DeWalt 10in 80T TK crosscut blade

I was in my local BORG today, saw this blade on clearance for $37 (reg. $50) - was wondering if anyone has experience with this blade, and if its a good value at this price.

Some of the DeWalt blades are very nice. They make a construction version which is a stamped plate and lower-grade carbide that isn't that great. They also make a cabinet-grade that is laser-cut and has (I think) C3 carbide that is an excellent blade.

I've tried the DW3218TK, which is a Series 40 blade with the black Teflon coating made in England. Was it that one or is it the newer yellow DW3218PT? The 3218TK is a very nice crosscut blade...$37 would be a decent price for it.

It's the 3218PT, in the yellow. As cgallery mentions, it is laser cut and has the thick C3 carbide.

I've tried the 50T DW7150PT from that series and thought cut very nicely for that type of blade. The lettering seemed to wear off prematurely but still does a nice job. Never tried the 80T PT, but I think the PT series has replaced the Series 40TK line so those two blades may have some common ground....hope it serves you well!

I think I'll give this a try, and post my observations. Thanks Dustmight and cgallery for your input.

So I picked one up to see what it could do.

I've been pleased with the results I get from the CM 36T combo blade that came with my 21829, and the Ryobi 60T finish blade I picked up for crosscutting. So I decided to compare the results of each on some scraps I had at hand, to see if I could appreciate the differences between these and the DeWalt 80T.

I crosscut some 4in-wide scraps of red oak and Phil. mohagany, using each blade.

There is a notable difference in cut between the 36T and the others, as expected - the cut was good, but reaffirmed its intended use.

Between the 60T and 80T, I don't really see much difference - both are extremely clean cuts - except that the 80T produced something I didn't expect: although this blade was more quiet (in high pitch), there was a new, minor low-pitch harmonic resonance, which did not affect the cut. And where the 60T offered little resistance to the wood when cutting, the 80T was so smooth, had so little resistance, it seemed like the wood was melting away before all that carbide.

So I think I'll keep it, and I'm looking forward to seeing how it performs on whatever project next comes my way.
