Square Slot Cutter for Dewalt and Milwaukee Multi-Tools

This square slot cutter is designed for Dewalt 20V and Milwaukee M18 oscillating multi-tools, with included adapters for broad tool compatibility. It cuts electrical outlet boxes and wall openings in a single pass without marking or pilot holes.

The cutter features hardened manganese steel with a sharp, evenly-spaced serrated edge that delivers clean, precise cuts without rough edges or chipping. Double-wall welding and reinforced corner ribs enhance durability and impact resistance for extended tool life.

Available in two sizes—3.8″ × 3.8″ × 1.57″ and 3.8″ × 2.36″ × 1.57″—both fit standard single-gang US wall boxes. The one-step cutting action saves time on drywall work, whether for professional electricians or DIY home projects.

Check compatibility with your multi-tool before purchase and ensure you have the correct interface adapter included in your kit.
