I own a Makita 3 1/8" powered planer, model 1900B. I went looking for new blades on ebay one day and found a site that sold them. The blades fit 23 different makes. About 6 of then appeared identical except for color. The Hitachi was also a 1900B model. Obviously Makita didn't make that tool and neither did Hitachi. I don't know how many of Makita's tools that would apply to but I suspect it's a few.
