In the first few seconds after the first cut I could tell that this disc is much better than the Bosch discs I've used. . The cut seems a hair wider, so the blade may be thicker, but most importantly, the Olson's blade is sharper than the Bosch's. Even when the Bosch blade was new I felt like I was pushing the work piece into the blade while the Olson blade cuts like butter with no resistance. I mainly cut plastic panels, but sometimes I need to cut wood or MDF as well. This blade keeps cutting better. I've probably made a few hundred cuts and so far there's no sign of it dulling and no cracking. Quality on par with more expensive Timberwolf blades. I just ordered a few more of these.
