Why choose it

The bi-metal construction with 8% cobalt combines a tough, flexible body with hardened cutting teeth, allowing the saws to withstand the heat generated when drilling stainless steel and other hard metals. The variable tooth pitch reduces vibration and helps prevent snagging, while the two included arbors cover both small and large diameters, so you can switch sizes quickly without buying extra accessories.

Ideal use cases

• Cutting holes in metal enclosures, panels, and pipes
• Installing electrical outlets, recessed lights, and plumbing fixtures
• Creating openings in wood, plasterboard, and plastic for cable routing
• Professional and DIY applications with cordless or corded drills

Good to know

The set is made in Germany and packaged in a sturdy case that keeps the saws and arbors organised. The hexagonal shank on the arbors ensures a secure grip in the drill chuck and prevents slipping under load.
