Title: POOR PERFORMANCE
Review: I used the first of 5 blades on 1/4" cement board and got about 1" of cut done (very slowly) until the blade heated up, became soft and bent, making it useless. On the second blade, I got about 2 more inches and the same thing happened. I was not heavy-handed with the blade. I didn't bother with the other 3 blades and asked amazon for a refund, which they obliged (thanks amazon). This product is totally unsatisfactory for the purpose given in its product name. The Dewalt website offers absolutely no information on it either. I checked to make sure the product was intended for the purpose I was using it for. Apparently Dewalt doesn't know either. I ended up using a chisel to get through the cement board and used a Bosch wood blade (for the same jigsaw) to finish the hole in the subfloor. I highly recommend against this product. One would be better suited to buy inexpensive rip saws and change the blades frequently than to waste money on these blades.
