Mitutoyo Micrometer 60˚ Modification

[Fire4Effect]

I have a Mitutoyo 115-313 spherical anvil tube micrometer with a flat spindle tip. Does anyone offer a service to modify the Mitutoyo 115-313 for the 60˚ spindle tip offered by K&M on the Mitutoyo 115-313?

I did mine using a diamond wheel in a friend's machine shop; it was easy to do freehand without disassembling the micrometer.

Thanks. Unfortunately I don't have access to a friend's machine shop.

Maybe start your own? 6X30 Norton OD grinder.....

I’m working on tablet unfortunately and accidentally touched the ‘Like’ response to this answer above. But I can’t get rid of it no matter what I’ve tried. So I’m responding to say that I do not agree with manually grinding a bevel on a micrometer. This is not the place to attempt to use a DYI idea.

If you click on like again, it should disappear. Matt

The bevel is a non-critical surface - it doesn't contact anything; its only purpose is to reduce the diameter of the micrometer face so it can be used to measure closer to the case shoulder. The micrometer face is usually carbide, so it does require diamond tooling to work it. Harbor Freight and others sell inexpensive diamond tool assortments for Dremels or flex-shaft tools that would do the job, although slower than a diamond wheel on a grinder (probably a good thing). It comes in handy for other uses around the house, such as sharpening my carbide-toothed chainsaw chains.

You’re entitled to your opinion just like I am. We’re not in agreement as to certain procedures. It’s not wrong or right just opposing thoughts.

I am pleased to report that I have found a company to do the 60˚ modification for a reasonable price.

Can you post the company please?

K&M said they would do the modification.
