Standards for a Mitre Saw

Often the bevel setting can’t be relied on – you have to set the stop for
a perfect 45. The miters should be dead-on.

Higher quality saws have positive shot pin metal-to-metal type arrangement
for the miter settings to common angles. On the saws I’ve owned,
the bevel always had to be fudged.

Most miter saws can be calibrated by adjusting the position of the scale/stops.

If your back fence can be adjusted (and most can), let your saw “snap in” at 45*, then use your standard to set the back fence. That’s how I do both of my miter saws.
