The Series 60 DW7657 40T was DeWalt's answer to the Forrest WWII 40T. It's considered to be a true dark horse and stellar performer by many, myself included. Some changes have occurred since B&D bought Pentair, which put DW and Delta under the same corporate umbrella. The DW series 60 appears to be changing to, or at least expanding to include the Delta Industrial line. Many of the DW Series 60 blades are now badged as a top line Delta blades. Ie: the DW7657 is now available as a Delta 35-7657.
Amazon's been having a 20% off promo for the past week or so. When combined with regular sale prices, some incredible deals pop up. I considered the DW7657 to be a pretty solid bargain @ $50. Amazon is currently offering the 9" version of the 7657 (the Delta 35-7656) for $25 shipped. I'd prefer it to be a 10", but at $25 shipped, the price is too good IMHO to not post about it. It should have very similar performance to the DW7657...you'll give up 1/2" height capacity, blade tip speed will be slightly slower, and the attack angle will be slightly steeper. 40T, C4 carbide, 20 degree hook, full 1/8" kerf, made in the UK.
So if you've ever wondered what all the fuss about the WWII is, but just can't part with $75-$110 for a blade, here's a taste of that performance for the price of a big box cheapo.
