## What reviewers say

**DeWalt DCS570B 20V MAX XR Brushless 7-1/4 in. Circular Saw** — One whitelisted hands-on source (Pro Tool Reviews, 8.1/10) was verified for this exact saw (the review's spec table names Model DCS570B, the bare tool). Over several weeks of cutting plywood, rough lumber, PT and MDF, the reviewer calls the DCS570 a legitimate corded-sidewinder replacement with smooth bevel detents and a fast electronic blade brake, and standout value, while flagging the push-in trigger safety and the absent rafter hook. (1 sourced review.)

**Skilsaw SPT77WML-01 15-Amp 7-1/4 in. Lightweight Magnesium Worm Drive Circular Saw** — Only one whitelisted tester—Pro Tool Reviews—had accessible review prose for this exact model, naming the Skilsaw SPT77WML its best corded worm-drive circular saw for its 77-series 15-amp power and lightweight magnesium build. No other whitelisted source with accessible measurements was available, so no cross-source comparison exists. (1 sourced review.)
