The CMT 213.040.10 is a full kerf premium 40 tooth ATB saw blade intended mainly for use on a TS. I really wanted to like this blade…the attention grabbing orange color is so cool, plus it gives a constant warning to keep hands away. This was to be my new daily user for my new Shop Fox cabinet saw, but ultimately I’m disappointed as it underperformed expectations. There are pronounced swirl marks on the edges of every cut that make glue-ups straight from the saw marginally acceptable. The marks are large enough that you can feel them fairly easily. The quality of the cut looks it came from a low quality 24 tooth rip blade, not a premium 40 tooth general purpose blade. On the plus side, it’s fairly free from tearout on the backside of crosscuts, but the edge marks remain. It’s made in Italy with precision manufacturing techniques, high grade materials, and is a common general purpose design, so there’s really no reason it shouldn’t make better cuts. Performance is among the poorest performing of all the higher grade general purpose blades I’ve tried. My $25 Oshlun is better, as are all my Freud, Forrest, Infinity, Tenryu, DeWalt, Delta, Leitz, and Amana blades. I have other CMT products that perform well, so perhaps this one is simply “not quite right” but at $60 it’s unacceptable as my “go to” blade.
This one got returned, and replaced with an impressive Series 60 DeWalt DW7640 (more to come on that one).
Followup April 2010:
A sale with 50% off CMT products from Woodwerks.com presented a great opportunity for me to give the 213.040.10 another try. Amazingly, the 2nd attempt was very similar to the first….unacceptable. The saw marks from this blade are easily visible, can be felt, and are too pronounced for glue up without additional attention from a jointer or handplane. I’m surprised and disappointed to get this kind of performance from a premium blade. I’ve used several other good 40T and 50T general purpose/combo type blades that I can glue up straight from the saw with no additional machining required (Forrest WWII 30T and 40T, Infinity Super General, General, and Combomax, Tenryu Gold Medal, RS25540, and RS25550, DeWalt DW7657 and DW7640, Freud LU84, LU86, and LU88, Oshlun 40T, Craftex Blue Tornado, Amana 610504, etc).
It was fairly easy (and logical) to chalk the first one up as an “escaping defect” from the factory….it happens to all of them from time to time. The 2nd one was purchased from a different retailer close to a year apart. The problem could still be a 2nd escaping defect, or could even be part of the same bad run as the first, but the probability of that being the case is fairly slim. This is a fairly straight forward 40T ATB general purpose design. I’ve double checked the saw to rule it out as a possible cause, plus I’m getting great results from several other blades. It’s possible that CMT’s execution of this design is simply mediocre, but I’ve read about several others being very happy with this blade. I’ve tried several other CMT products with excellent results that I’ll heartily recommend when they fit the need, but I can’t recommend this particular blade.
