Digital Outside Caliper inch/Metric/Friction (35-OD6-H)

Definitely go for the spring loaded version over non-spring...much easier to use. My application is for guitar necks and it works perfectly.

Handy to have

This is a really great addition to the wood turning corner of my shop. When turning long pieces, I frequently turn both ends to the diameter I want (plus a little extra to account for sanding), and then work towards the center. If the piece is tapered (like a pool cue) I will calculate what the diameter should be at several places along the piece. Then turn each point to the appropriate diameter, and then "connect the dots" by turning the sections between those points. This digital outside caliper is fantastic, because the calculations usually end up being numbers out to several significant digits. I can set the diameter with this tool very precisely. The only reason I have not marked it as a 5-Star item is because when placing it on the turning piece, it is possible to have the setting get a little enlarged by pressing too hard when checking my progress. You have to turn the set screw really tight to avoid this from happening, and I worry about wearing out the threads or the sliding arc that the set screw binds against to fix the setting. So, I use this tool to set the diameter, then transfer it to a set of conventional outside calipers to actual checking the progress at each point. Serious wood turners, THIS is a fantastic tool for the price!

Très utile pour des mesures rapide

These are far cheaper than most digital calipers but are more than adequate for most of my needs. They are cheaply made but do a great job. Get the warranty and just use them .I love that they have fractional and decimal inches as well a mm.
