WOOD magazine review

Miter detent override, vernier scale for super accuracy

Review Summary

High points: One of two saws with a detent override; this feature allows you to position the saw close to the miter stops without slipping into them. The 45° miter stops proved dead-on right out of the box in our 8-miter frame test. Its vernier scale helps you pinpoint a miter position accurate to within 1/4°. Dual safety switches on the right and left sides make it convenient for you no matter which hand you use to operate the saw.
Low points: The bevel stop system won’t allow angles beyond 45° without resetting the stop. You have to recalibrate it to establish the 45° stop again. Miter adjustments were stiff though manageable. More points: The hold-down clamp features a quick-release lever; however, it gets in the way when not in use.
