The Freeman 55-Piece Impact Driver Bits and Oscillating Blades Kit with Case is ideal for DIYers tackling home improvement and repair projects as well as professional construction contractors at the job site. The hex bits are universally compatible with all brands of impact drivers and are built to last up to 10-times longer than standard screwdriver bits. The cutting blades are heat-treated for strength and durability and outperform overpriced comparative replacement saw blades to cleanly and precisely cut materials such as wood, metal, drywall, plastic, fiberglass and PVC. A three-dimensional design reduces vibration and provides a higher torque transfer for tough jobs. These metal blades in the bits and blades kit are compatible with most oscillating multi-function tools, such as the Freeman PMTCKWB and those by DeWalt, Milwaukee, Makita, Ridgid, Porter-Cable, Fein, Dremel and more. This 55-piece kit of the most commonly used bits and blades includes 40 impact-ready hex bits and 15 cutting blades, each with a black oxide finish to resist corrosion and enhance durability. The bits and blades kit also comes with a zippered EVA case for grab-and-go convenience and will get you back to work quickly when you need a new impact driver bit or sharp cutting blade for your oscillating tool.
