What we like

  • Lightest saw here (3.5 lb bare)
  • Electric brake and left blade for a clear view of the line
  • Still cuts a 2x4 at 90° in one pass

Keep in mind

  • Shallow 45° depth (1-1/8")
  • Smaller 4-1/2" blades are less common in stores

Blade

40–60 tooth fine-finish / plywood blade

More teeth = cleaner edges and less splintering on plywood and shelving.

Guide

Kreg Accu-Cut or Rip-Cut style saw guide

A straight edge you clamp down makes perfectly straight cuts much easier — huge confidence boost.

Check price →
Support

Folding sawhorses + a sheet of foam board

Support the board on both sides of the cut so it doesn't pinch the blade.

Check price →
Safety

Safety glasses (ANSI Z87.1) & ear protection

Saw manuals call for eye protection; cordless saws are loud (DeWalt declares 91 dB(A) for its compact saw).

Check price →
Clamps

A pair of quick-grip bar clamps

Hold the workpiece and the guide so both hands stay on the saw.
