Partner in Precision.”

Coming at #5 a brand that never disappoints, the Fowler 54-860-001 is oh so sweet and under $90.00 at the time this article was written.  Fowler has always been synonymous with high quality and great value.  Our boys from Boston, actually Newton Mass, give it their all like the New England Patriots did this year in the Super Bowl.  I am not saying that Fowler is some come from behind brand, but they are like an old reliable pal.  Always there for you and not going to rip you off.  What else do you want in this micrometer?  Pick up one of these and you are sure to be as happy as Tom Brady.  Well maybe not that happy, but try out some Fowler Tools and you are sure to smile knowing you got a great tool.

NEWAGE Electric Arc Etching Pen Model 300



NEWAGE Electric Arc Etching Pen Model 300

Metal Etching Engraver NEW-300

The Newage Etching Pen makes a permanent mark on any metal using an electric arc. The mark is actually incised into the surface and is as permanent as the surface on which it is written.

To operate the power cord, pen, and return wire must all be connected. Hold or clip the return wire anywhere on the part and start writing with the pen - just as if you were using a regular pen. The Etching Pen uses a unique design to make the pen tip move smoothly and easily. When the tip becomes worn out it may be replaced easily. Users may select either of three settings for a heavier or lighter mark.

The Etching Pen Is Well Engineered
  • Electric arc etch any metal
  • Writes like a pen - unique vibrator makes writing easier than other models
  • All replacement parts are readily available
