Quick Tip: Draw Circles And Bisect Angles With A Reciprocating Saw Bladehttps://www.tool-rank.com/media/listing/videos/thumbnail/300x300s/d9/83/20/geH9vqmJ7m8-v1405494981.jpg
Have you ever found the need to draw a perfect circle but you don't have a compass (drafting) or anything round to trace? Well, if you have a reciprocating saw blade laying around, you can use it to make near perfect circles in a wide range of sizes.
Using the hole on the blade shank as the pivot point and the gullet between the teeth to guide your drawing point, you can make a circle anywhere from 2" up to almost 12". Your only limit is the size of your saw blade.
And because you are using the reciprocating saw blade the same way you would use a compass, it can also do other compass things, like draw right angles, or bisect angles. To show just how easy it is, I made a quick little video (below).
