Review on HEMUNC 5pcs Mixed Universal Carbide Oscillating Tool Blades Set - Quick Release Saw Blades Accessories Kit for Tile Grout, Mortar, Concrete, and Masonry by David Norwood

I ordered this set primarily for the small spear blades as I couldn't find any others that would fit in the small space I had to work on under the door jamb. They fit my Fein Multimaster and have exceeded my expectations. They are much more aggressive and slightly thicker than fine OEM blades. They worked surprisingly well on my 1/4" seams. I think they might be too thick for very small seams, but they're perfect for my purpose.
