Don't run out of blades mid-project! This huge 50-piece set has you covered for almost any cutting job with your oscillating multi-tool. It includes a bunch of 1-3/8 inch blades perfect for cutting wood, drywall, plastics, PVC, and even soft metals. They feature a universal quick-release design that fits most major brands like DeWalt, Milwaukee, Makita, Ryobi, Rockwell, and Bosch (but note: does NOT fit the Bosch MX30 model). The blades are made from high-carbon steel for durability and sharpness, and they even have handy depth scales printed on them (in both inches and mm) so you can cut to an exact depth. Great for pros tackling renovation work or DIYers handling home repairs. Remember, these are for wood/plastic/soft metal - don't try to cut hardened screws or bolts with them, you'll just ruin the blade. An incredible value pack that saves you multiple trips to the hardware store.
