4 way caliper was Re: What is the weak link in machine precis ion - Knee Mills

Hello Andy,

A 4 way caliper is the 6" dial caliper sold these days by HF and many
other machine supply sources. (Who likely have much higher quality.)

The inexpensive ones cost 16-25 bucks. The better ones can cost a
hundred bucks or more (all prices for the common 6" length)

You'll also see them with a digital readout, instead of the 0-100
dial.

Called a 4 way because it measures inside, outside, depth and step.

Hope this helps,

Ballendo
