A Quick Circular-Saw Blade Change

If you need to change out the saw blade on your circular saw, you could fumble around with a blade stop and look for a wrench that barely fits the nut and probably bust your knuckles in the process, but there's a better way.

This tip is so smart that most of us are going to wonder why we didn't think of it. Here's what to do:
Grab your imact driver (most cordless tool kits have one these days), put in a socket-wrench adapter with the correct size socket for your saw-blade bolt, and fire away. NOTE: be sure you know which way your bolt is threaded--if the blade is on the left side of the saw and it spins counterclockwise, the bolt will loosen by turning to the right.

That's all there is too it, folks. You don't even have to block the blade to keep it from turning.

The "impact" that the impact "driver" (which is actually a misnomer for the cordless power tool in the video) delivers can easily damage the saw's internal gears...ask me how I know. Repairing power tools for a few years taught me a thing or two about what they'll stand and this is a really bad thing to do to your saw. Use the spindle lock and supplied wrench (which often fits right into a holder on the saw)
