❓ Frequently Asked Questions
Can it cut a 2×4?
At 90°, the 1-5/8″ depth can cut a 2×4 (actual 1.5″ thick) but just barely. Not ideal for framing.
Is a 5-1/2″ saw useful?
Yes — for plywood, trim, shelving, and thinner materials. If you cut 2x lumber often, get a 7-1/4″ saw.
What blades does it use?
5-1/2″ blades with a standard arbor. Fewer options than 7-1/4″ but Diablo and Freud make quality 5-1/2″ blades.
