This four-piece titanium alloy bi-metal blade set from Smart's Purple series is designed for use with oscillating multi tools, offering extended blade life across a range of cutting applications. The blades feature Smart's Purple titanium alloy coating, which actively reduces friction when cutting through nails and screws embedded in timber. This results in a longer working life compared to standard bi-metal blades, making them a practical choice for carpentry, joinery, and general construction work where mixed materials are encountered. Compatible with most professional-grade oscillating multi tools — including the Fein Multimaster and models from DeWalt, Bosch, and Makita — the set uses Smart's tool-free connection system for quick blade changes on site. Please note: these blades are not compatible with Fein Starlock fittings.
