Notes

Miter saws are heavy-use power tools where bearings, switches, and alignment parts wear over time. Repair is worthwhile when the base and fence are true and the issue is a replaceable part like brushes, switch, or guard.

Replace if the saw won't hold alignment, has severe bearing play, or the arm/base is damaged from drops. If multiple wear items stack up (bearings plus switch plus alignment), replacement often becomes the better value.
