Opinions anyone??

Everyone look for IPF56...I believe that's correct for the Coolant resistant one. Fowler, Mituoyo, etc. they all have one.

The one I found is a Mituoyo IP67 coolant proof, kind of expensive though.

Just picked up two micrometers here last week [insurance replacement], and both were rated well..
the starrett dial type was rated 66 and the mitutoyo digital was rated 67...

basically first number [ie 6] means its sealed against dust or other dry particles..
second number [ie 6] means strong jets of water or spray, and 7 indicates protection against prolonged immersion at depths of up to 1 metre..

more detailed information available at

in case you're interested, the Starrett 6" dial was $185, and the Mitutoyo 8" digital was $260.. Canadian funds.. 'bout $20. US it seems some days..

enjoy..

I've had my Mitutoyo coolant proof micrometer for a couple of years and it's very good.

I dont care for digitals but my guys like them i got them the mitu. and i got them for $109.00 they are reg. $163.

Sorry i was thinking calipers!!!!!!

I've got four Mitutoyos... 0-1, 1-2, 2-3, and 3-4. All are excellent IP67 coolant proof.
