What device is used to measure the accuracy of a tool such as a drill press or a lathe? What is a good brand and price?
Thanks!

you can use a dial test indicator (DTI gauge), get one with a magnetic base as it is useful for getting the gauge into akward positions. It looks like a small dial with a little lever poking out of it. They vary in price depending on the make but i have found the cheap ones work well enough. Probably start in the region of $30.

Tmac,
Enco has a suitable Swiss style dovetail mount indicator that will work well for this purpose. It is currently on sale for $36.95 and the model number is #PW606-4710. It has a .030 range and the dial is marked 0-15-0 in .0005 graduations. They also have an on-off dial indicator base for $19.95 also on sale. The model number of the base is #PW505-1848. This type of indicator is suitable for many tasks that involve alignment and centering. There are more expensive indicators such as INTERAPID but the $36.95 model Enco will do the same thing and should serve you well. Enco’s phone number is 1-800-873-3626.
