Pairs well with

Blade

24-tooth framing blade (match your saw's size & arbor)

The everyday blade for 2x4s and deck boards: fast, forgiving cuts.

Blade

40–60 tooth fine-finish / plywood blade

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

Check price →
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.
