I use a Montolit DNA blade, still good and cuts brilliant.
I've replied to this topic many times on various posts, I even I get fed up with myself, so sure you do.
I listened to people and bought a Monolit to replace the original DW2400 blade and it was poor. First concern was the cut was not as clean. This was surprising as the build of the blade looked great.
Its performance got worse too quickly and was relegated to ceramics which it could cope with easier, but eventually put to rest.
I bought a new DW replacement and made direct comparisons and the DW came out way better. I have stuck with the DW blades and I can vouch they cut better, cleaner and last longer without any doubts.
I might add the Monolit was way over priced too.
I should add I cut hard porcelain mostly, so not a bad test for cutting requirements.
I reported the findings to the recommended supplier who was decent enough, but went quiet after explaining my results.
I recommend shopping around for the DW at £50 and save yourself a bunch of money. You will not get a better cleaner cut than the DW.
