The Milwaukee Electric Tool Corp IBSL340-3 is a 3-pack of Starlock-compatible standard metal oscillating blades sized at 1-3/4 inches. These blades are designed for use with Starlock-interface oscillating multi-tools and are built to cut through standard metal materials encountered in trade work. The Starlock mount provides a tool-free blade change system that seats directly onto compatible oscillating tool arbors without an adapter, delivering a secure, vibration-reducing connection. Licensed HVAC techs, plumbers, electricians, and general trade contractors use these blades for cutting sheet metal, nail-embedded materials, and metal fasteners in tight or confined spaces.
These 1-3/4-inch standard metal blades are suited for residential and light commercial applications where controlled, precise metal cutting is required. Typical use cases include cutting copper pipe, conduit, sheet metal flashing, metal lath, and threaded rod during rough-in or service work. The compact 1-3/4-inch blade width allows for work in restricted access areas such as wall cavities, junction boxes, and mechanical chases. The 3-pack format reduces interruption on multi-stage jobs where blade wear is expected.
Designed for use with oscillating multi-tools equipped with a Starlock-compatible arbor interface.
Installation and blade changes should be performed with the oscillating tool powered off and unplugged or with the battery removed. Starlock blades seat onto the arbor without tools — follow the tool manufacturer's blade-change procedure for the specific oscillating tool in use. Wear appropriate eye and hand protection when cutting metal, as chips and burrs are common. Inspect blades for wear or cracks before each use and replace if deformation is visible.
