They turn on and seem to hold tolrences
Can you tell me what is it for ?
its for alot of things, it can be used as a travel indicator for moving in precise measurements if you machine does not have a DRO. it can be used to check flatness of a mill or lathe, another use is to mount it to a surface plate and measure the depth of holes. there are alot more uses but these are to name a few. Thanks for asking!
Ok so for 2 bucks that's a steal ! :D
