They also fit the old Delta 37-280. Very good two beveled edges, absolutely faithful, beautifully cut. I was concerned that these blades were 1/32 thinner given the nasty 37-280 blade clamp pattern. Fortunately, this is normal. I have nothing to say about the Delta 37-280; With a flexible guard, no output table adjustment, no blade lifter, and a poorly designed and manufactured clamp that tends to misalign the blades, I plan to spend at least 2 hours of misery adjusting the blades with a magnetic-based dial indicator. . I strongly recommend avoiding the aftermarket 37-280 at all costs.
