Sine Bar



The primary use of a Sine Bar is to position the part being machined at a precision angle. Setting up a part at a precise angle can be crucial when using a mill or a grinder. The Sine Bar is used in conjunction with gage blocks. Gage blocks are metal blocks that are ground to extremely precise thicknesses. They are made out of a hardened metal material with a high quality finish that resists, scratching, denting, and corrosion.
