Milwaukee M18 Cordless Metal Shear, Clean, Controlled Cutting of Sheet Metal Without Sparks

The M18BMS20-0 is an 18-volt cordless metal shear designed for burr-free, fast cuts in metal. It features an 8500 SPM motor, a 2-inch blade for efficient sheet metal cutting, and a dial depth control for accurate cuts at various angles. Its compact 7.7-inch length and 3.5-lb weight make it suitable for tight spaces and overhead work, ideal for cutting sheet metal, aluminum, stainless steel, and other thin metal stock.

Key specs include: 18V cordless operation, brushless motor for efficiency, 8500 cuts-per-minute, up to 20,000 N cutting force, 2-inch blade, adjustable depth dial, four-position adjustable guard, adjustable shoe, rubber grip, integrated LED light, and a kit that includes two M18 batteries and a one-hour charger.

It’s designed for sheet metal work and can cut materials such as aluminum and stainless steel. The tool is optimized for thin to moderate thickness metal stock commonly found in ductwork, roofing, and fabrication tasks. For very thick materials, use an appropriate alternative or method.

Use the dial depth control to set how deep the blade cuts into the material and use the adjustable guard for angle control. The tool also offers an adjustable shoe to help position and stabilize the cut. For precise results, position the workpiece firmly, illuminate with the LED, and make controlled passes.

This tool is well-suited for HVAC ductwork, metal roofing and flashing, gutters, sheet-metal fabrication, automotive panel work, and any situation that requires quick, burr-free metal cuts in tight or overhead spaces where a corded tool would be impractical.

Wear eye protection, hearing protection, and gloves. Keep hands away from the blade path, ensure the adjustable guard is in place, secure the workpiece, and keep the workspace clear. Always disconnect the battery before changing blades or performing maintenance, and use the LED light to improve visibility in dim areas.

The kit includes two M18 batteries and a one-hour charger, providing flexible operation and faster turnaround between jobs without repeatedly swapping out power sources.

Power off and remove the battery before maintenance. Access the blade area according to the user guide, remove the old blade if needed, install the replacement blade securely, and re-check for proper seating. Regularly inspect the blade for wear and replace it when cutting performance degrades.
