Sine Bar



The primary use of a Sine Bar is to position the part being machined at a precision angle. Determining and setting up a part at the proper angle is crucial when using a mill or a grinder, or even just stenciling a line on the face of a part. The Sine Bar is used in conjunction with gage blocks and/or a spirit level. Gage blocks are metal blocks that are cut to extremely precise lengths. They are made out of a hardened metal material with a high quality finish that resists, scratching, denting, and corrosion.
