Accurate : Made of CNC precision machined and coming with precision laser engraved scales, the angle finder tool is reliable for measuring both internal and external angles, provides accurate angle calculations,Easy to Use : The protractor angle finder is featured with inside & outside scales to measure angle for single cut and miter cut. For a single cut, please use the inner arrow and outer scale, eg 30° produces 30°angle. And for miter cut, please use the outer arrow and inner scale, eg 35°produces 70°angle,Design : The O-ring design allows the metal protractor to fully rotate 360 degrees, which is easy to adjust and capture angle measurement, ensuring reading inside/outside angles smoothly and accurately,Quality : Made of the 1/4 inch thick rust-proof anodized aluminum alloy, the miter protractor is stronge and won't bend like the plastic protractors. The precision laser-etched scale on the miter gauge will not be scratched easily, it lasts for a long time without fading,Wide Application : The miter saw protractor is suitable for inside outside corner measuring, crown molding, miter cuts, carpentry, plumbing, metalworking, beveling, trimming, and various other woodworking applications

The Steps to Use this [item]
Step 1 Place and Hold
Hold the angle measuring tool against the corner you are measuring. Firmly push against the arms of the protractor making sure they fit against the corner with no gaps visible.
Step 2 Take Measurement
Decide to use single cut or miter cut. Read the scale and look for the correct arrow and scale.
Step 3 Single Cut / Miter Cut
* For single cut, pls use the inner arrow and outer scale. eg 30° produces 30°angle.
* For miter cut, pse the outer arrow and inner scale. eg 35°produces 70°angle.
Step 4 Transfer measurements to miter saw Refer to the conversion table, convert the reading to the right angle for the miter saw to carry out cutting.
